How to make lighting in the steam room. How to make lighting in the bath with your own hands? What needs to be considered? Maintenance and preventive inspection of electrical appliances and wiring

Many people like to spend their free time in the bath. Such a vacation is a very pleasant procedure and is liked by almost every inhabitant of the country. As a result, a considerable number of people want to build their own bath.

The construction of the bath itself involves many stages, and one of them is to carry out electrical wiring and create a lighting system.

It is worth noting that for this type of building, the presence of a light supply system is very relevant, since the design itself provides for a small number of small windows.

Working conditions of lamps

Creating a bath lighting system with your own hands is accompanied by its own characteristics and, first of all, depends on the conditions that are observed in the room. As you know, the main conditions for the functioning of the sauna are:

high air temperature, especially in the steam room;
high level of humidity.

Actually, the last factor plays a very important role in creating lighting in most sauna or bath rooms.

Moisture is the factor that increases the level of danger to the life of sauna users. In addition, it can lead to a short circuit in lighting fixtures and, as a result, the possibility of a fire.

Given these two conditions, bath lighting must be protected from moisture and heat. The entire lighting system consists of a switchboard, wiring, switches and the fixtures themselves. First, let's look at the features of the lamps themselves.

requirements for luminaires

Sauna lamp

The main requirement for any lighting device that will be used in the sauna to create a lighting system is called tightness.

It should not allow any moisture to pass inside. Its design should provide for the presence of a waterproof housing and ceiling. In this case, a sealing gasket must be between the ceiling and the body.

It is desirable that the light bulbs be low-voltage. Be sure to use RCDs and circuit breakers when creating lighting in a sauna or country bath.

Note that the bath involves the presence of such premises as:

Waiting room.
Basin.
Washing.
Steam rooms.
shower room.

Steam room lighting

The most important room in the bath can be called a steam room and the requirements for its lighting are the most stringent. The reason for this lies in the fact that very high temperatures and high humidity are created here.

As a result, the light source must be heat-resistant and waterproof.

So, if lighting is created in a Turkish-type bath, then the heat resistance of the device should reach 150 degrees Celsius. The lamp for the steam room of the Russian bath or sauna can withstand a temperature of 120 degrees.

In the event that installation on the ceiling is carried out, then the heat resistance should reach 200 degrees Celsius. The maximum power of the lamps should be 60 watts.

As for the type of lamp that will create lighting in the bath, it is advisable to use only an incandescent lamp. Fluorescent and LED lamps should not be used.

First, they are not designed for such conditions. Secondly, at high temperatures, fluorescent lamps can explode, which must not be allowed.

Helpful Hint: The best option for providing light is to use a fiber optic fixture. Optical fiber can withstand up to 200 degrees Celsius.

Any lighting device that is located in the steam bath must be protected by a wooden decorative grille. This will eliminate the possibility of direct contact with the ceiling, as well as soften the light.

By the way, the light should be soft and diffused. It should not be characterized by brightness.

Usually, two light sources are installed in the steam room. At the same time, they try to place them as low as possible. The switch must be outside the steam room.

Washroom, pool and dressing room lighting

The creation of a lighting system in the pool, washroom and shower is the same. The requirements are also the same. There is no high temperature here, and fluorescent and LED lamps, as well as LED strips, may already be at your disposal.

In this case, the latter can be installed on the walls of the pool. Of course, these tapes must be sealed, that is, they must be protected from water. The lighting that is created by one's own hands in these bath rooms should be bright enough.

All fixtures that will be mounted in these rooms must have at least IP44 protection. They must have waterproof covers.

Helpful advice: the switch must be taken out to the dressing room. This increases the level of security.

Wall lighting fixtures must be installed in such a way that they cannot be touched or damaged.

As for how to make lighting in such a bath room as a dressing room, this procedure provides for the least number of requirements. Here you can install any type of lamp. It is desirable to place all switches and sockets in this room. The light must be bright.

These are the features of organizing lighting in a sauna or bath room and you need to know them when installing a lighting system with your own hands.

Calculation of the number and power of fixtures

In the future, we will focus on the very stages of bringing light into the bath. From the very beginning, they develop a project and make a calculation of the required number of devices for supplying light. This calculation depends on the type of room.

Note that each of them needs a certain level of lighting. So, the average horizontal illumination of the dressing room should be 150 lux or 150 lumens per square meter. You need to determine the area of \u200b\u200bthe dressing room and multiply the number of square meters by 150 lumens.

As a result, you will know how many lumens all fixtures should create.

Accordingly, the next task is to determine how many lumens one watt of the lamp that you plan to use creates.

After that, the total number of lumens is divided by the number of lumens that one watt of the lamp produces. As a result, we will know the total power of the dressing room lighting in watts. Next, the required number of light bulbs is already selected, taking into account their power.

Similarly, the procedure for calculating the power of the light supply system for other bath rooms is carried out, in which lighting is created and the photos of which can be seen below.

Steam room lighting
Sauna lighting with LEDs

neon lighting
Floor lighting

Decorative pool lighting
Pool lighting inside

Note that the level of illumination of the washing, shower, steam room and changing rooms is 75 lux, or 75 lumens per square meter. For a pool, this value is 100 lumens per square meter.

After calculating the total power of the lighting system, they begin to install RCDs and automatic machines, lay wiring, and also install switches for the fixtures themselves.

Wiring Requirements

I would like to talk more about the requirements for wiring. Each wire must have a double insulating layer. Experts note that the most preferred option is the use of flexible VRG and AVRG embedded in a PVC sheath and special rubber insulation.

They must be two- or three-wire. Wires that have a metal sheath cannot be used.

In saunas that have internal wood paneling, the wiring must be open. Wires should only be laid in a straight line, both horizontally and vertically.

A bath is a place where you want to have a great rest, relax, forgetting all everyday problems. And to make your vacation as great as you planned it, you need to think about all the amenities of the steam room, including the right lighting. This is exactly what we will tell you in this article.

It is enough to apply a little imagination to skillful hands and the lamps in your bath will become not just utilitarian lighting, but will be integral elements of the design of the room.

How to conduct electricity in the bath

You need to be a professional to know how to lead the light into the bath according to all the rules. But everything is not as complicated as it seems at first glance, although the wiring device in the bath is significantly different from its device in less humid rooms.

Electricity enters the bath from the main, central shield, which distributes electricity. It is desirable to do wiring in those places where it is least noticeable.

In addition, there are several conditions that must be adhered to:

The voltage itself is best carried out through an RCD or AB.
The lighting of the steam room and the washing room must be powered through a second transformer. The supply voltage in these rooms should not exceed 12V and 36V, respectively.
The cable must be selected very carefully. It is best to opt for copper, in a special shell with a double layer of insulation. It is considered to be very resistant to high temperature and humidity.
A general switch is required.
Wiring must be done in a special pipe, preferably PVC. It is strongly not recommended to use metal sleeves, especially in washing and steam rooms.
Installation of sockets and switches in the steam room and washing is strictly prohibited.

Advice!
Carefully study the characteristics of fixtures before buying.
Their protection class must be at least IP-54.

Due to poor quality wires or poor-quality wiring, fires can occur.

If your bath is with a second light, then the choice of fixtures should be approached with great care. In this case, it is best to trust the opinion of a professional. Even if the price of a bath lighting project with a second light is high.

In any case, it is better to pay for the project than to change fixtures 2-3 times, and possibly wiring. Moreover, baths with a second light are considered very prestigious, since not everyone can afford such a luxury.

How should the lighting in the bath in different rooms look like?

It is very important to choose the right lamps for baths and saunas. After all, not every one of them will fit.

You need to understand that a bath is a room where safety should come first. And the choice of lamps plays an important role.

Lighting in the steam room

There are special requirements for lighting in the steam room, because. This is a room with high temperature and humidity. In addition, the soft semi-light in the steam room will help you relax and enjoy the bath procedures.

Luminaires are best installed in corners or.
LED lamps for a bath are rather responsible for the extraordinary look of the steam room. They are very resistant to high temperatures, therefore, they can even be installed on a fence.
All glass lamps must be hidden, with special gratings or heat-resistant platforms.

Advice!!!
Do not use fluorescent lamps in the steam room.
Due to the high temperature, they can cause an explosion.
And mercury vapor can be deadly.

Washroom lighting

There is no high temperature in the car wash, but the humidity remains. In the shower, we wash away the weight of the steam room.

Therefore, in this room, the lighting should be bright, because it is no longer intended for relaxation. Here they do not relax, but wash themselves.

Luminaires should be located as far as possible from damp places.
Even the most basic detail, such as a switch, should be outside the sink.
Light for a bath plays a very important role, but you should worry about safety more than about choosing beautiful lamps. All devices responsible for lighting must be covered with special shades.

In the dressing room, lighting can be anything. The temperature and humidity of this room allows you to attach both lamps and large lamps there. The brightness of the light depends only on your desire.

How to make unique lighting in the bath

A little imagination, and your bath can turn into a work of art. And this will help you install the right lighting lamps in the right places.

Lamps for steam rooms and saunas are not uncommon, and you can buy them in almost all stores. But, in order to create an indescribable light atmosphere in such a room, it is worth using LED lamps.

Such lighting has its advantages:

LED lighting for a bath is chosen, rather, to make the sauna extraordinary, to give it a special atmosphere. Such lighting is a guarantee of good mood and excellent rest.
In order for the rest in the bath to be effective, you need to achieve a balanced light. LED strip in the bath will help to achieve the desired result.
It is not at all difficult to conduct light of this kind. For this, there is no need to contact specialists. You can easily do everything with your own hands.
LEDs are safe and resistant to heat, so they can be placed just about anywhere. For example, on the ceiling, on the floor or on the walls.
Wiring instructions are not complicated. But in order to provide for emergency situations, it is better to seek help from a specialist.

If we compare ordinary lamps and LEDs, then their price is higher than usual, but the variety of colors and increased safety make them preferable.

High-quality light in the steam room has always played a very important role. Some think more about the beautiful interior of the sauna and its originality, while neglecting the safety rules. Of course, dim and high-quality lighting of the steam room is very important.

Summary

You can learn more about the correct installation of light in the bath by watching the video in this article. I would like to believe that this information will be useful to you, and our recommendations will help you make the right light in the bath.

A bathhouse is a building in which you can not only take water and health-improving hygiene procedures, but also an excellent place for complete psychological relaxation and physical relaxation.

Therefore, a well-designed electric light in the bath with your own hands will help you forget all everyday worries and troubles, and will also fulfill its intended purpose - it will illuminate the premises at night.

The main requirements for electrical wiring in the bath are as follows:

The location of all fittings (general switch, main group of sockets and other electrical switches) should be exclusively in the dressing room or rest room.
For safety reasons, it is not allowed to install electrical sockets, as well as switches in the steam room and washing room (shower room).
Modern residual current devices (RCD) or circuit breakers (AB) are also recommended to be installed in the dressing room.
Install in the steam room and washing room only hermetically sealed fixtures with special protection against high humidity.
The washing and steam room lighting should be powered through a second transformer with a voltage of no more than 12 V and 36 V.

Electrical wires must be packed in special corrugated PVC tubes to protect them from moisture.
Careful selection of lighting cable. As a rule, it is desirable to purchase material made of copper, in a special sheath with a double layer of insulation, since such a cable is considered to be very resistant to high temperatures and moisture.
Cables must be designed strictly in accordance with the PUE (chapter 7.1. "Electrical installations of residential buildings"), SNiP 2.08.01-89 and GOST R 50571.11-96.

To lead the light into the bath with your own hands, it is advisable to have the necessary knowledge for this regarding the installation of electrical wiring, otherwise the attempts made can end very badly.

Selection and installation of lighting devices in the bath

After the wiring of electrical cables around the entire perimeter of the bath is carried out and carried out in accordance with the designed scheme, you can safely proceed with the installation of lighting fixtures.

The light in the bath with your own hands entirely depends on the methodology of the chosen installation scheme, which today is mostly carried out using incandescent lamps. In some variants, LED and fiber optic luminaires can also be used. However, the installation of the latter requires the installation of auxiliary elements, moreover, such electrical equipment is quite expensive and therefore has not yet gained much popularity.

For example, in the hallway or dressing room, you can install wall sconces that are inconspicuous in design, or any other lighting devices in which the ceiling lamps have a maximum power of 75 to 100 watts. At the same time, for the convenience of adjusting the brightness of the light in the rest room, you can install a double switch, as well as use lamps equipped with two or more cartridges.

The other 2 rooms - a steam room and a shower room - require a different, special approach. In them, the space of the room from the inside should be well lit, but the lighting elements and wiring themselves are reliably protected from direct moisture (or condensation) on them.

At the same time, the shower room can be equipped with simply sealed shades, and it is better to place the wires and contacts in a place inaccessible to water splashes - the ceiling.

In this regard, for safety reasons, it is advisable to think over the circuit of electrical switches outside (outside) these two rooms, that is, install them for convenience, for example, next to the front door, but in the dressing room.

Specific recommendations for lighting in the steam room concern not only the moisture-proof function of the lamps, but also their ability to withstand high temperatures. Optimal and favorable light in a do-it-yourself bath, in particular, in a steam room, should be muffled, dim, and also with a power of no more than 60-75 watts. These parameters meet the requirements of the safety rules, since the increased power of incandescent bulbs in the steam room can lead to overheating of the shades, and too bright light will not give the desired relaxation and rest when taking procedures.

Taking into account all the above recommendations for lighting in the shower room and steam room, it is advisable to conduct low-voltage voltage (12 V) in these rooms, and also install a step-down transformer for this purpose, of course, outside this building, that is, on the street.

Electrification in the bath

Today, an electrified bath is not only a pair of electric lighting devices, but also a much more complicated functional system.

Thus, electrical supply, in addition to standard lighting in the steam room, makes it possible to equip other bath rooms with the following useful components:

Warm electric floors.
Washing machine and heat gun to dry all rooms.
Pump station and water heater.
Electrical measuring devices for humidity and temperature in the room.
Internal lighting in the pool and electric heater.
Spa equipment, infrared heaters, as well as an electric hairdryer and kettle, a plasma TV and even a mini-fridge for beer.

The light in the bath with your own hands should be thought out to the smallest detail: poor-quality wiring or defective products installed in the premises can lead to at least a fire, so carefully read the instructions for installing lighting fixtures.

A bathhouse is an ideal place to spend time in order to get positive emotions and have the most beneficial effect on the body, but it is not always safe when it comes to the frequency of fires that occur due to the fault of the owner who built or used the bathhouse incorrectly. The article will discuss how to conduct electrical wiring in the bath with your own hands, with all the nuances and individual characteristics of the stages of the procedure.

Basics of electrical installation in bath rooms

Naturally, a fire hazard arises in the bath primarily from the fact that the room is operated at high temperatures. But electrical wiring also plays an important role in this matter. It is necessary with all responsibility to approach the choice of electrical appliances, wiring and the correct installation. The basic standards that are prescribed in the set of rules for the installation of electrical installations (PUE) must be observed.

Without certain skills in working with electrical wiring, you should not even try to lay it on your own. If there is certain knowledge, then the wiring in the bathhouse and steam room can be installed qualitatively, taking into account all the information given below in the article. First of all, again, you should read the PUE, since all the necessary data on the required cables, electrical installations and devices are given there.

How should the power cable be connected to the bath

To organize electricity in the bath, it is necessary to deliver it via a power cable from the nearest source of electricity. There are two main methods: air and underground. It is faster and less costly, of course, to pull the cable through the air, but if we are talking about safety, then it is worth laying it at a depth.

If the air method is used, then the following standards must be met:

height above the road - 6 meters;
above pedestrian areas - from 3.5 meters;
if the distance from the nearest support to the bath is more than 25 meters, an intermediate support must be installed;
the height of the inlet for the cable going to the building is from 2.75 meters.

With a hinged installation method, a self-supporting insulating wire (SIP-4) is used without a supporting cable. The aluminum conductors of this cable have a cross section of 16 square meters. mm. The number of cores depends on how many phases the cable will be connected to. There is a two-phase version for 2 and a three-phase version for 4 cores.

When wiring is laid in the bath and steam room, SIP-4 cannot be used. Immediately behind the wall under the attic, it should be replaced by a VVG, NG or NYM type cable. As connectors between two types of cable, a sealed copper-aluminum adapter is used.

Bringing the cable to the wall of the bath, you can fix it on the outer wall of the building, having previously laid it in a corrugated tube or plastic cable channel. It is forbidden to enter the cable directly, therefore it should be carried out through a special box with a circuit breaker. The machine is also selected taking into account the number of connected phases for 2 or 4 lanes. SIP is supplied from the street side, and the necessary cable is connected already indoors.

The load threshold at which the machine operates must be higher than that of those that will be placed indoors. Through the wall, the cable must be laid along a metal tube with grounding. A rubber tube cannot be used in this case, because after a certain time of operation, the rubber loses its antistatic properties.

Another way to conduct electricity in a bath involves laying a power cable through a steel pipe. This is not only more reliable than simply hanging the cable, but also more aesthetically pleasing. In the photo and during visual inspection, the tube will look more aesthetically pleasing.

However, this method has a number of conditions:

the upper end of the pipe bends in the shape of a half ring so that moisture does not get inside;
the lower end is fixed so that it leans 5-15 degrees towards the street;
the surface of the pipe is painted, and a hole is drilled at its lowest point so that the condensed liquid flows out into the street;
fastening to the wall is carried out using clamps, and the upper end is hung on a steel stretch, fixed through bolts on the roof;
on the pipe must be attached (welded) insulated pins (covered with caps), on which the cable will be fixed with aluminum wire;
at the last stage, an introductory cable of the type provided for by the PUE is passed through the metal rack.

As for the underground laying method, it is first of all difficult and also expensive, but its advantages cannot be denied. The cable laid in this way is reliably protected from mechanical damage and its service life limit (until the next revision) is much longer.

The high cost of this method is due to the fact that a more expensive power cable of the VBbShv brand is used. It is impossible to use the above-described wire for saunas and baths (SIP 4), since this is prohibited by the PUE. Its advantage is that its shell is called armored because of the double shell with a metal braid between the layers. Copper shells are hidden inside and usually there are four of them with a cross section of 10 mm. sq. each.

Installation is carried out as follows:

A trench breaks out with a depth of 0.7-1.2 meters.
A layer of sand 10 centimeters thick is poured at the bottom.
Then the cable itself is laid and wakes up with sand.
A brick layer can be laid over the embankment, which will provide mechanical protection to the cable.
For vertical cable placement, metal tubes and corners should be used. They cannot be placed horizontally, since condensed moisture will accumulate in the cavities.
It is necessary to enter the cable by analogy with the air type of installation.

If the cable is laid in a trench, then a “snake” should be made so that there is a compensation margin, since seasonal soil movements can lead to cable tension.

Rules for drawing up a wiring diagram

According to the standard, the wiring diagram in the bath is drawn up by a specialist, since it is necessary to take into account the humidity and temperature conditions in the premises. There is no single principle according to which electrical wiring is laid in the bath rooms, since the buildings themselves have a different layout.

You can draw up a wiring diagram in the bath with your own hands, but there are no specific templates for it, and therefore you can only focus on the number of power plants that will consume the power of incoming electrical energy. When drawing up a diagram, you need to initially know what the connection will be like: single-phase or three-phase.

In fact, the laying principle for both options is similar, but the schemes will differ slightly:

single-phase connection implies that there will be only two wires at the input: phase and zero. In phase, the current is supplied to electrical appliances, the lighting system and other consumers. It returns to zero. Its maximum power is 14 kilowatts;
three-phase - these are four wires: three phases and one zero. The route for the current is similar, but in this case it enters through three wires at once, and returns at zero. Maximum power - 42 kilowatts.

The number of phases does not affect the basic rules for the placement of electrical system elements. Sockets and switches in showers (washing rooms) and steam rooms cannot be placed according to the rules of the PUE. Most often, a single-phase network is connected to the bath, but three phases are needed if more powerful heating devices are placed in the room.

A three-phase network has the following advantages:

the use of more powerful electrical appliances;
the use of three-phase sockets for powering boilers, heaters or electric stoves-heaters.

However, they also have disadvantages:

the total amount of consumed electrical energy is large, and therefore its cost will be high;
it is possible to bring a three-phase network only with the permission of the relevant control authorities;
the cost of electricity supplied through such a network is higher;
additional equipment will need to be installed on the switchboard, which will also increase the cost. The importance of this equipment is obvious as it is used to evenly distribute the current to all three phases. Only in this case, each wire will work under the same load.

As long as the electrical wiring is represented by a drawing in the form of a paper plan or a digital photo, it can still be corrected. On such a scheme, you can pre-apply the installation locations of electrical appliances in order to determine in advance not only their placement, but also the number, which will make it possible to determine the maximum load on the network. It will also be possible to determine the type of wire, its quantity and other network parameters.

Based on the fact that the main electrical appliances are used at a voltage of 12-36 volts. For the correct supply of electrical energy, they need to install a step-down transformer for the bath, which allows you to distribute current with three types of voltage: 12, 18 and 36 volts. It is desirable to apply the same voltage to lighting fixtures in the steam room and washing room in order to increase safety, although this will increase the cost of wiring.

The project should also indicate the installation locations of residual current devices and differential circuit breakers. The advantage of the latter over conventional machines is that they deactivate the system even with a normal touch on the exposed section of the wire. The current supply stops in 25-40 milliseconds, which is enough to protect a person from electric shock.

When the wiring diagram of the bath is drawn up, it is worth giving it to a specialist for verification. It should clearly indicate not only the locations of all functional elements, but even the ways they are connected to each other.

According to the approved scheme, installation must be carried out without a single error and in compliance with all the indicated parameters. Only in this case will an efficient, reliable and maximally safe system for supplying electrical energy to the bath be obtained.

Stage of calculations and preparation for the start of installation work

After the wiring for the bath and sauna is presented in the form of a diagram, and all the parameters and features of the connections are taken into account, it is necessary to begin the calculation stage. At this stage, the sections are selected that each cable for the bath in the steam room and other rooms will have. Then the parameters of circuit breakers and sockets are selected.

It is possible to determine the cross section of the cables that will make up the electrical wiring in a log cabin or brick building only after the planned maximum load on this very system is known. To do this, you need to study the documentation of all electrical appliances that you plan to use in the bath.

In documents, you need to look for the parameter of their power in watts and kilowatts, and then get the total value. When choosing the cable cross-section and the maximum load on the system, you need to calculate with a margin of 20-25%, even taking into account those devices that will be used extremely rarely.

Once the system load limit has been determined (the value must be in watts) it must be divided by the line voltage value (in volts). The resulting value (in amperes) is the current strength in the network. According to this parameter, the cable section is selected, through which wiring will be organized in the steam room and other rooms of the bath.

The cable section is selected with emphasis on the current strength, because if the values \u200b\u200bof these two parameters do not match, the cable will overheat. The consequence may be the ignition of the cable with the spread of fire throughout the bath.

The parameters are selected as follows:

16 amperes - 1.5 sq. mm;
25 amps - 2.5 sq. mm;
32 amps - 4 sq. mm;
40 amps - 6 km. mm.

If desired, you can opt out of this ratio. The easiest way is to add 1 sq. m. for every 2 kilowatts of power. mm to the cable section.

The above values were selected for cables with copper conductors. If we are talking about how to conduct wiring in a bath, then only cables with copper conductors can be used indoors. Aluminum cores are extremely unsafe to use due to the high risk of fire and short circuit.

Even in the buildings of the last century, today aluminum cables are being actively replaced with copper ones. To increase the safety of copper wiring, the cross section of the cables should be increased relative to what was calculated. In this case, by spending a little more money, you can make a margin for connecting additional electrical appliances.

When choosing the cross section of wires for individual lines of an electrical network, it is worth using the same principle. According to the cable standard of 4 sq. mm. section is enough to supply electric current to the switchboard, and 2.5 sq. mm. – can be used to connect other elements. Of course, for more powerful electrical appliances, you need to increase the cross section to at least 4 sq. Mm.

During installation, it is necessary to follow the rules for connecting cables: a smaller section to a larger section. If you do not follow the rule, then in places of incorrect connection, excessive heating of the cable may occur, which is a direct violation of fire safety.

After the cable sections have been determined, it is necessary to select the most optimal machines that will be safe and rational in operation. The most powerful automaton is installed at the beginning of the chain for general control of it. Weaker settings are used on circuit lines.

The power of the machine is calculated according to the same scheme as the cross section of the power cables. For example, if a value of 20 amperes was calculated, then the installation must withstand at least 25 amperes, and even better - 32 amperes. The maximum load of linear automata is selected in accordance with the load of the weakest device connected to the line. For example, if the line feeds only one 60-watt light bulb, then a 25-amp machine is simply not needed for it.

In the bath, the humidity regime is unacceptable for using the electrical network without a residual current device (RCD). The installation is provided for use by the rules of the PUE. According to the standards of the PUE, it is necessary that the value of the installation power of 10-16 milliamps be achieved.

However, more powerful devices (25-30 milliamps) should be installed, since at lower values there is a high risk of emergency operation with or without reason. Accordingly, it is necessary to choose an RCD taking into account the norms given in the PUE and the recommendations of a specialist.

Procurement of cables and electrical equipment before the start of installation work

If we are talking about how to properly conduct the wiring in the bath, then all equipment and cables must have a high level of protection from exposure to high humidity and temperature. Usually equipment and materials for such environments are rated IP24, which protects the system from the effects of particles as large as 1.25 centimeters, as well as splashing water.

Cables in the bath rooms must meet certain requirements when it comes to the steam room and washing room.

PVKV;
PRCA;
PRKS;
RKGM (multiwire);
PMTK;
OLFLEX HEAT 205 (single or stranded).

Each of these cables can easily withstand the humidity and temperature load of 180 degrees Celsius. If we are talking about how to make electrical wiring in the bath (in the rest room, vestibule), then you can use the standard VVGng-LS or NYM cable. Again, it is worth recalling that you need to make a choice in favor of copper cables. Their ultimate load and resistance to mechanical stress is much higher.

It should be noted that it is strictly forbidden to use PUNP cables. Moreover, it is neither suitable not only for a bath, but also for living quarters in a house. Its main disadvantage is that the thickness of the cores in it may have errors made at the production stage.

Most often, the cable according to the documents has a cross section of 2.5 sq. mm., And in fact - 1.75 sq. mm. Accordingly, it may overheat and cause a fire. When it comes to how to do the wiring in the bath correctly, it is unacceptable to save on cables, and PUNP and PUGNP have only a domestic purpose.

Protective automatic shutdown systems (RCD, automata and differential automaton), taking into account the load that will be placed on the power grid as a whole and on each of its branches separately. Each of the installations must be marked on the diagram with the parameters for them.

A feature of the operation of such installations is their automatic response to certain parameters of the electric current in the network. The sensitivity of the installation to overload can be of different classes: from A to D. The corresponding marking is applied to the circuit breaker body.

Individual characteristics:

Class A- has the highest sensitivity. Such installations are used in conditions when a power outage is required to be carried out in a matter of milliseconds and they are almost never used in everyday life.
Class B– suitable for those cases when the main used devices can be used in conditions of increased load for some time.
Class C- the most popular installations for living conditions. The machine does not immediately respond to an overload, but turns off the electricity supply only in case of serious violations in the system. For example, during a short circuit.
Class D- mounted on the main line through which electrical energy is supplied to the building. Perform such installations of the ruble duplicating in order to turn off the supply of electrical energy in the event of a failure of class C machines.

If we are talking about how to hold the light in the bath with your own hands, then all lighting fixtures and sockets should be selected taking into account the level of security (according to GOST, there should be an IP-44 or IP-65 value). Complete with sockets, rubber seals must be present.

All lamps must be protected from moisture. The body of the luminaire must be made of materials that are not subject to the effect of corrosion, and the lamp itself must be made of heat-resistant glass with increased strength.

It is not allowed to use plastic elements and fluorescent lamps, which simply explode under the influence of temperature, due to which gases harmful to the human body are released. It is best to use a fiber optic lighting system that is not afraid of exposure to high temperature and humidity.

In the washing room and the rest room, it is necessary to install LED lamps that have sufficient power and at the same time save electrical energy perfectly. The advantage of LED lighting fixtures is that they have a voltage of 3 to 12 volts.

If we are talking about how to bring light into the bathhouse from home, then LED lighting is ideal for this task and will create a minimum load on the electrical network of a residential building (read also: "How to properly make lighting in a sauna in a steam room - practical advice").

After drawing up the wiring diagram in the bath and preparing for installation is completed, you can begin to work. It is important to treat the process with all caution and paying as much attention to any details as possible.

You can do the installation of electrical wiring with your own hands, but it is strictly forbidden to make even minimal mistakes. To create the most efficient and safe electrical network, it is necessary to be guided by the latest edition of the EMP. Without reading this set of rules, it is strictly forbidden to start installation.

In the bath, the installation of electrical wiring is best done in an open way, which is listed in the PUE only as an acceptable possibility. In practice, it has been proven that this method is safe and very convenient. In a hidden way, you can install only those electrical wiring lines that power the lighting system. This is far from being a hidden installation under the sheathing material, but only about passing the cable through the wall along a metal tube. The advantage of surface placement of cables is obvious: they are easier to repair in case of damage.

The wiring is fixed with an open installation method using porcelain insulators, brackets and cable trays. It is possible to reduce the areas where the cable will be exposed by placing it in a corrugated tube, a European skirting board or a plastic cable channel. And the placement of the electrical network line in this way increases its aesthetics.

In the case of using porcelain insulators, it is worth fixing them on logs with an interval of no more than 40 centimeters in a horizontal plane. When placing the cable vertically, a minimum of 2 fasteners should be used, even if the length of the cable in this section is very short. In the latter case, the cable should be fixed by placing fasteners at the ends of the section.

The distribution panel from the electrical network is a defining element, since it is in it that the main protective devices (circuit breakers, RCDs, voltage reduction transformers, etc.) will be placed. Accordingly, it is necessary to mount the shield using high-quality materials, the intended purpose of which is the function of electrical installation.

First of all, we are talking about the fact that high humidity does not have an excessive effect on this element of the network. The installation of the shield should be carried out at the maximum distance from the steam room and shower room. Best of all at the entrance to the bath.

An experienced electrician will sign each circuit breaker and other devices in the shield to facilitate ease of operation and repair work. Also, in the shield you need to place a detailed diagram of the electrical wiring in the bath in order to visualize information about the system for the person who will carry out the repair.

Each cable entering and leaving the junction box must be enclosed in a corrugated plastic tube or cable channel. The cores of the wires must be securely fastened to the terminals of electrical installations, since otherwise heating will occur at the junctions of the wire and the installation, followed by burning of a poorly fixed core.

All conductors acting as a phase and connected to devices that create a load must be fixed at the bottom of the machines. The switchboard must be properly grounded.

Again, it is worth repeating that it is strictly forbidden to place sockets, switches and junction boxes in steam rooms and a sauna. Each of the listed functional elements of the electrical network must be installed in the dressing room, or in the rest room.

But at the same time, they must still have a category of products that are acceptable for use in a room with a high humidity level. We are talking about a level of protection not lower than IP-44 (covers must be installed on each socket and switch).

Each connection cable in the system should be as short as possible. Each electrical appliance must be grounded so that the level of safety of operation of the electrical network is maximum.

Each wire that connects electrical appliances must be insulated with non-combustible material and in no case should pipes or metal boxes be used. The pipe can only be installed as a sheath when the wire passes through the wall. You can not twist the wires in the bath with each other.

Cables can only be connected by soldering, or through reliable terminals. The ideal system is one in which all cables from the switchboard are solid.

The cable can only be laid horizontally or vertically, and when bending it, a right angle must be observed. The number of wires in this case should be minimal, as well as the number of other electrical appliances and system elements.

Outcome

The article deals with how to conduct high-quality electrical wiring in the bath. All norms, rules and recommendations given in the article must be observed during the installation process. It is best to carefully study the set of standards for PUE.

However, we can talk about safety only when all the wiring work is carried out by a specialist who will take responsibility for all stages - from purchasing the necessary materials to installing the system and putting it into operation.

Wiring in a room with high humidity requires a special approach. If there are no skills and knowledge in the field of electric power industry, then it is better for professionals to do the work. Even a simple scheme must be assembled from special materials and according to all the rules. It's not scary that the system can close in a wet bath, but an improperly executed electrical system can kill a wet person. How to make wiring in the bath according to all the rules and what mistakes are made, we will talk in this article.

Wiring in the bath made by professionals.

Safety first!

It is necessary to install the wiring in the bath in accordance with the requirements of the PUE (rules for electrical installations). Rules for wet and dangerous buildings have their own regulations. According to the documentation, fittings can only be placed in the dressing room, the steam room and the washing department are not intended for such nodes. All lamps must be under protective covers, and not simple ones, but with tight connections.

It is better if the wiring in the bath is done by professionals, but if you have knowledge in this area, you can do everything yourself.

Wiring in the bath can be done according to a simple scheme. Modern designs are multifunctional, so the power supply circuit is mounted complex. In such a bath can be located: lamps, an electric oven, a moisture meter and a temperature sensor, infrared or awning warm floors, sockets for a TV, a hairdryer, a refrigerator. In addition to everything listed in modern designs, there can be a pool with lighting, a pumping station, and a heat gun.

Why is incorrect wiring dangerous?

Steam is dangerous in the bath, as it consists of particles of water, which is an excellent electrical conductor. Therefore, if you install a socket or switch in places where steam is accessible, condensate will settle on the elements and a fire or short circuit may occur. Before installing the wiring, specialists will make the necessary calculations and draw up a diagram that cannot be performed without knowledge. Services are not cheap, so in most cases they perform the system on their own. But this must be done in accordance with all rules and regulations.

Installation of sockets and switches in the bath is easier to do with a special nozzle on the drill.

Before installation, it is necessary to draw a diagram where all nodes (sockets, switches, branching boxes) will be drawn. At the same time, it is worth considering in advance what and where will be connected. Only after that the total power of all sources is calculated and it is determined which cable, section and size is needed.

Rules and regulations for the placement of the electrical system in baths

For a bath, wiring is carried out in a separate line from the main switchboard. This is done in order to protect the owners and create a separate ground loop. Wiring should not be conspicuous and does not fit in the corners, opposite the doorways. To the centers of heating: stoves, pipes, generators is located no closer than 1.5 m.

Electrical wiring in the bath can be mounted in two ways:

Hidden: used in brick or block baths, unacceptable in wooden ones. It is carried out in special slotted channels with additional asbestos insulation.
Open: wiring is allowed directly along the wall, used in wooden structures.

Wiring is carried out according to several basic rules:

Power is passed through an AB or a residual current device (RCD), and light is passed into the steam room or into the washing room through a step-down transformer.
For wiring, it is better to use a copper non-burning cable of the VVGngLS 3x2.5 type.
All the main elements: electrical panel, current distribution box, central switch are mounted only in the dressing room.
For a wooden bath, they throw the wiring from the room into the neighboring one through a drilled hole right in the wall. A ½ inch metal tube is inserted into it for safety. In no case should you drill a hole at the joints and seams, only in the middle of the link.
It is necessary to isolate the wiring using a special corrugation made of plastic or metal. It will not allow the system to ignite, and if damaged, the rock will simply melt. Under all sockets and switches, a metal or asbestos plate is also mounted.
Wiring in wooden structures cannot be hidden in transitional ceilings and under the floor, the entire system must be open. For greater security, asbestos material can be attached to the bottom of the wall.
It is necessary to connect the wires to each other using terminals; it is unacceptable to twist the wiring.

Also, do not use vinyl or rubberized wiring in the bath. It is optimal to use corrugated H07RN-F, VVGng-LS 3x1.5.

How to run the cable to the bath

Wiring put into the bathhouse not through a through hole in the log is considered incorrect.

If the bath is located in close proximity to the main house, then there will be no problem. It will be more difficult to throw the wire on a separate bath. In such cases, it is necessary to install the power wire to the bath from the main electrical panel.

According to the installation method, there are two ways to bring the electric wire to the bath: ground and air. Air conduction is more accessible, since for work you just need to put additional supports in the form of pillars. For the line, a SIP cable (self-supporting insulated wire) is taken. It can be tensioned without additional construction of cables, and the service life is more than 20 years.

SIP is thrown over the poles to the bathhouse and injected inside through a special hole with a metal pipe or asbestos insulator.

The ground method of pulling the electric wire to the bath is more complicated and requires material and physical costs. But on the other hand, the line will not be visible and the landscape will not have to be spoiled by pillars. For installation, they take a copper durable cable VBbShv 3x2.5, armored. It is acceptable to use not armored, but then it will be more vulnerable and it is hidden in a special protective metal pipe. The cable is buried at least 700 mm deep, and the laying points are marked, for example, with bricks or decorative stone. This is necessary to simplify the search for possible damage or replacement.

When the wire is connected, it is necessary to correctly install the shield.

How to properly mount the shield

The first thing to do is to choose the right place for the electrical panel. The main rules to be followed are:

The electrical panel is placed in a dry and ventilated place. The accumulation of condensate on the internal parts of the structure is unacceptable.
Access to the electrical panel must always be available.
The place should not be darkened, it is better if natural light enters the shield.
The top of the box should be at least 150-180 cm from the floor.
If the wiring is single-phase, then a three-core cable will do.

What to consider when drawing up an electrical system diagram

The wiring in the bath must be in special insulation.

When drawing up a wiring diagram for a bath, the location of electrical appliances and other components is taken into account. They can only be installed in dry rooms. This is due to fire safety rules and the fact that less corrosion will form on the parts. If the device is plastic, then its mechanism still has metal parts.

There are devices on which protection is installed by manufacturers, so they can be safely placed in the washing room. These include modern showers, bathtubs with massage systems, spa equipment and more. other.

Light fixtures for the steam room can only be used on a metal base with a protective glass structure. Lamps are mounted on the walls, stepping back from the ceiling by 20 cm.

The transformer conducting the electrical system to the bath does not exceed 220 volts. In the steam room, the washing compartment can be distributed 12 volts, which are carried through the wall. This is somewhat different from the PUE standards, which say that 42 volts is permissible in dangerous places in the structure. But this is taking into account a light bulb of 36 volts, and in most modern designs these are not used.

If a washing machine or dishwasher is located in the bath, then a separate socket with grounding should be brought under them. They can only be installed in a dry place. If a tank is used for heating hot water, then a separate wire is laid that goes separately from the general system.

Protective automatic RCD

A grounding system loop is mounted along the perimeter of the structure. The system is equipped with an RCD emergency shutdown machine, or a differential system. If the installation of automation is impossible for any reason, then T220/12 is mounted. All protective devices must be hidden in a waterproof box.

Electric heater in the power supply system

Sensors for electric heaters in saunas can only be used at low voltage. They are mounted on the surface of the wall, which is located farthest from the heater. Choose a suitable place and measure 1 m from the floor to proceed with the installation. It is forbidden to mount the control panel for sensors in the steam room.

The electric heater is connected separately from the main system, without sockets. To do this, a separate cable is thrown from the shield, which is connected to the heat generator and a separate ground is made.

Conduct wiring to the electric heater and light bulbs in the steam room should be no closer than 0.8 m from the chimney and stove. At the same time, it should not bend or twist anywhere, only one-piece in a special corrugation.

Bath lamps

Each electrical unit should be located on the wall, in no case should they be hidden inside the tree.

You should not use simple paws for washing and steam room. Luminescence is taken only with protection in IP44 degree. Among the safest, it is worth highlighting 12 volt halogen lamps.

It is better to use wiring for a steam room from a heat-resistant material, for example, the SILFLEX Sif brand, single-core with special silicone insulation.

In some modern schemes, the light in the steam room is made from below, so there will be less heating. The lighting looks attractive, as it is carried out by spotlights, for example, built into the lower step of the canopy.

Inside the canopy structure, the wiring is additionally insulated in metal pipes.

You need to check the wiring every 2-3 years, preferably more often. The shelf life of the wiring should also be taken into account: copper - up to 20 years, aluminum up to 15 years. And since the humidity and elevated temperatures in the baths affect the wiring aggressively, you can safely divide the numbers by 2 and change the wiring completely after the expiration date.

Even by hiring a professional, you should not let things take their course, you need to control the entire process from and to. Only in this way the wiring in the bath will be safe and will last the prescribed period.

How to make light in the bath

It is enough to apply a little imagination to skillful hands and the lamps in your bath will become not just utilitarian lighting, but will be integral elements of the design of the room.

How to conduct electricity in the bath

Electricity enters the bath from the main, central shield, which distributes electricity. It is desirable to do wiring in those places where it is least noticeable.

In addition, there are several conditions that must be adhered to:

The voltage itself is best carried out through an RCD or AB.
The lighting of the steam room and the washing room must be powered through a second transformer. The supply voltage in these rooms should not exceed 12V and 36V, respectively.
The cable must be selected very carefully. It is best to opt for copper, in a special shell with a double layer of insulation. It is considered to be very resistant to high temperature and humidity.
The general switch must be installed in the dressing room.
Wiring must be done in a special pipe, preferably PVC. It is strongly not recommended to use metal sleeves, especially in washing and steam rooms.
Installation of sockets and switches in the steam room and washing is strictly prohibited.

Advice!
Carefully study the characteristics of fixtures before buying.
Their protection class must be at least IP-54.

Due to poor quality wires or poor-quality wiring, fires can occur.

How should the lighting in the bath in different rooms look like?

It is very important to choose the right lamps for baths and saunas. After all, not every one of them will fit.

You need to understand that a bath is a room where safety should come first. And the choice of lamps plays an important role.

Lighting in the steam room

Lamps are best installed in the corners or directly under the ceiling of the bath.
LED lamps for a bath are rather responsible for the extraordinary look of the steam room. They are very resistant to high temperatures, therefore, they can be installed even on the fence around the sauna heater.
All glass lamps must be hidden, with special gratings or heat-resistant platforms.

Advice!!!
Do not use fluorescent lamps in the steam room.
Due to the high temperature, they can cause an explosion.
And mercury vapor can be deadly.

Washroom lighting

There is no high temperature in the car wash, but the humidity remains. In the shower, we wash away the weight of the steam room.

Therefore, in this room, the lighting should be bright, because it is no longer intended for relaxation. Here they do not relax, but wash themselves.

Luminaires should be located as far as possible from damp places.
Even the most basic detail, such as a switch, should be outside the sink.
Light for a bath plays a very important role, but you should worry about safety more than about choosing beautiful lamps. All devices responsible for lighting must be covered with special shades.

How to make unique lighting in the bath

A little imagination, and your bath can turn into a work of art. And this will help you install the right lighting lamps in the right places.

Lamps for steam rooms and saunas are not uncommon, and you can buy them in almost all stores. But, in order to create an indescribable light atmosphere in such a room, it is worth using LED lamps.

Such lighting has its advantages:

LED lighting for a bath is chosen, rather, to make the sauna extraordinary, to give it a special atmosphere. Such lighting is a guarantee of good mood and excellent rest.
In order for the rest in the bath to be effective, you need to achieve a balanced light. LED strip in the bath will help to achieve the desired result.
It is not at all difficult to conduct light of this kind. For this, there is no need to contact specialists. You can easily do everything with your own hands.
LEDs are safe and resistant to heat, so they can be placed just about anywhere. For example, on the ceiling, on the floor or on the walls.
Wiring instructions are not complicated. But in order to provide for emergency situations, it is better to seek help from a specialist.

If we compare ordinary lamps and LEDs, then their price is higher than usual, but the variety of colors and increased safety make them preferable.

Summary

How to independently make electrical wiring in the steam room?

Wiring in the bath is a necessary system that requires special attention and caution, since the environment here is too “aggressive” for its operation. When designing and installing the electrical system, the main negative factors of the room should be taken into account - high humidity and high temperature. A wooden bathhouse will require special close attention, since the risk of fire here increases many times over. So that the rest is not overshadowed by such troubles, it is worth initially responsibly approaching the creation of high-quality and workable wiring.

To conduct electricity in the bath, it is not at all necessary to seek the help of an electrician; wiring in the bath with your own hands is not at all difficult. The basic rule that everyone must adhere to is the use of high-quality equipment and consumables, as well as compliance with safety regulations. All work can be divided into several main stages:

Calculation of power and choice of wires.
Cable entry.
Installation of the shield in the bath.
Cable routing from the shield.
Connecting electrical appliances and installing sockets.

Power calculation and wire selection

At the very beginning, you should calculate the approximate power, based on the load on the electrical wiring in the bath. To make such calculations, you just need to add up on a sheet of paper the total amount of power of all devices that are supposed to be used. This indicator is indicated on the body of a particular equipment.

If you are not going to clutter up the room and limit yourself to light bulbs, then 1-2 kW will be enough. Thus, adding up all the data, you can calculate the cross section of the wires that will be used in the wiring. Subsequent calculations will also not create any particular difficulties: for every 2 kW of power, 1 mm2 of wire section will be required. That is, for 6 kW you will need a 3 mm2 wire, etc.

Due to the fire hazard of the facility, all wires must be double insulated. The most suitable sauna cables have two layers of rubber insulation. It is also recommended to purchase modifications with copper wire and with a protective waterproof sheath. Thus, we can distinguish several types of consumables that meet all the requirements and are ideal for conducting electrical wiring in such a room: PRN, APRN, PRVD, APV, PV, APPV and PPV. To connect lighting, VVGng-LS 3x1.5 is suitable. In addition, you will need to purchase PVC tubes in which the cable will be laid in the bath. If the wiring will be laid on a wooden plane, then it is recommended to lay sheet asbestos 3 mm thick under the PVC pipe. The specified material should protrude approximately 1 cm on each side.

The main characteristics of the temperature regime and air humidity in the baths:

High humidity and high temperatures can equally affect the condition of the electrical wiring and create a fire hazard.

What you need to know before you start wiring

Familiarize yourself with the Rules for the installation of electrical installations (PUE). The 7th edition of this document is valid on the territory of Russia.

In these Rules, in section 7, you will find clear requirements for the installation of electrical wiring and electrical appliances in rooms with high humidity and temperature.

Draw a wiring diagram in the bath and decide where and what equipment will be installed in the bath, where and what lamps, sockets, switches will be installed, which wires and how many of them in footage you will need for outdoor and indoor wiring. The choice of wire section depends on the number of electrical equipment and lighting fixtures.

Study the issue of grounding a detached building and also have information about the local power grid, since our networks did not previously provide for grounding in each individual house.

Preliminary preparation

Requirements

All cables are laid only in strictly horizontal or vertical directions.

The angles of the wires are laid only at a right angle (90 degrees).

The horizontal wiring line can be located no closer than 10-20 cm from the ceiling and must run parallel to it.

The distance of the wires from the doors must be more than 10 cm. The same applies to the switches near the window.

From metal objects, batteries, wires should be laid at a distance of no closer than 50 cm.

Switches can be located at a height of up to 1 meter from the floor surface.

European standard sockets are located at a distance of 30 cm from the floor level.

From the door of the shower cabin, sockets and switches can be located no closer than 60 cm.

The cabling from the switchboard is made with a single piece of cable.

Wiring can only be connected in a junction (junction) box, which has a high degree of protection against moisture and dust.

The electrical panel is mounted as close as possible to the input of the supply cable.

Forbidden

Lay wires against doorways and in the corners of walls.

Connect more than two lamps to one switch.

No bending or twisting of wires is allowed.

Wire twisting is not allowed - wire connections can only be made using soldering, welding, screw or bolt clamps and terminals.

Hide and hide junction (junction) boxes.

Before starting installation, draw on the walls with a pencil the main cable routes (by level) and mark the points of equipment, lamps, switches, sockets.

Save the electrical network diagram on paper in case you have to do repairs in the future

Features of connecting electrical wiring in baths and saunas

Conducting electrical wiring in places of increased risk of electric shock and fire safety, such as a bath or sauna, requires special rules.

Mandatory conditions

In terms of wiring:

It is necessary to stretch a separate, independent line for the supply of electricity from the main switchboard with a separate circuit breaker, and also mount a separate ground loop.

According to the requirements of the PUE, a hidden wiring system should be used, while open wiring is allowed. Open wiring is allowed in the wooden walls of the bath, that is, the wires can be led along the surface of the walls, and therefore it is better to place them in less noticeable places. In brick walls, electrical wiring should be hidden, that is, pass behind a layer of plaster.

Electrical wires must not touch wood walls or wood trim directly. Therefore, wiring is carried out in closed boxes or on a refractory surface (route). To do this, under any electrical equipment, sockets and switches, special heat-resistant linings made of ceramics or aceid sheets, or asbestos strips (at least 3 mm thick and 10 mm protrusion over the cable on both sides) are placed, which serve as an excellent insulating material. A route is mounted from a heat-resistant material that does not conduct current. It is necessary to calculate the distance between objects in advance in order to strengthen the insulators at approximately the same distance from each other. On log walls along horizontal lines, insulators are mounted along the log at a distance of 35-40 cm from each other. Insulators are installed along the vertical lines for installing electrical appliances, two for each log. The insulators are screwed with self-tapping screws using a screwdriver at an angle of 45 degrees up and down.

In terms of instruments and equipment:

RCD (residual current device) in the switchboard is a prerequisite for the application. The task of the RCD is to compare the current passing in phase and zero. And if the difference between these values \u200b\u200bis more than the limiting threshold of the RCD (that is, current leakage occurs), then the RCD will automatically turn off the phase and zero. For baths, an RCD of 5-10mA is used.

Sockets in the bath must withstand a load of 10-16 A, be splash-proof, with covers, protection class IP-44 and higher. The same applies to switches, junction boxes and fixtures.

Electrical equipment may only be used specifically designed for use in rooms with high humidity. It is better to place all equipment not built into the electric heater outside the saunas.

if it is placed in the steam room, then the PUE insists on the use of a temperature limiter, due to which, when the temperature reaches 140 degrees, the electric furnace will be disconnected from the voltage.

can be installed in the washing room, in the corner, closer to the door or in the dressing room. If you are going to install a stove, then it must be positioned in such a way that the chimney is as small as possible along the length, and it must also be protected with heat-resistant railings to prevent fire.

for a steam room should be with a wooden lampshade, a heat-resistant, moisture-proof shade and a ceramic cartridge. The metal parts of the fixtures must be grounded. In the sink, any lamp designed for bathrooms is suitable. The operating voltage should not exceed 24 volts in fixtures.

should be connected to the cable immediately after it exits the wall or ceiling, in order to minimize the passage of wires along the walls in the steam room and washing room.

Forbidden

In terms of wiring:

It is not allowed to twist, break and connect wires in the washing and steam rooms.

It is not allowed to conduct cables in metal pipes, sleeves or with metal sheaths, as well as on tin surfaces.

In terms of instruments and equipment

Plug sockets, switches and junction boxes are not allowed to be installed in the steam room, washing rooms and in rooms containing heaters for baths and saunas, they are installed in the dressing room or in the rest room.

It is also better to place the electric heater in another room.

Types of electrical wiring - advantages, disadvantages

Installation of electrical wiring in the bath can be done in two ways:

open (overhead)

hidden (internal)

Open installation of electrical networks provides for laying wires in:

steel boxes (cable channels),

corrugated sleeve

electrical skirting boards.

Reference:

The box is a construction of a square, triangular or rectangular type, with a flat base, inside which all the cables in the room are laid. Open type boxes are called trays. Cable channels are made of special non-flammable materials.

Wiring is laid over:

ceilings

For this purpose are used:

insulators

Important!

No connections or damage to the wires are allowed inside the pipelines. Cable channels can be filled with wires by no more than 60% in order to exclude overheating of communications and, accordingly, the danger of a short circuit.

Advantages

Installation is cheaper, since wall chasing is excluded

Repair work is simplified

disadvantages

Unaesthetic appearance

Wiring in cable channels along wooden structures can lead to deformation of plastic boxes over time.

It is difficult to lay a corrugated pipe perfectly evenly and it accumulates dust.

Hidden installation of electrical wiring provides for the laying of cables in closed boxes inside the structure of the building:

in the ceiling
in floors
in grooves under plaster
under the removable floor
inside building structures.

In this case, close attention should be paid to the joints of the cables, in particular, their insulation. And if the structure of the building is made of wood, then be sure to put insulating material on top and bottom of the wire.

Advantages of hidden wiring:

Fireproof and protected from moisture, since the access of air and moisture to the wires is significantly limited

Safe in terms of accidental contact with current-carrying conductors

The service life is higher than that of open wiring, since any mechanical damage is excluded

Aesthetic appearance

Disadvantages of concealed wiring:

Limited access to wiring, in case of troubleshooting

Labor-intensive installation

Types of wires for a bath

For overhead wiring, the most reliable wire today is SIP (self-supporting insulated wire), which is connected at one end to the main, and at the other - to the input structure on the wall of the structure.

Reference

SIP is a phase, neutral and additional wires twisted into a bundle, does not need a carrier cable and is mounted to supports or to the wall of buildings using linear fittings (anchor clamps). The minimum cross section is 16 sq. mm. A wire with such a cross section passes current up to 63 A.

For a bath, according to the requirements of the PUE, the wire cross section should not be less than 16 sq. Mm, and a larger cross section for a bath is useless.

Advantages of SIP

The wires do not overlap, which means that a short circuit is excluded

In winter, no ice crust forms on the wires

It has a special weatherproof coating that is resistant to atmospheric temperature changes. Such a wire is important to use on the coast of the sea.

Wires are not recyclable, therefore theft is excluded

Ease of installation work due to the presence of special clamps

High mechanical strength, which eliminates line breaks

SIP can be laid on the facades of buildings

SIP can be laid in joint suspension with communication lines and high and low voltage wires, which can save on supports.

Their service life is more than 25 years

Disadvantages of SIP

Compared to bare wires, which can be found everywhere in the private sector, the cost of laying SIPs increases by about 20%. The cost of SIP with a cross section of 16 sq. mm ranges from 20-30 rubles per linear meter.

Lack of flexibility, they are difficult to enter into the circuit breaker.

For underground wiring, an armored power cable with copper conductors of the brand - VBbShv and VBbShvng is used.

Advantages of VBbShv

The VBbShv brand cable is very reliable due to the use of a steel braid in it.

The cable is not threatened by earth shrinkage

Cable is not afraid of rodents

Disadvantages of VBbShv

high cost, which ranges from 200 rubles / m.

For indoor premises (but not in the steam room), wires are used - such as NYM, VVG.

For lighting devices, you can use the VVGng-LS cable with a cross section of 3x1.5

For the steam room and electric oven, a special cable with the most heat-resistant insulation that can withstand temperatures up to 180 degrees and high power consumption, with copper conductors (aluminum wires cannot be used in the bath) should be used.

These include wires of the PMTK, PRKA, RKGM, PGRK or PRKS brands. To the mounting box, which should be located outside the high temperature area, you lead one of the proposed heat-resistant wires, and you can run a VVG or NYM type cable from the box to the shield.

In a wooden bath, it is possible to lay wire of the APRN, PRN, AVRN, PRHD brands with double insulation. If there is single-phase electrical wiring in a wooden bath, then the supply cable must have three cores. You can also use wire brands APV, PV, APPV and PPV

Advantages

Wires of the VVG and NYM brands are designed for a maximum temperature of up to 70 degrees.

They don't support combustion.

Resistant to oxidative processes

Important!

For a bath, all cables must have:

double insulated, rubber-in-rubber insulation is ideal

be copper if intended for internal wiring

protected by waterproof shells

be three-core so that it is possible to ground appliances and sockets.

Electrical wiring inside the bath

Wiring is carried out at the bottom of the wall frame. The input of the wire into the sockets, the switches must be made from below or from the side, making a V-shaped knee (loop) so that condensate does not penetrate inside.

Insert the cable into the steam room through the wall or ceiling in the place where the lamp will be located. The free ends of the wires must be of sufficient length for the free connection of fixtures.

The metal parts of electrical appliances installed in steam rooms and washing rooms must be grounded. To do this, use a three-core cable, two wires from which are connected to phase and zero, and the third wire is grounded, connecting it to the fittings and leading to a house shield or to an introductory box on the site and connecting it to neutral.

All sockets must be protected by differential circuit breakers, and in rooms with high humidity, an RCD with a trip current of 10 mA must be installed.

In the rest room, all wires, without connections and any splices, are led to the shield.

The shield is proposed to be placed either in the rest room or in the vestibule. All wires coming from sockets, switches, introductory machines are connected on the shield.

Wiring device outside

There are two ways to bring electricity to the bath:

air

underground

Air mounting method

The air installation method provides for laying the wire from the switchboard to the bath building through the air and has certain height requirements.

Above the carriageway, the wire must be located at a height of at least 6 meters above ground level.

Above the pedestrian part - not less than 3.5 meters.

The cable must enter the structure of the bath at a height of at least 2.75 meters from the ground.

If the air distance from the highway to the house is more than 25 meters, it is necessary to install an additional support.

Entering electrical wiring into the house using SIP.

Before starting installation at the local Energy Supply Company, it is recommended to obtain a description of the technical conditions and agree on the procedure for entering electrical wiring into the house so that in the future there will be no disagreements with representatives of this organization.

For a single-phase input, the number of SIP cores per input should be two, for a three-way input - four.

If you use regular piercing clamps for SIP, then the cores will not need to be stripped. The required number of clamps is determined depending on the number of wire strands. The SIP is attached to the outer wall of the bath with an anchor clamp.

It is better to conduct SIP along the wall of the house in a plastic box or in a corrugated pipe.

SIP is brought to the place of entry into the house. In a separate sealed box, before inserting into the wall, install a two- or four-pole circuit breaker, depending on the number of phases. SIP goes to the machine, and from the machine, that is, inside the room, another wire will go, designed for internal wiring.

Choose the rating of the machine an order of magnitude higher than the machine in the introductory switchboard.

It is introduced into the building using a metal sleeve. Since the SIP is an aluminum wire, it cannot be conducted indoors. For the transition, sealed connectors are used: "copper-aluminum".

The hole in the wall through which the input cable will pass must be reinforced with a steel pipe with grounding.

Entering electrical wiring into the house from the street

The wire can be introduced into the bathhouse building (if it is separate) from the street using a steel pipe-rack, which is fixed on the roof or on the wall. The diameter of such a pipe must be at least 20 mm.

The upper end of the pipe must be bent in a semicircle to protect it from moisture.

The lower end of the pipe, which is embedded in the wall of the building, is attached with an angle of inclination towards the street by about 5-10 degrees.

The pipe is painted with bituminous varnish inside and out, and a hole is drilled in its lower part in order for condensing moisture to escape.

The pipe is attached to the wall with clamps, and its upper end is fixed with steel wire braces, which are attached to the roof with through bolts.

Insulators in the form of caps are attached to the pins of the pipe-rack.

The overhead line wire is led to the insulators and fastened with wire. If the overhead branch line is made with aluminum wire, then it is fastened with aluminum wire, if the wire is steel, then the fastening wire must be galvanized steel.

To the ends of the branch wires, the input wires are connected with clamps, which are passed through the pipe-rack.

Post insulators are used in installation when laying uninsulated stranded aluminum wire.

Underground installation method

It is necessary to lay the VBbShv cable with 4 copper conductors with a cross section of 10 sq. mm.

A trench is digging with a depth of 0.7-1 meters.

Sand is first poured into the dug trench with a layer of 10 cm, then the cable is laid, then sand again. In order to exclude possible mechanical tension of the wire inside the ground, the cable must be laid with a margin, namely in waves.

The cable is inserted into the construction of the bath through a steel sleeve.

Before entering the shield, the cable is stripped, connected to the machine, grounding and lightning protection are made.

It is not recommended to use metal pipelines for cable laying, as they collect condensate.

What power is needed, what devices must be taken into account

Before talking about power and current, let's give some introductory definitions and explanations of what a single-phase, three-phase connection, zero and ground are.

Single phase connection

Any electrical circuit consists of two wires:

the wire through which the current flows is called phase or
the wire through which the current returns is called zero or

On one wire, the current goes to the consumer of electricity (for example, to a light bulb), and on the other it returns back. This is how a single-phase network works.

Single-phase circuit diagram

Three-phase connection

A three-phase circuit includes three phase wires and one zero.

With a three-phase network, alternating electric current flows through three wires and returns one at a time.

Three-phase circuit diagram:

Energy sales organizations supply alternating electric current precisely through three-phase networks - this is how current enters our homes. Sometimes a three-phase network can be brought directly into the house. In most houses, a single-phase network is supplied. Finding out which network is connected to your home is very simple:

when there are 2 or 3 wires in the incoming cable, then the network is single-phase

when there are 2 or 5 wires in the incoming cable - three-phase.

grounding

In a single-phase network, this is the third wire that does not carry any load, but performs a safety function. The purpose of this wire is that in the event of a short circuit, the excess current through this wire will go into the ground.

Grounding scheme:

It is just necessary to calculate the power of electrical appliances in order to evenly distribute their load across the phases. It should also be borne in mind that modern electrical appliances are of sufficiently large power, which can create too high a load for a single-phase network. Therefore, depending on how much and what power of electrical appliances you are going to connect in your area, you can choose to connect a single-phase or three-phase network.

Advantages of a three-phase network:

Ability to use more power. A single-phase network is designed for a total power of approximately 10 kW, and a three-phase network is designed for up to 30 kW and more. Example: if 1 phase enters your house from a power line, then with an incoming wire cross section of 16 sq. Mm. the total power of all devices can be no more than 14 kW, and if there are 3 phases, then 42 kW.

It is easy to connect electrical appliances with three-phase power, such as electric stoves.

Disadvantages of a three-phase network:

You will need a stabilizer, since with an uneven load on one of the phases, the remaining phases will not work correctly.

It is necessary to integrate special equipment into the shield, designed specifically for a three-phase network.

We calculate the power

All electrical appliances (light bulbs, electric furnaces, etc.) have numbers:

first digit - voltage (options: 12, 24, 220, 380 V)

the second digit is the power of the appliance (written kW or k

To calculate the required wire cross-section, use the suggested example from the table:

Example for single-phase 220 V connection:

two-wire wire - phase conductor and neutral, or

three-core wire - phase conductor, neutral, protective conductor

In our example, according to the calculation, a wire with a cross section is sufficient 1.5 sq. mm.

If you do not want to go into formulas and reference books, then you can calculate the required wire cross section in a more simplified way:

Taking into account the power reserve, for every 2 kW of power corresponds to 1 sq. mm of the wire section. However, as the cross section increases, this ratio is not exact.

In our example, for 3.1 kW, wiring with a cross section will correspond. However, when choosing a wire, you should always make calculations with a margin of about 20-25%. In our example:

Spare power: 3120 x 1.25 = 3900 W
Current strength: 3900 W / 220 = 17.73 A
Wire section: 2.5 sq. mm.

Residual current device

Automata protection

Important!

One wire will go from the main shield to the bath one. It will carry the entire load, calculated on the basis of all electrical appliances. Branching wires will go from the bath shield.

A separate cable will go to the electric furnace.

A separate cable will go to sockets and a separate one to lighting.

The power and, accordingly, the cross section of the wire is considered separately for each individual wire, which will carry the intended load for it.

For example, an electric furnace has a declared power of 4000 W, then 4000 W x 1.25 \u003d 5000 W (calculated power for the furnace), 5000 / 220 \u003d 22.73 A (current)

Therefore, the wire cross-section for the furnace is at least 2.5 sq. mm. But, as practice shows, electricians will recommend that you take a wire with a cross section of 4 sq. Mm.

Example for three-phase connection (380V):

four-core wire - 3 phases, neutral

five-core wire - 3 phases, neutral, protective conductor

In this case, the current obtained from the calculation of the single-phase variant should be divided by 3. And already from the calculation obtained, select the wiring section.

In our example, the current strength is 22.73A / 3 \u003d 7.58 A. The wire cross section can be chosen less, while the number of cores will be 4 or 5.

We need the calculation of the current strength for the correct choice of the input machine. The machine is recommended to choose an order of magnitude higher than the calculated value of the current. In our example, the circuit breaker should be at least 25 A, and even better 32 A (according to the calculation, the current strength is 22.73A). The circuit breaker should be selected according to the weakest link in the circuit. For example, in the circuit there is a wire for an electric furnace, for sockets and for lighting. Accordingly, it is necessary to calculate the current consumption for each of these links and select a circuit breaker based on the very minimum current consumer. Outgoing automata in groups are selected according to the same principle.

Choosing an RCD

The RCD must be at a higher rating than the circuit breakers. The rated current is indicated by the manufacturer directly on the RCD equipment. This is the value of current that the RCD is capable of carrying for an extended period of time and above which the RCD will trip. There are RCDs with a rated current - 6, 10, 16, 25.30, 32, 40, 63, 80, 100.125 A.

That is, if in our example we choose a circuit breaker for 25 A, then it will be sufficient to set the RCD to 30mA. However, given the high humidity in the bath, it is recommended to set the RCD to 10 mA. With such a low RCD threshold, you are not afraid of an electric shock during an accidental breakdown on the case, such as a lamp, while the likelihood of false trips increases.

The most reliable option is to use the PUE guide to select the cross sections of wires, automata and RCDs, a guide.

Step by step wiring installation

cable entry into the bath (see air or underground method)
bath shield installation
wiring from the shield (see open or closed wiring method)
connection of luminaires (see requirements for the selection of luminaires)
connection of sockets (see requirements for the selection of sockets)
connection of the electric furnace (see the requirements for the selection of wires and placement of the electric furnace)

Installing the shield

The switchboard in the bath has the function of transmitting electricity to consumers:

sockets
switches
electrical appliances

Mounted in the shield: input machine, groups of outgoing machines and RCD

Requirements for the location of the shield

Free access to the shield

Ventilation without clutter

It is not allowed to place the shield in a place with a high temperature, for example, in a steam room. it is best to place it in the dressing room or rest room.

It is desirable that the shield be illuminated by a natural light source.

The ideal placement height is 1.4 - 1.8 m above the floor surface.

Connection conditions

The phase conductor (gray according to GOST) is attached to the upper terminal of the introductory machine.

From the lower terminal of the input machine, using jumpers, the phase core is connected to the upper terminals of all available outgoing machines. There is another way: the phase conductor is bred to outgoing machines using distribution bars.

The zero core (blue) goes to the zero block.

The protective conductor (yellow-green) is attached to the protective block or to a welded bolt in the shield itself.

The phase conductors of the wires going to the load are connected to the lower contacts of the machines.

The input and output wires are laid in the shield, and they are removed from the shield using corrugated or plastic pipes made of non-combustible material.

It is advisable to sign all the machines in order to know which consumer group this or that machine corresponds to.

The shield often stores the wiring diagram of the bath.

The cores must be well fixed in the terminal blocks. Insufficient fixation leads to heating of the clamps and burning of the contacts, and then the terminals.

Choosing electrical equipment for the bath

An electric furnace is designed to convert electrical energy into heat. Modern electric stoves quickly heat the stones and create the necessary heat in the bath. The heating rate of the steam room depends on the power of the stove. The stove is selected depending on the volume of the room.

Advantages of an electric stove over stoves:

Do not take up much space

Environmentally friendly

Do not take much time for the process of heating the room

You can adjust the desired temperature

Able to maintain the temperature for several hours.

No need to worry about wood

When choosing a stove for a bath, pay attention to the main characteristics that are indicated in the product passport:

Power/voltage

How much room heating is the stove designed for?

Dimensions

To make the right choice, you should know that modern electric furnaces are:

wall
floor standing
Thermos ovens
Stoves with a steam generator (make it possible to combine Russian and Finnish versions of a steam room in one room)

Electric furnace control can be:

manual (from the control panel)

remote (from PC, telephone, control room)

Maintenance and preventive inspection of electrical appliances and wiring

All electrical appliances, wires are designed for a certain period of operation. The service life of a device is usually indicated in the product passport. At the same time, all electrical appliances and wiring should be inspected:

rooms with a normal environment - at least once every 2 years

rooms with high humidity and temperature - once a year.

The RCD must be tested once a month by pressing the "test" button.

Once a year, check the tightness of the contacts connected by screw terminals (in the switchboard, in sockets where powerful electrical appliances are connected, in junction boxes.

What to pay attention to

In switches, springy contact plates can break off.

The springs weaken in the sockets, as a result, the contacts are melted.

In the shields, the contacts heat up or burn.

Circuit breakers fail - do not work.

The screw terminals that connect the wires loosen over time.

What is included in the service:

Failed switches and sockets cannot be repaired, they must be replaced.

The contacts on the shield must be periodically cleaned of soot and tightened tightly, if necessary.

The contact surfaces of fuses and circuit breakers must be free of dust and oxide.

Circuit breakers with a damaged housing or once failed to work are not subject to repair, but must be replaced.

Electric meters should not have damage to the terminals, housing.

The overhead wiring line is checked for chips, cracks, burns on the insulators, as well as the condition of the connections.

All electrical appliances are tested.

Let's name the approximate prices for typical services for the installation of electrical wiring:

Shtroblenie walls under the cable - 400 rubles / r.m.

Cable laying in a corrugated pipe - 95 rubles / m.

Installation of cable channels - 105 rubles / r.m.

Laying wires in cable channels - 45 rubles / r.m.

Installation of a switchboard - 4000 rubles / piece

In matters of grounding, each specific case must be approached individually. The organization of grounding in a particular area must be coordinated with local power networks. This is due to the fact that earlier the power grids were not calculated for the arrangement of grounding in each private house. We give only general information:

To make grounding in a free-standing bath, you need to create a separate circuit (center) of protective grounding.

Lightning protection includes:

down conductor in combination with a ground loop;
lightning rod

Lightning protection can be rod or cable.

Rod lightning protection is a metal pin installed on the roof of the house and connected to the ground loop using a down conductor.

Cable lightning protection consists of several pins with a cable stretched between the pins.

Common Questions

How to calculate the illumination of a room?

For an approximate calculation of the required power of fixtures, you can use the formula P = p*S/N, where S is the area of the room in sq.m., N is the number of fixtures, p is the average specific power for lighting, it is set depending on the purpose of the room. In baths, this figure is as follows:

for incandescent lamps - 10-30 W / sq.m.
for halogen lamps - 23-27 W / sq.m.
for fluorescent lamps - 6-8 W / sq.m.

Example:

For an incandescent lamp, we will take the average specific power indicator - 20 W / sq.m, then, with an area of \u200b\u200b15 sq.m. and the number of fixtures - 3: 20*15/3 = 100 W

Therefore, if you decide to install 3 lamps in a room of 15 sq.m, then each of them should have a power of 100 W - this will be the optimal illumination.

How to connect RCD correctly

We install a two-pole (VA) circuit breaker (1)

Contacts of phase and zero we start we start in the counter (2)

Other contacts are brought to the load, the diagram shows the direction to the RCD.

We connect the fire protection RCD (3).

The phase conductor is bred to (VA) circuit breakers (5,6,12)

The conductor is then routed to the differential circuit breaker (13)

The following contact connections are sent to the RCD (7)

They feed 3 machines (8,9,10), which are responsible for the operation of sockets (2,3,4)

Conductors (15,16,17) for sockets (5,6,7) are output similarly

After the fire RCD (3) we fix the neutral conductor to the zero bus (4)

From the zero bus (4) we start the conductor to the RCD (7 and 14) and to the differential machine (13)

Attention! The neutral conductor after the differential machine goes directly to the load, and not to the zero bus.

From the RCD (7) the neutral conductor goes to the bus (11). Zero conductors of sockets (2,3,4) will also be connected to it

Similarly, the RCD (14) is connected to the neutral conductors of the sockets (5,6,7)

Attention! Zero lighting conductors do not need to be wound through the RCD and busbar terminals (11.18). They must be brought under the contacts of the terminals of the common zero bus (4).

Zero bus is located in the housing (20)

All grounding conductors for the contact bar (19)

They did not use not only lamps, but even torches and candles, because the environment in the steam room was too humid and hot. Modern achievements allow wiring in all bath rooms for every “taste and color”, as they say. But, given the temperature conditions of the steam room, the highest safety requirements are imposed on the wiring and they cannot be neglected. We will talk about how to properly make the lighting in the bath in the steam room with your own hands.

In most cases, a bathhouse is built near a residential building. For bath wiring, a separate machine is required on the switchboard. Electrical wiring is carried out in two ways:

Underground. For laying the cable, a special box is prepared underground, laid through special holes in the foundation at a height of about half a meter. The entrance pipes to the bath should be 2 times larger than the cross section of the electric cable.

Ground. The wiring stretches through the air at a height of at least 2.5 meters and enters the room through a wall hole or roof. The cable is used bare or self-supporting. The second type is more reliable and practical.

Advice. Each wire must have a separate entry pipe. We place it at a slight slope to protect it from oblique rain jets.

Basic rules for the "correct" wiring in the steam room

In order for the bath electrical wiring to function clearly and reliably, all its elements must be selected correctly, and installation work must be carried out in compliance with certain rules:

Do-it-yourself installation of a lighting system in a steam room

Before you start wiring, carefully consider the location of sockets and switches (the ideal place is a dressing room / rest room). In addition, the cable should never run near heating appliances.

Lighting in the steam room is carried out as follows:

We have pieces of wires in a special metal pipe that will be used for electrical wiring in the steam room. There must be at least two cables to connect two light elements. One of them will serve as a "safety net" in case the second one burns out.
In the pair, the wiring is mounted exclusively of a closed type. In this regard, it is advisable to lay an electrical cable at the stage of construction work in a bathhouse or overhaul. We put the cable to the connection points of the lamps.
We mount and carefully insulate ceramic cartridges on the wire ends.
We mount lighting elements and hide them under heat-resistant housings made of porcelain or tempered glass (frosted). Wall lights must withstand temperatures up to 150 degrees, and ceiling lights up to 200.
We close the lamps with special protective grilles that will prevent burns if they are accidentally touched.

Advice. Try not to mount fixtures on the ceiling due to elevated temperatures. The best place would be the part of the wall located under the ceiling. In addition, in this way you will be able to create a subdued relaxing light.

Practical tips for choosing lighting fixtures for the steam room

The steam room in the bath helps us not only to warm up and steam the body, but also to relax and unwind. Therefore, the lighting for the steam room should be appropriate: muffled, weak, tuning in to a wave of relaxation.

Given the temperature characteristics of this room, the lamps must be extremely heat-resistant and absolutely hermetic, made of special materials. The best place to place the fixtures will be the corners and parts of the walls under the ceiling.

Among the variety of fixtures, fiber optics will be the best options for a steam room. They not only provide the right lighting, but also have a higher level of safety compared to conventional incandescent lamps.

Never use fluorescent lamps in a steam room, as when heated, they can explode and spread mercury vapor around the room. Too powerful incandescent lamps will also not work - they will heat the protective grilles for lamps. A power of 75 watts will be enough.

As for the shades, the most popular among builders are anti-fog matte or pastel colors. Additional lighting in the area of \u200b\u200bshelves and at floor level will look very stylish, moreover, it will only enhance the relaxing atmosphere of the room.

We told you about how to do the wiring in the steam room correctly. As you can see, everything is not so difficult, the main thing is to follow the safety rules and choose high-quality light elements from suitable materials. Good luck!
