How to connect wires to a double socket. How to connect a double socket: installing a double socket in one socket

The socket with a double connector will provide the ability to simultaneously power two devices connected to separate electrical outlets. In addition, for each of them you do not need to pull the cable, and it is more convenient to use due to the grouped arrangement.

The information offered for review is supplemented with step-by-step photo guides, visual illustrations and videos explaining the nuances of installing and connecting power devices.

The main elements of the electrical outlet are the outer protective case and the working part, including the base and contacts.

They are interconnected by screw terminals - clamps necessary for connecting the electrical equipment cable.

The only drawback of double sockets is that it is problematic to connect two high-power consumers of electricity through them at the same time.

There is an erroneous opinion that double sockets are identical to assembled or double models and are several independent devices located close to each other, interconnected by loops.

A double socket can be a real lifesaver in a room where several household appliances work. In such a device there are two connectors where you can turn on a couple of pieces of equipment at once. You can connect and mount the outlet yourself, if you know all the features of the installation.

Types of double sockets

An electrical outlet is a device required to connect electrical appliances to the mains. The product consists of a body (cover), which isolates the working part from external influences, and the main part with a base and contacts.

Sockets can be not only single, but also double, and even multi-socket, depending on the number of plug connectors. It is a mistake to think that to double single sockets means to get a double one; in fact, only a monolithic device is considered a two-socket device.

The disadvantage of double products in dividing the power of the electric current into two parts, which should be taken into account when connecting two electrical appliances at the same time.

There are different types of double sockets according to modifications:

1. Closed. The openings of the device are covered with special curtains, which is convenient for apartments where small children live.
2. Open. Outwardly, they are familiar sockets without closing shutters.

Devices can be with or without grounding. If grounding contacts are provided, this will protect connected appliances from power failures. There are separate types of sockets for mounting outdoors and in rooms with high humidity - waterproof. The former are protected from dirt and dust, the latter from water penetration.

Double products are:

• overhead (external);
• hidden (internal);
• standard;
• polar;
• programmed, etc.

Features of mounting a socket with two sockets

Before you start connecting the device, you need to determine where the phase and zero are. The easiest way is to study the wire marking: phase - brown, black, white or red, zero - blue, white-blue, ground wire - yellow-green.

If there is no confidence in the marking, you can independently check the location of the phase and zero. You can do it like this:

1. Put on rubber gloves.
2. Bring a special screwdriver tester to each wire.
3. Evaluate the screwdriver signal - the lamp will light up in the phase.

Before installing a double socket, you need to de-energize the wiring - turn the switch on the machines or one (desired) machine to the “off” position. Further, in the place where the product will need to be placed, the voltage is re-checked using a special screwdriver.

There are some features of mounting a double outlet, unlike a single one. The double socket has one socket (glass) with two divorced terminals, 1 mounting section for wires.

The installation scheme is as follows: a ground cable should be connected to the central or upper terminal, while the phase will be on the right, zero (neutral) on the left.

It is necessary to choose a cable only from the same material and with the same cross section as the main wiring. If you plan to install 2 sockets, you will have to drill recesses in the wall for them with a drill, observing the required distance for the holes. Before installation, markings should be applied to the walls if the old outlet was not here.

Tools and materials

From the toolkit, the master will need a cross-shaped and flat screwdriver, pliers, a device for stripping the braid (for example, a clerical knife), a level. If you plan to install the device in a new location, you will need a hammer drill to drill drywall, concrete or wood.

To install the socket, additional materials are needed:

• insulating tape;
• socket box;
• self-tapping screws.

A cable of the appropriate material will be needed if you have to make a new outlet, and not change the old one. If possible, it is recommended to lay wires in the corrugation - this is an additional fire safety measure.

Installation sequence of a double socket

When the connection diagram for a double socket is correctly determined, the place is selected, and the materials are prepared, you can proceed with the installation.

When the product is a solid block, it can even be placed in the former place of a single device by slightly expanding the size of the niche in the wall. This will not cause the need for repairs, but will require careful wallpapering.

Dismantling the old outlet

Once again making sure that the machines in the apartment are turned off, you can proceed to remove the old outlet.

The procedure is as follows:

1. Unscrew all screws that secure the product.
2. Remove the outer cover of the old device.
3. Unfasten the wires, unscrew the fixing tabs.

The new product that needs to be built in should also be disassembled. The front panel must be carefully unscrewed from the working part.

New double socket box

Close attention should be paid to the quality of the new socket - it must be high enough, and in this case you can be sure of a clear fixation and normal operation of the socket.

The socket box is attached to the wall with side holders, which are sold separately or come in one package. Cheaper socket boxes are not fastened with special paws, but with screws.

The procedure for mounting the socket is simple. The screws on it must be tightened clockwise, the holders will disperse to the right and left, securing the product itself. But as you work, the glass always weakens, so the best option is to further secure it with alabaster.

Instructions for action:

1. Dilute dry alabaster powder (you can replace it with cement) to the consistency of sour cream. You need to take a small portion of the powder, since the composition instantly hardens.
2. Put the mass in the place of the future socket box, slightly wetting the niche with water.
3. After 20 minutes, a socket box can be attached to the hole in the wall.
4. Align the position of the glass with a hammer and a level so that it is perfectly level.
5. Next, close the gaps between the product and the wall with a new portion of alabaster.
6. Remove excess weight with a knife.
7. Fasten the glass with the screws without overtightening them as the plastic may crack.

Preparing to connect

The cable must be uncovered to ensure proper bipolar wiring. A sharp knife will help you quickly remove the outer insulation from the desired cable. Too long a supply of wires should not be left, otherwise it will create inconvenience when connecting the outlet.

It is considered optimal to expose wires from insulation by 1 cm. The total supply of wires usually does not exceed 12 cm. Shorter wires can be lengthened. Next, it is allowed to proceed to the most important stage - connecting a double socket with grounding.

How to connect wires

At this stage, it is necessary to clearly highlight the wires available in the working part of the product, identifying zero, phase and ground wire in them by color.

The procedure is as follows:

1. Loosen the bolts on the terminals intended for connecting the wires.
2. Insert the socket wires into the contacts.
3. Tighten the screws carefully with a screwdriver.

The main point is to connect the ground cable to the corresponding wire in the product (there is always a “ground” icon at its location). It is important not to connect the phase and neutral to the same contact - a short circuit will occur.

Product installation

Careful laying of wires in a glass is very important: if this is not done, sooner or later the cable insulation will be damaged, the operation of electrical appliances may be impaired. The wires must be rolled up without sharp bends. They should not be in the socket directly under the mounting bolts.

At the end of the work, the socket must be deepened inward and secured with mounting paws or screwed with self-tapping screws. Then you need to give it a level position using a level, and connect the caliper to the installation box block.

The last put a decorative overlay - a new socket with two sockets is ready!

Before you start repairing an electrical appliance, you should remember some simple safety rules.

First you need to find out what is the reason for the replacement. If the device simply does not hold well in the wall, then it is enough to tighten the screws. A pungent smell, smoke, or electric shock indicate that a new outlet is a must.

Rules that allow you to avoid injury when changing the outlet:

1. Turn off the power supply in the entire apartment. To do this is quite simple. The shield is usually located in the corridor or entrance. If the meter is old-style and has plugs, then pressing them will de-energize the entire apartment. Many houses now have electrical panels in the form of boxes. In this case, you need to find the levers on it and move them to the off position. Some craftsmen believe that they know all the wiring well and neglect this simple rule. Often the consequences in such cases are deplorable.
2. Do all day work. The only exception is the case when repairs are needed at a given time, and the normal life of the family depends on it. You can use a flashlight and rubber gloves. In other cases, it is better to postpone the dismantling for a bright period of the day.
3. Both the installation tools and the socket itself must be of excellent quality.
4. If the installation of electrical equipment is carried out for the first time, then you definitely need to study the step-by-step instructions for replacing and installing. A detailed guide is described in this article.

Instructions for dismantling the socket

1. Removing the protective cover of electrical equipment. To do this, take a crosshead or flat screwdriver. The screw, as a rule, is always one and it is located between two holes for supplying electricity. If the socket is double, then there are two screws, unscrew both. Carefully remove the panel.
2. The next step is to check for voltage. There are 2 types of wire: contact and zero. We alternately connect the phase to each of them. After full confidence in the absence of voltage, you can continue to work.
3. Dismantling the mechanism. No matter which socket is outside, there are 2 screws on the inside equipment on 2 sides. They hold paws that connect two components. Above and below there are a couple more bolts, they fix 2 wires. Loosen all 4 screws one by one. They can be thrown away, because. most likely they are already badly scrolled. For a new installation, it is better to buy new screws.
4. There should be 2 cables left in the hole in the wall. If they are bare, then it is necessary to wrap them with electrical tape.
5. The last dismantling step is to check the size of the new socket. If it does not fully enter the wall in depth, then you can cut it. This option is suitable for plastic specimens. If the equipment is made of metal, then you will have to deepen the hole in the wall.

It should be noted that during dismantling, you can find what is missing. Such sockets were often installed in old houses, in order to save money.

Of course, this is wrong and you should not repeat the mistakes of others. In this case, do not get lost, you just need to carefully detach the outer part.

Preparing a new outlet

A socket box is not always required during installation. It depends on the design of the new electrical equipment. In some modern designs, the central part itself is used as protection.

Let's consider this option in more detail.

The appearance of this option is different in that there is a special metal frame around it, and the mechanism is initially attached to the rim itself.

Such equipment is sold in one piece, i.e. outer panel, frame and mechanism are interconnected. To start installation, you need to detach the outer part from the protective frame. Fastening is carried out using bolts, so they just need to be unscrewed.

Only the bezel and mechanism remain.

Upon closer examination of the mechanism, you can see that there are no longer 4, but 5 screws on it. The latter is located at the top between the two contact. This bolt holds the special plate.

It presses the contact wires more tightly, which allows you to install the plug firmly. It also serves as additional protection against electric shock.

Installation instructions

Euro socket installation:

1. We remove the insulation. We measure the depth of the hole intended for the cable. If the size does not match, you need to clean the protective layer of rubber. The bare cable should protrude quite a bit from the hole;
2. Using the clamping screw, insert the first wire. The fixation must be very secure. If this is not the case, the outlet will stop working pretty quickly. To do this, the cable must be gently pulled, it should not move from side to side;
3. Repeat the same procedure with the second wire.. We must not forget about accuracy when exposing wires.
4. In case equipment with grounding was purchased, a special cable is required. It is not available in all homes. In new houses or apartments after repair, such a cable is usually present. The cable is inserted into the upper opening of the mechanism. If the house is old and there is no ground wire, then this step is not required. It should be noted that equipment without a ground wire will not be able to supply electricity to all types of plugs. Therefore, it is worth thinking about its implementation;
5. The main network connection is complete. Next, you should install the mechanism in the hole in the wall and fix it with the help of quick paws. A protective plastic panel is installed outside.

Installation requiring a new socket box:

1. A new box is required when it is not possible to fix the paws on the old socket. It was mentioned above that during dismantling, it is checked whether the new box fits into the old recess. Therefore, during the installation phase, the new structure must ideally fit into the wall. To hold the socket firmly, you need to fill it with a special solution, such as glue.
2. The fixation of the new mechanism depends on the design. These will be quick paws or screws that are screwed to the box itself.
3. We expose the wires. This is done as in the first option.
4. We connect the cables to the common mechanism. The protective frame is not removed, but also remains attached to the equipment.
5. We fasten the screws on the top and sides. We install the outer plastic panel and frame. Installation completed.

Features of installing a double socket

There are 2 mechanisms for connecting such equipment. The first implies 2 power outlets from one point. This is an extremely unsafe option.

This is due to the fact that the current strength remains unchanged, and the voltage and load increase. It follows from this that such an option is short-lived. In addition, the mechanism has significantly fewer fasteners than the single version, so contact with the plug will be weaker.

Double holes are best taken from different points. This means that the outer panel will be doubled and connected together, while the power sources inside will be different.

In this case, the risk of voltage surge and electric shock is the same as in single sockets, i.e. almost zero.

It should also be taken into account where exactly such a mechanism will be installed.

So, for example, when installing in a concrete wall, a small number of holes for fastening does not matter, because. the base is very strong.

Walls made of chipboard, OSB or fiberboard will not be able to hold such equipment in themselves for a long time, over time the mechanism will begin to fall out.

Necessary equipment

Socket

It is best to choose new samples. Namely European production. In them, the forks are held more firmly, and the design itself is very stable. Devices made in Russia are also of good quality.

It should be noted that if old Soviet-style sockets are installed in the apartment, then replacement must be carried out. Such equipment can fail at any time.

socket box

As a rule, they have a standard diameter of 7 cm. There are also larger options, but they are required for old-style sockets. Therefore, if drilling the wall is not included in the plans for repairing the outlet, it is necessary to measure the hole before buying the socket.

The material for using this electrical equipment varies. Is it plastic or metal. If the wall is concrete, brick or any other non-combustible material, then you can safely install metal sockets. Wood, plywood or drywall are very fragile. Therefore, to install an outlet in such rooms, you need to use a plastic base.

Screwdriver

Basic equipment for mounting and dismantling. All sockets are attached to bolts and screws, which is why it is impossible to imagine such a repair without a screwdriver.

Insulating tape

Used as wire insulation to eliminate the risk of electric shock. Required to extend old wires.

Voltage indicator

It is necessary in order to check whether there is voltage left in the circuit. Both contacts need to be checked. If the indicator has not changed, then you can safely get to work.

Gloves

Both woven and rubber samples are used. In the case when there is absolutely no voltage, the first option can be used. Rubber gloves are used if there is no voltage indicator available, because. rubber practically does not conduct electricity. They are inconvenient to work with.

1. If there is no earth cable in the house, do not refuse to buy a mechanism with such a hole. They cost a little more. But at the same time, the structure is installed in the wall more firmly, which prolongs the service life. The contact with the fork is also much stronger;
2. Bare wire contact should be carefully measured. If it comes out of the hole too much or, conversely, is not visible at all, then the socket will last a short time. In the near future, you will have to repeat the procedure.
3. If it is possible not to install a double panel from one point, then it is better to put two single mechanisms with different connections;
4. When all the wiring in the house changes, you should change the height of the sockets. It should be about 20 cm from the floor.

It is very difficult to find electrical wiring that is located in an apartment without sockets. It is impossible to connect electrical appliances without a high-quality outlet in the apartment.

In the modern world, the current load is greatly increased. It is important to correctly parallel the connection of outlets. This is one way to connect sockets.

Parallel connection of sockets is the safest. The type of socket is of great importance. Today, sockets with an engraver are increasingly common. He is able to automatically restore contact. Parallel connection of sockets can be done independently.

First of all, you need to remember that when connecting the necessary wires directly to the contacts, be sure to fold the end of the wire. This must be done in the form of a ring, in order to create a sufficient area for contact.

This will serve as a kind of guarantee for the correct connection of powerful electrical consumers. parallel connection of sockets is very often used in everyday life.

It happens that a single functional outlet is not enough in a room, and then a decision is made to install another one, which will help defuse the load on the first one. Parallel connection is ideal for this case. Do not pull new wires from the existing electrical unit. Everything can be done much easier.

Parallel connection of sockets should be carried out very carefully. In this case, there are some features. First of all, the ends of the new wire are connected exactly in parallel, hence the name. The connection takes place precisely to the wires that fit the first outlet.

This is a very important nuance. To make it easier for you to understand, we will explain the whole connection mechanism in more detail. You need to connect "phase" to "phase", and in turn, "zero" - to "zero". We recommend that you connect the phase wire to the outlet socket, which is located on the right.

When making a parallel connection of outlets, it is very important to observe safety precautions. Don't overlook the small details. Please note that in the process of connecting a parallel socket, it is important to pay attention to the material of the wires.

It is necessary that the material of all dips used be identical. This is a very important point. Do not connect wires made of copper with aluminum wires. In the event that the connection of wires from different materials cannot be avoided, it is recommended that they be tinned.

Parallel connection of two sockets

Parallel connection of two outlets is used if there are electrical outlets of the same group. Parallel connection of two sockets can be carried out in several ways. You can connect wires in parallel.

You need to connect the wires in junction boxes. You can also go the other way and connect the outlet using the shelf.

The second option is worth choosing if you want to connect sockets that are very close to each other. Before installing sockets, perform a few necessary operations. To begin, mount the boxes of the sub-socket type and lay the wire to the distribution type shield.

Parallel and serial connection of sockets

Sockets can be connected in parallel or in series. Parallel and serial connection of sockets should be carried out in different cases. Electricians do not recommend daisy chaining sockets.

But this is a moot point. To begin with, it is necessary to analyze what is the difference between these two methods. It is worth starting with the fact that all sockets that are in the same group have an identical connection scheme. It's called parallel.

The issue is that parallel connection can be done in several different ways. You can connect sockets by wrapping them in boxes, including twisting, soldering and terminal, or you can connect them at the terminals, without operating the box.

The last method is called daisy chaining.

To make it easier for you to decide which socket connection to choose - parallel, or still serial, we offer a detailed comparison of these two methods. With regard to daisy chaining, this method can help save on material. Thus, you have to do less work and spend less resources.

But in this case there is a risk, because today it is not allowed to break the PE conductor. It is written in the generally accepted norms.

These rules can be circumvented only if you are replacing wiring in your own apartment or house. You do not need to hand over the given objects in operation, and, therefore, no one will check them. Which method to choose is up to you, but we do not recommend that you risk your safety and the safety of your loved ones once again.

You can make a daisy chain connection and still avoid violating security rules. To do this, you just need to leave the current-carrying type wires unbroken, namely the phase and neutral wires. This will allow you to reduce the load on the main terminals of the first outlet.

If you carry out the above procedure correctly, then this will keep the PE conductor intact, and thus you will not violate generally accepted safety rules.

And also you can watch the video connection of the socket and switch

The situation when the number of electrical appliances working at the same time exceeds the number of sockets in the room is no longer a rarity today.

We have to resort to the help of tees and extension multipliers, which is not only not convenient, but also not aesthetically pleasing.

A more rational solution is to replace one or more sockets with double ones: there will be more sockets, and you won’t have to ditch the walls to lay new wires. How to choose and how to connect a double socket - read about this below.

Double sockets are available in a variety of designs. Here's what they are:

1. With grounding and without grounding. In the first case, in addition to the main ones (phase and zero), the socket has contacts for connecting the ground wire (inside) and the ground contact on the device plug (outside). If a two-wire wire is connected to the electrical outlet or there is no ground contact on the plug of the device, then it makes no sense to purchase a double socket with grounding.
2. Open and closed. The latter are equipped with shutters that cover the holes in the outlet when no device is turned on. A child will not be able to insert a nail or pin into a closed outlet and receive an electric shock. The curtains move back only if there is a simultaneous impact on each of them, that is, when the plug of the electrical appliance is plugged into the socket.
3. Conventional and in moisture-dustproof design. The level of moisture and dust protection is indicated by an index consisting of the letters "IP" and two numbers. For installation in rooms with high humidity, IP44 class sockets (equipped with a cover) should be purchased, but if the electrical outlet is located on the street - IP55.
4. Programmable. This outlet has a timer with which you can set the time to turn off or turn on.
5. Spring loaded. Inside such an outlet there are springs, and on the body there is a button. When the button is pressed, the latch holding the fork is released, and it is pushed out by the springs.
6. Embedded and overhead. In the first case, the front surface of the outlet after installation will be flush with the wall, in the second - somewhat protruding.

Double ground socket

Sockets can have a different shape of holes - depending on what type of plug the product is intended for.

Installation tools

To quickly and efficiently install the outlet, you will have to arm yourself with something.

We will need:

• phase indicator (looks like a screwdriver with a light bulb at the end);
• crosshead screwdriver;
• wire cutters (can be replaced with pliers);
• well-sharpened knife.

If the outlet is installed in a new place, you will have to get a puncher.

Preparatory work

The amount of preparatory work will depend on whether the outlet is being installed in a new place, or they simply want to replace the old ordinary outlet with it. Let's consider both options.

Preparation before replacing the outlet

If there is already a socket at the installation site, it must be dismantled. This can be done only after disconnecting the outlet from the power supply. Turning off the machine, you need to use the phase indicator to check whether the electric point is really turned off.

Dismantling the outlet

Dismantling the socket is performed in the following sequence:

1. First, remove the front panel by unscrewing the screw holding it. Sometimes, to access the fasteners, you need to pry off a plastic decorative panel that is held on by a latch with a flat screwdriver or a knife.
2. Having gained access to the inside, unscrew the screws holding the wire strands in the terminals.

Preparation before installing a new outlet

As part of the preparatory work, a wire must be laid from the junction box to the installation site of the new electrical point. To do this, a channel is punched through the wall with a perforator - a strobe.

When the strobe is ready, a wire is laid in it. It is best to place it in a corrugated tube. In this case, the wire, if it burns out, can be easily removed and replaced with a new one without breaking the plaster.

Gate socket

After laying the corrugated tube with the wire, the strobe must be covered with a cement-sand mortar.

Connecting the wire to the terminals of the junction box is performed after installing the outlet.

Now you need to make a recess in the wall in which the new double socket will fit.

Marking on the wall

In that place on the wall, you need to make a mark with a pencil. To install a double socket, in the design of which there are two glasses, it is required to measure the distance between the drilled holes. For this purpose, the location of the central point of one of the sockets, which is located at the intersection of the diagonals, is determined. In a similar way, the central point of the installation box No. 2 is revealed.

Layout of outlets in the kitchen

In order for the notch to have the correct round shape, you can first make an annular cutout using a crown mounted on a drill, after which the material inside the cutout is knocked out with a chisel. The diameter of the crown should be 2 - 3 mm larger than the diameter of the socket. In the absence of a crown, a recess is formed with a drill, drilling several holes and then selecting the remaining material with a chisel.

You need to go deep enough so that the mounting box fits completely in the recess without protruding from it.

Mounting socket boxes

Before attaching the mounting box, you need to lead the wire into it. Next, the part is placed in the recess and fixed. Most models have holders (legs), which, when the corresponding screws are tightened, diverge to the sides, resting against the walls of the niche.

As practice has shown, such latches do not provide sufficient strength: the force acting on the socket when the plug is pulled out increases due to the lever and over time loosens the mount.

Installation of socket boxes in a concrete / brick / aerated concrete wall

For greater reliability, you have to put the installation box on the solution. Any one will do - cement-sand, alabaster or gypsum. In order for the adhesion force between the solution and the niche to be maximum, the walls of the latter must first be moistened with water. The socket box is not installed immediately after laying the solution, but after 20 - 30 minutes, when it grabs a little.

Having filled the gaps left between the box and the wall with a solution, they remove its excess and this completes the installation of this part of the outlet.

Holders are not always included. When buying, you need to immediately check whether the socket is equipped with them, and if they are not found, these parts should be purchased separately.

Mounting boxes of inexpensive sockets are often fastened with dowels. In this case, additional fastening with a solution is not required.

Socket wiring and wiring

At this stage, it is necessary to connect the wire strands to the contacts on the inside of the outlet. You need to act in the following sequence:

1. The end of the wire is released for a length of about 10 cm from the outer insulation, after which the cores will be separated. With such a length, it will be convenient to work, and the wire will easily fit into the box.
2. It happens that the end of the wire protruding from the wall is too short and has to be increased. In this case, it is desirable to connect the cores by soldering or using special connecting terminals. The twist can have a lot of resistance and get warm because of this. If, nevertheless, the wires have to be connected in this way, then they need to be twisted as tight as possible, using pliers for this.
3. The ends of the cores are cleaned to a length of 1 - 1.5 cm from the insulation. Stripping can be done with a knife, but this must be done carefully so as not to damage the conductor itself. You can also use one of the special tools - a stripper or a puller.
4. Now you need to determine which of the cores is the phase, which is the neutral, and which is the ground. If you did not install the wiring, you cannot rely on color coding - it could be confused. The phase is easy to determine: you need to turn on the machine, supplying power to the electrical outlet, and touch the wires in turn with the phase indicator.

Wiring in a one-room apartment

Before applying power, make sure that the bare ends of the wires do not come into contact with each other. Contact will cause a short circuit.

There are two ways to distinguish a ground wire from a neutral wire:

1. Measure the voltage between the phase and each of the other two conductors with a voltmeter. When the second probe comes into contact with the ground conductor, the readings on the device will be slightly higher than when in contact with the neutral.
2. Measure between each of the tested conductors (that is, not phase) and some grounded metal object, for example, a heating pipe. Upon contact with the "ground", the device will show "zero", upon contact with the neutral - some meager value.

It is customary to connect the neutral with blue insulation, and the ground with yellow-green insulation. The phase is usually connected to a residential one with brown insulation.

In conclusion, it remains to clamp the ends of the wires in the screw clamps of the inside of the socket, install it in the socket and screw the front panel.

Connecting a double socket

A double socket should not be confused with two separate ones. It is connected by one wire, so the total power of the included devices should not exceed the power for which this wire is designed.

In addition, the outlet itself has a limited bandwidth: the current flowing through it should not exceed 16 A, that is, devices with a total power of up to 220x16 = 3.52 kW can be connected to such an outlet.
