Electric stove connection. Repair, connection of electric stoves - their electrical circuits. Electric stove Electra

TO necessary tools to connect include the following:

a puncher and a grinder for the formation of strobes, seats for sockets, with a surface cable, which is highly not recommended, such tools will not be needed;
cable pliers;
screwdriver;
indicator;
drill;
measuring devices for marking the position of all elements of the chain;
insulating material;

The only problem is education seat in the wall under the socket and cable. The rest of the work is simple and can be done without any problems.

Schemes for connecting electric stoves

single phase

The most common scheme, since in residential premises there is no three-phase power supply in 90% of cases. In this case, one phase is connected to the terminals L1, L2, L Copper jumpers are installed between these terminals, which often come with the stove. A jumper is also installed between terminals N1 and N2 and the “zero” cable is connected to them. There is a special "earth" for the core.

Two-phase system

Used quite rarely. Often, in the country, you can find a situation where there are only two phases with a three-phase power supply. In this case, a two-phase connection system is used: a jumper is installed between terminals L1 and L2 and phase A is connected, and phase B is thrown to terminal L3. "Earth" and "zero" are connected in a similar way.

Three-phase system

Somewhat different from the above. The main difference is that you don't need to use any jumpers. Phase A is connected to terminal L1, phase B to terminal L2, and C to terminal L "Ground" and "zero" are also connected according to the previous diagrams.

Similar features apply to wiring diagrams electric stove.

Step-by-step instruction

First, let's highlight some of the nuances:

You should create a plan for the future food chain.
According to the plan we mark the future location of the electrical cable, socket and.
We carry out the creation of strobes under the electrical cable. It is recommended to deepen a few centimeters, since concrete, brick have good dielectric properties, and also do not ignite. Such a recess will protect the cable from mechanical damage, and Decoration Materials from fire during insulation breakdown.
We carry out the creation of a landing hole for the outlet. It is worth remembering that the more accurately it was done, the better the socket mount. Otherwise, it may wobble.
After the previous work has been done, we lay the cable, connect it to the outlet. At the same time, we note that the connection of several pieces of cable is not allowed.
We carry out the connection of the power plug to the plate according to the above diagrams.
If the machine is connected to the network, you need to install it in the electrical panel.
We connect the cable to the machine or other power source.

When carrying out work, it should be remembered that the network must be de-energized. To do this, the circuit is first disconnected from the energy source, and then the presence of current on all branches is checked using an indicator or a multimeter. It is worth remembering that when cutting the cable, you should leave the ends with a margin.

Connecting the power plug or cable directly (not recommended) can be done as follows:

We open back cover plates and get access to the terminals through which power will be supplied.
A massive block is hidden under the back cover. We carry out unscrewing the bolts by half.
We clean the ends of the wire strands so that there are enough of them to trace around the bolt. At the same time, it is worth noting that their large length is the main mistake. Under some circumstances, there is a possibility that the strands will touch and a short circuit will occur.
We bend the ends of the veins and throw them on top of the bolts. We breed the veins to the maximum distance.
We twist the bolts without applying excessive force. Excessive force can lead to a violation of the structure of the villi. However, the cores must have a strong connection.
We close the lid.

Possible difficulties:

The formation of the correct niche for the outlet. For perforators, special nozzles were created that allow you to create a niche of the required shape and size.
You can often meet the situation when the kit does not include the jumpers necessary to complete the work of connecting the stove. You can create a jumper yourself, for which you can use a small piece of the wire used. This feature means that the jumper will have a cross-section selected taking into account the minimum allowable value.
You can meet a situation where the cut cable is not enough. In this case, it is worth remembering that the presence of connections between pieces of cable in this case is not allowed. This feature is due to the fact that it is at the joints that the greatest resistance and heating is created. The insulation used may not be able to withstand the load.

Some problems cannot be fixed on their own. Previously, a common occurrence was the situation when a common machine for an apartment or house could not withstand the load. Its replacement can only be carried out by employees of the power grid.

Grounding guide

When working in old-style networks, even experts often make gross mistakes. An example is the case when grounding is performed on the operating zero bus. In a situation where the current is cut off by the wire, it is supplied to the appliance and the user will be shocked. Also, you can often find a situation where the "zero" lived and the phase is confused.

The result of such connection will also result in electric shock to the user. However, it is impossible to refuse to connect "zero".

First, you should find out if the shield has a ground. To do this, you can use the help of an electrician or visit the Housing Office, another service organization with a similar question.

The answer to the question must be given clearly, supporting documentation must be provided. Otherwise, you should not believe the words.

Residents on the ground floor or own house can solve the problem like this:

Outside three pipes with a length of 250 centimeters and a diameter of at least 16 millimeters are dug in.
They are connected between themselves.
ferrule wire from the shield is led to the dug-in pipes.
We make connections e zero bus.

In a similar way, you can create an outlet circuit for electricity.

If it is not possible to create a diversion circuit, follow the instructions below:

Plugging the wire, which is responsible for "zero".
When installing the plate we pay attention to the fact that it is not in contact with other electrically conductive elements, for example, with pipes.
Near the stove you should put a dry mat that has dielectric properties.
regular machine change to a differential model with a limit of 30 A.
Showing Caution when using the plate.

Requirements for wiring and other circuit elements

selection of cable section

There are several basic requirements that must be met to ensure reliable operation of the electric stove. These requirements are due to the fact that the considered consumer of electricity has a large capacity and this creates a certain voltage in the network.

Increasing the voltage leads to heating of the wiring and other elements if they were not designed for such a load.

The main requirements for electrical wiring include the following:

One of the points of the PUE defines that only copper wires can be used in residential premises. It is possible to use aluminum wires in residential premises only if their cross section is 16 square meters. mm and above this indicator. It is not worth using wiring of this section at home. This feature is associated with many features of the considered alloys, from which the wiring is made.
If at home or in an apartment single-phase power, a three-core cable should be selected. In such a cable, one wire indicates the phase, the second zero, the third ground. If the house uses old wiring, it is worth replacing it. With a three-phase power supply, it is worth choosing a five-core cable. In this case, three wires will indicate the phases, the other two - zero and ground.
When choosing a cable Special attention given the magnitude of the cross section. According to accepted standards. when the stove is powered from a 220 V network, it must be at least 6 sq. mm. However, this value is an average, it can be more or less. An example is the connection of a stove that has a power of 7 kW. In this case, a cable with a smaller cross section can be used. For a three-phase network, use a cable that has a cross section of 2.5 sq. mm. It is worth noting that it is possible to use various tables that provide recommendations for the thickness of the cable cores, depending on the power of the consumer. Also, there are special calculators that carry out the calculation. Therefore, in this important calculation, the help of a specialist is no longer needed.
The last selection criterion you can name who is the manufacturer of the cable. In this case, it is recommended to choose a manufacturer based on the conditions under which the cable will be laid. Some manufacturers create designs that are designed to power electric stoves.

When considering this issue, we immediately note that, according to accepted standards, sockets and other power sources cannot be included in the stove connection network. Therefore, the cable is selected only for the features of the plate.

It is recommended to enter into the circuit to protect the cable circuit breaker, which will work exclusively with the stove. The current rating of the circuit breaker must be 32 A.

It is worth noting that established rules do not require the inclusion of this element in the power supply circuit of the stove, but it will not be superfluous. After all, only an automatic machine is able to quickly de-energize the circuit in the event of a dangerous situation.

The choice of sockets and plugs should also be taken with great responsibility. Their minimum values of the operating current must correspond to the indicator of the installed machine. If the machine is designed for 32 A, then the socket and plug must also have similar indicators.

A three-phase plug with a socket must have additional housing protection that will prevent accidental pulling out of the plug. During disconnection, the three-phase socket must be protected from accidental entry of foreign elements.

While doing work you need to be sure that no one will turn on the power supply again.
Also, do not rush while working. because mistakes can have serious consequences.
Previously, it was popular to conduct grounding through heating and sewer pipes. Despite the fact that according to the rules they must be well grounded, in practice no one controls this. In the event of a plate failure, not only your apartment, but also your neighbors may suffer.
Conduct grounding through other communications is also prohibited.

Content:

In an apartment and a private house, the owners can either choose between a gas and electric stove for their kitchen, or install an electric stove or stove without fail. For example, as provided for many high-rise buildings, or in the absence of gas pipe, or unwillingness to connect and use gas cylinders at the cottage or in a private house. It is necessary to properly connect the stove to the mains. This is one of the most powerful 220 volt electrical appliances that works for a long time. And the consequences of mistakes made when installing electric stoves can cause large losses.

An electric stove that is not properly connected can cause a fire.

But connecting the stove to the network is within the power of most households. You can independently connect an electric stove not only to a single-phase network. Connecting the stove and electric stove to a three-phase electrical network, as well as a two-phase connection, is also incorporated into the design of these electrical appliances. Next, we will talk about this and, after reading the article, it will become clear how to properly connect the electric stove with your own hands. It will also be useful to read the article before connecting the stove or connecting ovens.

Existing Solutions

The main feature of electric stoves is their large power by household standards. In some cases, only sauna stoves and some electric heaters can be more powerful. heating devices. A current of 35–55 amperes is a fairly common parameter for electric stoves. For this reason, in electrical circuit minimum connections required. Each of them can become, if the contact deteriorates, a source of dangerous heat, which can result in an accident.

Fewer connections - more reliability and durability. Therefore, the most correct connection there will be a separate wiring for the electric stove, connecting it and the switch with RCD functions. But if there is a need to use a plug-in connection, a socket can be installed to connect an electric stove. But at the same time, it is important that the design of the contacts of the device correspond to the current consumed. Since there may be situations in the kitchen that are fraught with electric shock, the electric stove must be connected to ground.

The connection scheme of the electric stove is selected depending on the number of phases that are used. Usually there is a special nameplate on the case, which shows the connection diagram of the electric stove to one phase, two phases and a three-phase network. Or these schemes are given in the technical data sheet. This data gives an idea of how to properly connect the electric stove yourself. The following shows generalized options for how to connect the device according to the number of phases of the mains.

About switches

The load capacity of the contacts of a differential machine or circuit breaker, which must be used together with an RCD, must not be less than the value of the maximum current consumed. Since this parameter for switches is standardized and broken down into certain values, and the power of electric stoves is different, most often they choose the desired value from three denominations - 40, 50 and 63 amperes. The electric cooker current must be less than the selected commutator current.

But if the homeowner is sure that his electric stove will never work on full power, he can independently determine the current of the switch (circuit breaker or differential machine).

If a circuit breaker and an RCD are used, the last one in terms of current rating should be the next in ascending order. If the circuit breaker is designed for 40 A, the RCD must be selected for 50 A.

Choosing conductors

Connecting the electric stove to the mains is best done with a conductor with copper conductors. The copper cable for the stove will turn out to be thinner than aluminum. Its connections to the terminals will be more reliable. Regardless of the material of the cores, the wire cross section, as well as the cable cross section, is selected according to special tables. Their content is the same, although the formatting of the data may differ. One such table is shown below.

If the tile will be connected directly to the switches and will not be rearranged, you can use electric stove wires, the cores of which are made of one wire. To connect to the mains with a plug connector, it is better to use a cable with stranded wires between the tile and the plug. The use of such a cable for an electric stove is better because of its flexibility.

Next, for example, consider connecting two models of electric stoves to the mains. One will be combined with two electric and two gas burners and therefore less powerful, and the other will be fully electric - more than twice as powerful as the combined one.

Connecting a less powerful electric stove

The delivery of this model does not include a cable for the electric stove. Therefore, when buying, it is recommended to ask the seller about the cord, if he himself does not comment on this option. If the selected electric stove is supplied without a cord, it is better to immediately buy a cable for connecting the electric stove, based on the data in the table above. We remind you which cable is needed to connect to a 220 V network. It must contain three cores, one of which, with a yellow-green color, is intended for grounding.

This model consumes approximately 4 kW electrical power. The cable for it is shown in the images below.

To keep the cable closer to the wall and out of the way, we recommend using an angled plug.

Before connecting the electric stove, the back cover is removed. Under the cover is a mounting block, which is used in all electric stoves.

The far right terminal is for grounding. This can be seen from the color of the insulation of the connected wires. The remaining terminals are numbered so that connections can be made depending on the type of power supply. To do this, a nameplate with images of the connections for each of the networks is glued to the back cover.

The image shows adjacent terminals that are interconnected. Jumpers are used for these connections and should be included in the scope of delivery. Usually they are all installed together in the terminal block. They must be removed and mounted in accordance with the selected connection in relation to the existing electrical network. For installation, the terminal screws are slightly unscrewed so that the jumper fits under the screw head. And after placing the jumper, the screw is tightened until it stops.

The cores of the connecting cord are connected to the terminals of the block in a way that depends on the power of the appliance. In this case, connectors are provided on the block. Their counterparts were purchased and attached to the strands of the cord. If the power of the electric stove were greater, then a clamp with screws should be used to connect the cores.

In accordance with the diagram for an electrical single-phase network, we connect the cord connectors to the terminals. We observe colors in accordance with the wires connected to the terminal block.

Then we clamp the power cord with a block located on the case. The force applied to the cord must not act on the terminals. The block, thus, protects them.

Then install the back cover on the stove. After that, it remains to connect the cord to the electrical plug. The socket was installed before the purchase of the electric stove. It is connected to ground, as well as to the phase and neutral wires. Therefore, after this last operation, the stove can be put on the prepared place and you can start using it.

When mounting the plug, you must first measure the part of the insulation to be removed. The stripped core should surround the screw shaft. It is necessary to obtain maximum area contact with each plug terminal. The cable must be clamped with a block located inside the plug body.

Connecting a powerful electric stove

The power of an electric stove with an oven and four burners is usually from 7 kW or more. For this reason, its connection is somewhat different from the process already considered for less powerful equipment. Since most four-burner electric stoves are connected to a single-phase electrical network, many of their models are equipped with a power cord already attached to the stove. In this embodiment, the task is simplified and comes down to connecting an electrical plug, which has a special design.

It allows the plug contacts to safely carry the operating currents of this appliance. But if you make mistakes when installing the cable, and as a result the contacts turn out to be unreliable, an accident with insulation melting and even fire is not ruled out. If the installation of the outlet has not been done before, and wires stick out from the wall to connect it, they must also be mounted with high quality.

To obtain reliable contact at the points of connection with the plug terminals, the stranded cores of the network cable must be tinned. For this, the veins are prepared by tightly twisting with pliers. This is done in order to fix the wires and the shape of the core. After twisting, it is bent in the form of a loop in order to obtain a large contact surface.

After trying on the loop on the screw with the clamping bracket, it is made flatter by squeezing with pliers:

Since the hinges will be tinned, they must fit into the screw with a bracket with gaps that take into account the solder layer.

If you need to mount a socket and connect the cores of the cable laid from the switch to its terminals, you must definitely check how the cores are connected to its terminals. They should not be attached in the same way as the self-tapping screw imitating the core in the image below. This is the easiest way to connect the core. But due to the small contact surface, the currents great strength the contact will heat up, and an avalanche-like process of increasing contact resistance will begin. As a result, both the wire and the socket will be damaged at best. But a fire could happen...

A modern electric stove can be a great alternative to the usual gas stove. Gone are the days when this household appliance looked bulky and consumed an exorbitant amount of electricity.

Today, the market for electric stoves is very diverse. In each model, manufacturers have tried to harmoniously combine functionality, compact design and energy-saving technologies.

In order not to turn to a professional electrician, you need to know how to connect an electric stove yourself. Most works, and sometimes the installation of such equipment in full, you can do it yourself.

Before you connect the electric stove yourself, you should find out its power, and also determine what type of network you need to connect to. Most private houses and apartments are equipped with a common network of single-phase wiring (220 volts). Three-phase lines are less common.

Tabletop electric stoves and individual ovens have a power of less than 3000 watts. They can be connected via a plug (13 Amp) and a socket or via a fused connector.
Electric stoves with an oven have a power of more than 3000 watts. Their connection is carried out through a separate wiring that goes directly to the electrical panel. This type of wiring is called a radial network.

For this type of network, the appliance is connected without an outlet to increase security. The power circuit is lengthened, a fuse is installed. Regarding it, you can (and even need) to consult an electrician. He will tell you whether it is worth replacing the traditional mini-machine with a fuse of this type.

A separate breaker with a fuse is mounted in the electrical panel or an existing free block is used. It must have a fuse. When installing a knife switch, make sure that tubular fuses are suitable for it.

The radial network is selected as follows:

stoves up to 13.5 kW - 4 sq. mm;
up to 18 kW - 6 sq. mm.

Protection is carried out by a 30 amp fuse or a 32 amp mini-machine. Three wire wiring. One of the cores is used as a ground.

We figure out how to properly connect the electric stove to the radial network

Do-it-yourself electric stove connection diagram in this case should be done in the following order.

Features of installation via connecting device

The procedure for this installation is as follows:

If the switch block goes directly to the spare block of the electrical panel, the red core of the wire is connected to the block itself (this is a phase), the black one to the neutral bus, and the ground wire, respectively, to the ground bus (marked with yellow-green cambric).
The second connection option is through a switch equipped with a fuse. It is attached near the electrical panel with screws.

The wires from the stove are connected to the terminals as follows:

a core with red insulation is attached to the phase;
black - to neutral;
the ground conductor is connected to the corresponding terminal (marked with a two-color cambric).

It is connected to the circuit breaker using two double-insulated stranded wires. Section 16 sq. mm (you can take wires thinner, by 10 sq. mm and connect with shorter segments of these wires). The black wire is attached to the neutral terminal of the switchboard and switch (N). Red to phase (L). Grounding from a stranded wire of the same length is fixed on the terminal in the corresponding place of the shield (yellow-green color).

Then the fuse is installed and the cover of the electrical panel is closed.

Attention! It is impossible to connect to a common terminal in the same way as it is impossible to power a new network until the installation is checked by a professional electrician and they issue a conclusion on compliance with all technical standards. This document is submitted to the electric company along with a request to connect to its network.

Mounting methods for different circuits

When installing with an outlet, everything is much easier. A cable is used to connect an electric stove with a special connector - a pair of sockets and plugs (RSh-VSh). It is produced in two types: for hidden and.

Plates come with a power of 220 and 380 volts. The connection diagram must be indicated by the manufacturer to ensure the correct connection of the network wires to the plate terminals. This schematic drawing is often located on the back of the device, or in the instructions for it.

On a note. In the diagram, the terminals for the phases are indicated: L1, L2, L3; neutral ones are indicated by the letter N. Directly in the terminal box, the phase is marked with numbers: 1, 2, 3; neutral is 4 and 5.

The jumper between the phase terminals was initially set by the manufacturer "by default" to connect the electric stove to a single-phase network.
For a three-phase connection of the electric stove, the jumper is removed. The order in which the wires are connected to the phase terminals does not matter.
For two-phase wiring, a jumper is installed between terminal 1 and 2. One phase is connected. The second is attached to the clamp number 3.

An example of a single-phase connection of an electric stove can be seen in the figure.

The principle of installation with all the variety of plates on the market is standard. Built-in, ordinary household and even industrial electric stoves are connected according to one general scheme. Minor nuances are due to the number of phases in the network. Understanding this is quite easy. Therefore, in fact, any owner will cope with the connection of the electric stove.

Video about connecting an electric stove with your own hands

Electric stoves have long been part of our everyday life, but, unfortunately, not everyone knows how to connect them. So, if you have purchased one of these stoves and are going to connect it yourself, this article will help you with this. In it, we, step by step, will try to explain how to do it competently, and most importantly, safely!

It is also worth noting that although electric stoves are considered household, they consume quite a lot of power - this should be taken into account both during installation and during further operation. heating appliances at home.

Before installation, carefully read the contents of the installation instructions. If any points have caused you doubt, then it is better to entrust the installation to a qualified electrician. Remember that the manufacturer's warranty does not apply if the electric stove is connected in violation of the rules and regulations for the installation of electrical equipment.

We suggest considering how to choose the right accessories for installation: cable, plug, socket, circuit breaker. Connect the electric stove and oven to a single-phase, two-phase, three-phase power supply network with a voltage of 220 and 380 Volts with your own hands.

Independent connection of the electric stove

Before starting any work on connecting electrical equipment to the network, you need to carefully study the technical data sheet of the product, which must be attached, as well as familiarize yourself with such regulatory documents as PUE 7 edition and PTEEP.

Step-by-step instruction connection of electric stoves electrolux ekc (electrolux), zanussi (zanussi), hansa (hansa), gorenje (combustion), bosch (bosch), ariston (ariston), beko (eyelid), hotpoint, indesit (indesit), greta, kaiser (kaiser ), aeg, nord ep, samsung to mains:

Step 1 - Power cables, circuit breaker and RCD

The power supply of the electric stove must be carried out by an independent cable that goes directly to the switchboard of the apartment. For laying the cable from the shield to the socket, you can use cable brands: VVG; VVG-ng; PVA; SHVVP. And from the outlet to the stove, it is better to connect with stranded wires, such as PVA or KG, which are more resistant to kink during repeated bending during operation.

The cross section of the cable depends on the mains voltage, the number of phases and the power consumption. Knowing these parameters, you can choose the appropriate cable from the table. It is better to take the cross section of conductors with a margin of one order of magnitude more.

Table: selection of cable section

The connection must be made from a separate circuit breaker. The rated current of the machine must be higher by one rating than the current consumption of the electric stove.

All characteristics of the electric stove can be found in the technical documentation that is attached with the purchase, they are also indicated on the case. The time-current characteristic of the circuit breaker must be group C.

It is also desirable to install a residual current device (RCD), which will protect a person from damage. electric shock, if you accidentally touch the faulty equipment. The RCD is installed next to the circuit breaker, and connected after it. Its face value should be an order of magnitude less than the machine. The leakage current to earth is not more than 30 mA. All screw terminals must be carefully clamped, as a large current will pass through them.

Step 2 - Installing the Outlet

Far from every apartment, the kitchen has a power outlet designed to connect powerful appliances that consume more than 3 kW. This is usually a single-phase power outlet that is rated at 32 A or 40 A.

We suggest considering how to choose and install an outlet for an electric stove:

The socket must be made of quality materials and ensure reliable electrical contact.
The number of contacts must correspond to the number of wire cores. It is forbidden to connect the wires together by connecting them to the same contact.
Use only copper cable to connect the socket.
The cable cross section must comply with the table above.
The socket is installed on a flat, non-flammable surface.
If you have Brick wall, it is advisable to install the overhead socket on a special lining, this will prevent the base of the socket from cracking during installation.
Do not install the outlet too close to hot surfaces, washstands, iron pipes, window and door openings.
When replacing an old outlet, make sure that the insulation of the wires is not damaged and there are no signs of overheating of the cable.
The colors of the wires must match the purpose of the wires, both in the socket and in the plug.
All screw terminals must be properly fastened. Stranded wires should be pre-soldered with a soldering iron, at the point of their attachment to the socket contacts.
After installing the outlet, make sure the wires are connected correctly. Use a multimeter to check for short circuits.

Turn on the circuit breaker in the apartment's switchboard. Use a multimeter to check the presence of voltage at the phase contacts of the socket.

Step 3 - Open the back panel of the stove

To connect the cable to the electric stove, on its back side you need to find and unscrew a small cover that covers the wire terminals.

Back wall household stove

Step 4 - Attaching the cable

After you have removed the cover, you need to fix the cable. This is done in order to avoid accidental pulling of the cable from the plate. Insert the cable and fix it on the stove body in a special clamp.

Hole for wiring ZVI cable

Step 5 - Installing the Copper Jumpers

Depending on the number of power phases, the wires are connected in different ways. In order to properly coordinate the connection of the plate to various power networks, special copper jumpers are included with the terminal block. According to the scheme you have chosen, install the jumpers in the block and tighten the screws where the wires will not be connected.

Connecting wires to a household stove

Step 6 - Connect the Wires

It is very important to correctly connect the wires on the terminal block! In the documentation and often on the case itself, near the cover, there is a connection diagram with various types supply network. According to the diagram that suits your case, connect the wires to the terminals. The color of the wires must match the connection in the plug and socket. The first one connects the ground wire - yellow-green, then the neutral wire - blue. Then phase wires, brown and two black. The main thing here is not to confuse anything so as not to disable the equipment.

We connect the isolated neutral and ground with a jumper

Step 7 - Closing the Panel

After connecting all the wires, check the connection diagram again, make sure there are no errors. Tighten the clamping screws well. But remember: in all plates, the connector is made of fragile material, do not use much force, otherwise you may damage it. Now you can close the cover and tighten the mounting bolts.

Step 8 - Connecting to the Network

Before connecting the oven to the mains, make sure that the circuit is assembled correctly, all current-carrying parts are closed. Turn on the machine and RCD, check for voltage at the outlet. Plug in the electric stove. According to the instructions, make sure that all its functions work correctly.

Video: video instruction for connecting an electric stove

Connecting the stove in a single-phase network

Unlike a private house or manufacturing enterprise, in the apartment there is no way to connect the electric stove to a three-phase network. Therefore, we will consider a single-phase connection used in apartments. Most stoves have the following wire terminals: L1; L2; L3; N1; N2; and ground contact.

To connect such an electric stove to a home single-phase network 220 V is necessary:

put a jumper between terminals L1 and L2, L2 and L3,
connect a phase wire to L2 - brown;
leave a jumper between terminals N1 and N2;
connect a neutral wire to N2 - blue;
to the grounding contact marked with a special icon, connect the ground wire - yellow-green.

The number and name of the terminals may differ, specify these data in the documentation for the device.

Independent connection of the electric stove

Step 1 - Power cables, circuit breaker and RCD

Table: selection of cable section

The connection must be made from a separate circuit breaker. The rated current of the machine must be higher by one rating than the current consumption of the electric stove.

It is also desirable to install a residual current device (RCD), which will protect a person from electric shock in case of accidental contact with faulty equipment. The RCD is installed next to the circuit breaker, and connected after it. Its face value should be an order of magnitude less than the machine. The leakage current to earth is not more than 30 mA. All screw terminals must be carefully clamped, as a large current will pass through them.

Step 2 - Installing the Outlet

We suggest considering how to choose and install an outlet for an electric stove:

The socket must be made of high quality materials, and provide reliable electrical contact.
The number of contacts must correspond to the number of wire cores. It is forbidden to connect the wires together by connecting them to the same contact.
Use only copper cable to connect the socket.
The cable cross section must comply with the table above.
The socket is installed on a flat, non-flammable surface.
If you have a brick wall, it is advisable to install the surface outlet on a special lining, this will prevent the base of the outlet from cracking during installation.
Do not install the outlet too close to hot surfaces, washstands, iron pipes, window and door openings.
When replacing an old outlet, make sure that the insulation of the wires is not damaged and there are no signs of overheating of the cable.
The colors of the wires must match the purpose of the wires, both in the socket and in the plug.
All screw terminals must be properly fastened. Stranded wires should be pre-soldered with a soldering iron, at the point of their attachment to the socket contacts.
After installing the outlet, make sure the wires are connected correctly. Use a multimeter to check for short circuits.

Turn on the circuit breaker in the apartment's switchboard. Use a multimeter to check the presence of voltage at the phase contacts of the socket.

Step 3 - Open the back panel of the stove

To connect the cable to the electric stove, on its back side you need to find and unscrew a small cover that covers the wire terminals.

Step 6 - Connect the Wires

It is very important to correctly connect the wires on the terminal block! In the documentation and often on the case itself, near the cover, there is a connection diagram with various types of power supply. According to the diagram that suits your case, connect the wires to the terminals. The color of the wires must match the connection in the plug and socket. The first one connects the ground wire - yellow-green, then the neutral wire - blue. Then phase wires, brown and two black. The main thing here is not to confuse anything so as not to disable the equipment.

Connecting the stove in a single-phase network

Unlike a private house or a manufacturing enterprise, in an apartment there is no way to connect an electric stove to a three-phase network. Therefore, we will consider a single-phase connection used in apartments. Most stoves have the following wire terminals: L1; L2; L3; N1; N2; and ground contact.

To connect such an electric stove to a 220 V single-phase home network, you must:

put a jumper between terminals L1 and L2, L2 and L3,
connect a phase wire to L2 - brown;
leave a jumper between terminals N1 and N2;
connect a neutral wire to N2 - blue;
to the grounding contact marked with a special icon, connect the ground wire - yellow-green.

The number and name of the terminals may differ, specify these data in the documentation for the device.
