What you need to connect the electric stove. Rules for installing the outlet for an electric stove. Circuit Breaker and Safety Shutdown Device

Before you do something yourself, you need to decide which type of slab you will work with. Electric plates are produced in several versions: ceramic, induction, built-in and others. Also differ in the types of burners built into the cooker: express-ring, automatic ring with a white circle, a conventional cast-iron ring. When you choose the optimal option for you and buy it, then you can start connecting the electric cooker.

Whatever you do, the most important rule when installing a plate is to turn off electricity. Such a trifle can easily fly out of your head, but the consequences will be terrible if you do not remember this little detail in time.

Necessary tools. In order to make the installation of an electric stove, it is recommended to acquire some tools, namely:

Screwdriver. Its purpose is to attach the wires to the terminals.
Indicator. The device checks whether there is a phase on the network, or not.
Electroblade. They are looking for a "zero wire".

Determine the capacity of electric cookers

Smaller in size electric cookers, which have a power of not more than 3 kW, will be correctly connected using a plug and socket with a current of 13A. Sometimes adapters and fuses are required.

If the current of the electric stove exceeds the value of 3 kW, then connect it to the radial circuits. A circuit is a wire that has a connection to a switchboard. Further, at a distance of 2 meters from the plate, a connection unit is installed, which connects the shield and the electric stove.

Information about the scute

It is worth mentioning separately about the shield. Check the standards listed in the manual yourself. The cable should have 3 veins, and the cross-sectional area for copper should be at least 4-6 sq. M. If this is not the case, then a replacement is required. The current must be approximately 40-50 amps.

Pay attention to the model of the shield and its characteristics. The letter "L" is a phase, the letter "N" is zero, respectively, and the earth is "PE".

If the network is single-phase, then the correctly executed sequence of actions will be:

We install and manufacture a socket with 3 contacts.
We attach a power plug to the wire. There are 3 wires in the wire, 3 contacts in the plug.
The wire is connected to the electric stove and plugged into the socket.
The electric stove is set according to the level.
Check the work of the plate.

Working with a three-phase network

Often this situation is observed in houses of country type. In that case, how correctly to connect an electric stove? In advance, a switch is built into the wall, which includes 3 poles. Marking on the cover of the plate itself inscriptions on it will prompt you how to arrange the outlet. In any case, in relation to the wall, it should be placed horizontally. Next we make the connection according to the colors of the wires. You will do everything right, guided by the principle that colors should match each other.
It is necessary to buy an outlet with the same current as it would safely function with the cooker. The number of amperes that consumes an electric stove is calculated by the formula: the power of the plate is multiplied by 1000 (that is, the number is simply converted from kilowatts to ordinary watts), and then the resulting value is divided into mains voltage.
In order for the network to load evenly, a copper five-wire wire is laid in the electrical panel. To the outlet and the plug, it is connected with a cable of the brand "PVS 5x2.5". Between contacts 1,2,3 the factory-installed jumper is removed. They are connected with the opposite phases L1, L2, L3. To the contact N1, N2, zero is attached, and earth is connected to the remaining PE contact.
Often, the appliance is attached to the installation scheme, where everything is correctly and correctly painted. With her it will be much easier to figure out how to connect the electric stove yourself.
Check, once again, the work of the plate.

Do not prematurely dispose of the packaging. In case the goods are defective, this will enable you to exchange it.
Inspect the electric stove so that there are no scratches and chips on it.
If the apartment is old wiring and there are used aluminum wires, they should be replaced by copper ones.
From the switchboard to the socket, a separate wire is laid, designed to connect only the electric stove.
To avoid unpleasant situations when installing the plate, use a rubber mat under your feet.

The fact that the connection of the gas stove should be entrusted to professional masters, probably everyone knows. But with the electric cooker the situation is somewhat different. Many believe that it is easy enough to plug it in and you can "wash your hands". In fact, this is not so. The electric stove is a very powerful electrical appliance, therefore, when it is connected independently, it is necessary to strictly observe a number of requirements. We'll talk about them in this article.

General requirements for connection of electric stoves

Despite the abundance of various models and brands of electric cookers (hansa, burning, etc.), the general requirements for their connection are almost identical. A small difference exists only in the connection of plates at 220 and 380 volts.

Regardless of the brand, the connection scheme for all plates is the same

So, here are the basic requirements for connecting an electric stove:

for it, a separate electrical wiring line must be installed, equipped with a safety device;
the plate should be connected to electricity either directly, or through a terminal strip or a special outlet;
the connection should take place taking into account such parameters as "phase", "zero" and "ground".

Let's consider each of the above items in more detail.

Separate posting line

Most apartments, especially new buildings, are equipped with a separate power line for the electric stove. But if in your home such a line is not provided, then before connecting it you need to lay it.

For a power supply line of an electric stove, a copper three-wire wire, with a cross section of at least 6 millimeters, is suitable.

It is better to use a multicore cable to connect the plate.

A safety automatic device, with a capacity of 25 to 40 A, must be installed on the line.

The power of the machine is selected in accordance with the power of the plate

More precisely, the required power of the machine can be found in the instructions accompanying the plate.

The line should be equipped with a differential automaton or an emergency shutdown unit.

Connecting the cable to the plate

Some models are not equipped with a power cable, so you'll have to connect it yourself.

To do this, remove the protective cover on the back of the plate. As a rule, it is bolted.

Before starting work, the cover must be removed

Connecting the electric stove can be single-phase (220 volts), two-phase or three-phase (380 volts). It is very important to know which of the wires is connected to the phase. To do this, you must first use an electric tester.

Before connecting the slab, the network must necessarily 'ring'

Clamps of the electrical box terminal box are marked with the following:

L1, L2, L3 - phase terminals. As a rule, these are terminals 1,2 and 3;
N - zero terminals. These are terminals 4 and 5;
And the ground terminal marked with a special icon.

Most plates have jumper settings between the terminals. If these jumpers are not present, then for a single-phase and two-phase connection, they will have to be manufactured independently. To do this, you can apply small pieces of cable. For this purpose, use a three-core cable (for single-phase connection) or five-core (for two- and three-phase).

Single-phase

The jumpers between terminals 1, 2 and 3 are installed. The phase wire is connected to terminal 3. Jumper wires are inserted between terminals 4 and 5. A neutral wire is connected to terminal 5. And the remaining wire is to the ground terminal.

Single-phase jumper connection manufacturer

The diagram of single-phase connection is shown in the following figure.

The jumpers are installed between all terminals

Two-phase

Jumpers are installed between terminals 1 and 2. And to 2 and 3 connect the wires of the respective phases. Connect the neutral wires to terminals 4 and 5. To the earth terminal is the ground wire.

For a two-phase connection, two jumpers

Three-phase

In this case, the jumpers between the terminals are not set. The ground wire is output separately.

Wires are attached to terminals without jumpers

All wiring connections are made using special clamps.

Plate-to-mains connection

The best way is to directly connect the plate to the safety device. This makes it possible to avoid unnecessary connections that can overheat, which lowers the level of security.

Absence of unnecessary connections is considered the most secure

But if you want to have the possibility to disconnect the stove from the general power supply, you can install it using a terminal strip or a special outlet.

The terminal strip is fixed to the wall, after which the wires of the power supply line are connected to it on one side, and the power cable of the electric stove on the other.

Make sure that the terminal board corresponds to the power of the plate

IMPORTANT! When connecting to the terminal strip, make sure that the wires of the corresponding color are connected to the same terminals as on the plate itself.

Connecting via a power outlet

To connect the electric stove, you need to install a special power outlet with ground.

Electric stoves are increasingly included in the everyday life of urban residents. This is due to the expanded capabilities of such equipment and the ban on the supply and installation gas system in high-rise buildings. Let's consider how to properly connect the electric cooker.

Types of electric stoves

There are several classifications.

According to the material of execution:

Enameled. in such models there are two types: pancake (cast iron), spiral. There are combined options with connection to gas and electricity.
Glass-ceramic. The heating element in such plates is a spiral, corrugated tape, halogen lamps.
Induction. They can be attributed to a subspecies of glass-ceramic plates, but instead of a heating element, an electromagnetic coil is built in.

By design:

Stand alone. This technique can be equipped with an oven.
Desktop. Popularity is due to the compactness, mobility. Often the connection of an electric cooker of this kind is used in the country. There are models with built-in oven.
Built-in. This technique has gained immense popularity due to its ergonomics. The existing range allows you to fit such equipment into any interior. Typically, this technique is divided into a cooking surface and an oven.

By the number of contacts: from one to six.

By intensity of use:

household;
professional.

By power consumption:

low-power (with the ability to connect to a 220 V network);
powerful (connection of an electric plate with own hands to 380 V).

By type of management:

mechanical;
sensory.

As you can see, along with the classic models in our time you can buy and "smart" equipment.

Consider how each type of household equipment of such a plan works.

Design features. Principle of operation

Each electric stove has its own design features.

Enameled

The heating element is a spiral made of metal with a high specific resistance. The principle of operation is based on the release of thermal energy as the current passes through the resistive heating element. This is typical for solid (cast-iron) models, and for spiral ones. There is only one difference: in the first variant the heating element is inside the ring.

Glass-ceramic

The principle of operation is the same as in enamel plates, with the only difference that the heating element can be not only a classical spiral, but also a corrugated ribbon, halogen lamps.

Induction

But this technique is different in principle. The heating element is an electromagnetic coil, which, passing a current through itself, creates a field. It, in turn, forms induced high-frequency currents in the dishes. Guidance occurs due to lines of force through the bottom of the dishes. Therefore, for such plates you need specialized kitchen utensils.

Apparently, the principle of operation of induction models differs significantly from other options. Which technique is better?

Advantages and disadvantages

The connection of the electric plate to the network is inevitable regardless of the type. Let's consider each variant from the point of view of merits and lacks at operation.

Enameled

They differ in simplicity of construction, moderate cost and easy repair at a low price. For washing, ordinary, affordable cleaning agents are used. As for the shortcomings, an open spiral - the danger of getting an electric shock at the time of operation, often requires the replacement of a spiral. For cast iron minus - a long time of heating and cooling, respectively, increased electricity costs.

Glass-ceramic

The cooking surface has a high thermal conductivity, which makes it possible to heat dishes and food much faster than the classical version does, and this significantly reduces the cost of electricity. The possibility of setting the exact heating. The heating element is protected by a glass-ceramic coating, which significantly extends its life. Care of the surface is much easier, it has a perfectly flat plane. The price of such a plan is much higher, more expensive and more difficult to repair, abrasives and cleaning powders are contra-indicated for washing, special dishes with a flat, smooth bottom are required for cooking. If the model has low sides, then when it spills food, it can leak to the floor.

Induction models

In terms of energy savings, the most advantageous option. The burners start to heat up only when there is a pan on the stove, if it is removed, an automatic shutdown occurs. Otherwise, this type of technology has the advantages of glass ceramic models, but the price for repairs and the equipment itself is much higher. Moreover, to the dishes one more requirement is required - magnetic properties.

When choosing a particular model, you should pay attention to the technical data, to find out whether it is possible to connect the electric plate to the existing wiring (outlet).

Important characteristics when choosing

Acquiring new equipment, should rely on a number of technical data:

Dimensions. It is necessary to measure 3 parameters: width, depth, height.
Power consumption. Depending on the manufacturer, model, availability of the oven, it can range from 1.5 kW to 8 kW. It is better to take a class no lower than "A". Such equipment will save on power consumption. These data are indicated in the passport for the equipment.
Equipment. The presence of a cable and a plug from the factory. Most often they are absent.

All other parameters are selected based on personal preferences.

Having identified with the model, perform an audit of the existing electrical wiring. If the power of the equipment does not coincide with the section of the cable, it will be necessary to replace it.

Terms of connection

Modern plates have a lot of power, so before you buy the chosen model, you need to evaluate the existing wiring system. Most often this technique is sold without a plug and wire, because the connection of the plate electric plants are provided in three ways. The required one is selected at the installation site, to which a number of requirements are made.

It is necessary to have a free end of the wire in place of up to 2 meters. This will allow further movement of the equipment for repair work or for washing the floor under it.

Must comply with the declared power consumption. Even better, if there is a reserve. This is especially true for intensive use of cookers and ovens.

The cable must be integral, free of adhesions and joints.

The wiring for the plate is supplied separately, and a separate automaton must be provided in the shield.

Regardless of the model, household appliances are often connected through a power outlet. But first, let's see what cable is needed to connect the electric cooker.

Wire selection

In multi-apartment buildings, single-phase connection of slabs is most often envisaged, so builders leave a free end of the wire with a cross-section of 4 mm 2. Such parameters are suitable for plates with a power not exceeding 13 kW.

If the wiring is not provided, it is obsolete, then it is necessary to select the correct wire for connecting the electric cooker, which must meet the following parameters.

The veins should only be copper (established by the regulatory document of the PUE 7.1.34).

The number of cores is important. For apartments most often there is a single-phase connection, the cable for it is taken three-core (phase L, zero N, PE ground). In private houses, a three-phase, five-core cable (three phases L1 L2 L3, zero N, PE ground) can be provided.

For a 220 V network, there must be at least 6 square meters. mm, according to SP 31-110-2003 (item 9.2). This is an average value, the value can vary in both directions, depending on the technical data of the plate itself. For three-phase installation, the cable must be a five-core section of at least 2.5 square meters. mm. Determine the cross-section of the cable by using special calculators or tables.

Cable brand is required VVG; VVG-ng; PVA; ShVV. To connect the plate to the network, you can use PVA or KG.

Wire laying must be carried out separately.

It is necessary to have a separate machine in the shield. RCDs for regulatory documents can not be set for household appliances. But considering that the electric stove is an increased source of danger, it is better to provide. The automatic machine for a single-phase installation is selected with a rated current of 32 A (RCD at 40 A), for three-phase - a three-pole automatic machine at 16 A, a RCD of 25 A.

The cable for connecting the electric cooker must be laid in a separate line, it can not be hung with other points (sockets, lighting). Most often, hidden wire is used.

Selection and installation of power outlet

Determining which cable is needed to connect the electric stove, choose a power outlet.

It must meet the following requirements:

the rated current of the socket and plug must correspond to the parameters of the machine and the number of wires of the wire;
the form of the power outlet depends on the method of laying the cable (hidden or open);
should buy a product made of high-quality non-combustible materials.

Consider a number of points for installing the outlet:

installation is carried out on a flat, non-flammable surface;
do not install near hot surfaces, heating system, water supply;
the connection of the conductors must be done according to the scheme, without confusing the colors;
screw terminals must firmly fix the contacts;
after installation, check for a short circuit.

After installation, the sockets begin to install the equipment itself.

Installation and connection of the electric cooker

After delivery of the equipment, it should be unpacked and checked for completeness, no visible discard. Before you start, it is worthwhile to carefully study the instructions and the wiring diagram. Remove unnecessary components, set by level.

Unscrew the panel covering the terminals on the back of the equipment. There are also duplicated three connection schemes.

As already mentioned earlier, rarely do manufacturers supply household models with a wire and power plug. Therefore, the purchase of a cable and a power outlet with a plug is carried out independently. Let's consider three ways how to make connection of an electric gas cooker with your own hands.

Single-phase

With this installation, the phase (red) is connected to terminals L1, L2, L3. Since the wire is three-core, copper pins are installed on the pins (they come complete with equipment). On N1, N2 set a zero (blue) and a copper jumper. PE - earth (green). All the contacts are tightened, the cable is fixed with a special clamp. The lid is installed back. There are 3 contacts in the socket: upper - ground, two lower - phase and zero.

Three-phase

It differs from the previous phase connection. There is a wire for each terminal. It is necessary to observe the color according to the scheme. All the rest is made analogous to single-phase.

Two-phase

At phase L1, L2 we put a jumper and connect one of the ends of the phase, on L3 - the second. The rest of the installation is similar to the previous two.

After installation, it is necessary to perform a test run according to the instructions on the equipment.

Connecting the electric cooker independently will not cause difficulties, if you follow the instructions and safety during installation. All work must be carried out with a de-energized system.

Features of mounting of some brands

Connection can be made both on a single-phase circuit, and on three-phase. It all depends on the power supply. All the steps are described above. The connection also does not have any features and is implemented according to the general scheme.

It is worth paying special attention to the warranty obligations. Incorrect installation can lead to equipment failure, and this will be the reason for the refusal of the service center to carry out a free repair. Therefore, if you are not confident in your abilities, it is better to carry out installation by hands of a specialist who has a special license for such work. In the passport a mark is placed on the connection in case of misunderstanding.

Connecting the gas cooker

The design of this technique makes it possible to use both the electrical network and the gas. There are two versions: with mounting to the gas distribution network and gas bottle. It should be noted that for the use of gas equipment in apartment house, in which such a system is not provided, a special permit will be required.

The rest can be noted two important points: connection to the gas distribution network must be performed by a specialist gas supplier company, which places an appropriate mark in the passport. In the future this organization carries out maintenance of the equipment. Installation to the network does not impose special requirements. For a sufficient outlet with 16A grounding.

Conclusion

As you can see, you can independently connect the household electric cooker yourself.

But if you are not confident in your abilities, it is better to turn to a specialist. In the future, this will reduce the cost of paid repair of equipment due to improper installation.

So, we found out how to connect the electric (gas) plate with your own hands.

Every year more and more people decide to connect the electric stove. This is not surprising. Modern technologies used in their creation, can achieve considerable savings.

Imagine that you have already purchased an electric stove, and you need to connect it. In this case, you must first read the instructions carefully. It is there that indicates the working connection diagram.

Attention ! Electric stoves consume large amounts electric power in comparison with other household appliances, and this must be taken into account when connecting the scheme.

Algorithm of connection

Before proceeding to the direct connection of the electric cooker according to the scheme, it is necessary to familiarize yourself with a number of documents:

PUE 7,
PTEEP,
technical certificate.

Only after this you will be able to correctly use this instruction. Otherwise, you run the risk of not only losing the warranty on the electric stove, but also putting yourself at risk.

Step 1. Select the wires

The power wire according to the scheme must be independent. Simply put, it must be directly put into the switchboard. Otherwise, the wiring can simply burn out, thus provoking a fire.

If you do not have a dedicated line in the house, then you can use these types of wires:

VVG-ng,
SHVVP.

In turn, to connect the appliance from the socket according to the scheme, you need to use a cable type PVS. If you can not find it, then the KG will do. By the way, the latter has much more resistance to kinks. During operation, it can flex many times. Harm from this will not happen.

When you select the cross-section of the cable for connecting the electric stove, you need to take into account three main parameters:

number of phases,
mains voltage,
power consumption.

Just look in the table below and choose the cable that is suitable for connecting the electric stove. In this case, it is better to provide a small margin of power, since the differences in the network - this is common.

Also, when you connect the electric stove according to the scheme yourself, you need to know about some of the nuances. First, all operations must be carried out independently of the circuit breaker. Secondly, the current rating should be higher by one unit than the consumption of the device.

Technical characteristics of the electric stove you can find in the relevant documentation, which should go to the device in the delivery set. Also all parameters are indicated on the case.

Attention ! Circuit breaker must belong to the group C.

When connecting the appliance according to the scheme it is necessary to take care of the presence of an RCD. It will protect you and your family from electric shock during the operation of the device.

The RCD must be installed close to the auto-switch. The connection of a residual current device is possible only after the installation of the circuit breaker. Pay special attention to screw terminals.They must be securely fixed.

Step 2. Make the outlet

Ideally, you should already have an outlet in your kitchen, through which you can connect the electric stove according to the scheme. But unfortunately, not all apartments are equipped with connectors of the right capacity, therefore sometimes it is necessary to take care of it independently.

Attention ! You need a power outlet that can supply power to electrical engineers with a capacity of over 3 kW.

In most cases, a single-phase outlet is installed in the kitchen. It is more than enough to ensure the connection of the electric stove according to the standard scheme. The minimum rated current must be at least 32 A. Ideally, you need 40.

The outlet that you will use to connect the electric stove according to the scheme should be made with quality materials. Electric contact must also be ensured.

It is very important that the number of cores is the same as the number of wires. Under no circumstances can the wires be connected together, so that it is possible to connect to one contact. This can lead to a fire hazard situation.

When connecting, you can only use copper wire. In this case, the cross-section of the wire should correspond to the table indicators. The outlet should be installed on a flat surface. In this case, materials with high combustibility should not be nearby.

Advice! When installing on a brick wall, it is advisable to use a gasket so that the base of the outlet does not crack.

Do not install a socket for connecting an electric cooker according to the scheme near the washstand. This does not comply with the safety rules. Spray can get on the bare cable and cause a short circuit.

Also, the socket should not be installed too close to the iron pipes. The same applies to door and window openings. The safe operation of the device depends on the correct choice of location for installation.

When you have completed the installation of the socket for connecting the electric stove according to the scheme, check the insulation. Cables should not be damaged. Only then turn on the stove.

Attention ! Ideally, the colors of the wires in the plug must match the colors of the cables in the outlet.

Pay special attention to the screw terminals, they must be fixed properly.Moreover, when installing the outlet, to connect the electric stove, each multicore cable must be additionally added. The soldering should be done where they are attached to the contacts.

In how correctly you connected the wires, you will be able to verify the multimeter. As soon as the preliminary check is completed, you can turn on the circuit breaker.

Step 3. Connecting to the plate

To connect the electric stove to the power cable, you, of course, will need a circuit. The exact drawing of the connection must be in the technical passport. After you find it you will need to find a small cover on the back panel and unscrew it. Below it you will find the terminals of the wires.

Now you can fix the wires to connect the electric stove according to the scheme. But before that you need to fix all the cables. Otherwise, by a careless movement, you just grab them.

Attention ! There are special clips for the fastenings on the body of the electric stove.

Wiring depends on the number of phases. To connect, you need to use copper jumpers. Usually they go together with the terminal block. According to your scheme, establish connections. Then tighten the screws.

Usually in the documentation or on the cover itself there is a circuit with which you can connect the plate. Wherein the colors of the cables to be connected should ideally match each other.

First of all, you need to connect the ground. Usually this wire has a green color (a mixture of yellow and green). After that, you can connect the neutral. The blue cable is connected to the third one. Only after this you can go to the phase wires. The sequence is as follows:

brown,
the black,
the black.

During connection, it is necessary to maintain extreme caution, since incorrect contact can lead to failure of the plate or wiring. At the end of the work, the lid is closed.

General schemes of connection to the network

Perhaps this is the most simple circuit connections to single-phase network, in order to connect the power you need:

Install jumpers to terminals L1 and L2, L2 and L3.
To L2, connect the brown wire to the phase.
Install the jumper on N1 and N2.
Attach the neutral to the N2.
A ground wire is output to the ground terminal.

In doing so, you must remember that this is general scheme. In many of the schemes that come with the documentation, there may be other terminal names. Moreover, even their number can be different.

If you need to connect the slab to the three-phase network, then the circuit will be slightly different. You will have three phases, which you just need to connect to the three terminals L1-L3. At the same time, during installation no jumpers are needed. N1 and N2 together with the PE are connected to the advisory contacts.

In this article, we will consider the connection schemes for electric stoves, as well as practical guidance on how to install such a stove in-house. In addition, you can take help, and inexpensively order this service. But if you are used to doing everything yourself this article is for you. After thoroughly reading the article to the end, you will easily cope with this task.

All household appliances consume electricity, and naturally, when it comes to the electric stove, it is clear that the connection of such devices requires a mandatory grounding. At the moment, rosettes and plugs of the RSh-VSh standard are used in the market. These connectors have a grounding contact. These outlets are produced both at 220 V and 380 V. They were designed back in the days of the Soviet Union, and are used, to this day, however, time has made its own adjustments, modifying them for hidden wiring.

Summary of the article.

Preparing to connect the electric stove.

Take your time, before you start work on connecting your electric stove, you need to read the instructions that came with it, namely, to look at the power consumption and the options for wiring. And also be sure that all security requirements and connection rules will be met. To do this you need:

Check the power cable. It should go directly from the electrical panel and have three cores for connection to 220V or five cores for connection to 380V. A grounding conductor must be required, in any case.

Check the circuit breaker. For an electric stove, a separate automaton for 25-40A should be installed in the switchboard, depending on the number of phases in the cable that is connected to the plate. If on 220V, this is usually 32A. If the 380V is usually a 25A automatic.

Check cable cross-section. This item is mandatory for those who have an old house with an old one aluminum wiring respectively. The fact is that in some old houses electrical wiring is not designed for the power of modern plates.

Table 1. To verify the conformity of the cross-section of the supply cable to the consumed power of the electric stove.

Cable cross section	Copper wires			Aluminum conductors
	Current, A	Electric cooker power, kW.		Current, A	Electric cooker power, kW
	Current, A	220V	380V	Current, A	220V	380V


			12,0

Check and mark the wires. Modern wiring makes this very easy, because the wires of the new sample differ in color, most often the ground wire is in isolation of green or yellow-green colors, zero blue, white, red, brown phase. Posting the old sample presents a difficult task, because all the wires in it are the same color, and therefore, to determine which wire is grounded, you will need to turn off the power supply in the apartment.

Next, using an ohmmeter, you need to check the wires, for this one probe needs to be fixed so that it touches the battery and water pipe, the second wire is checked. Resistance to grounding will be only a couple of tens of Ohms, while the remaining wires will show how much more resistance. In order to somehow distinguish the wires, you should mark them with multi-colored markers or a simple electrical tape, if it is at hand. If you have previously had an electric stove or a socket for it, a check is not required, since there is already everything connected up to you, at your terminals. Without wire testing and 100% detection of zero, ground and phase, the connection is prohibited.

Sockets and cable for connecting the electric stove.

Depending on the chosen connection scheme 220V or 380V, we may need the following materials. Directly the socket itself, and a piece of cable. From the tool set of screwdrivers, knife, multimeter and indicator screwdriver.

The choice of sockets for connecting the electric stove. The design of the finished pair completely and completely eliminates the possibility of an error in the connection of the electric stove. At the moment, Rosh-Shh sockets are manufactured in Ukraine, and this is bad for their quality. After all, they are designed to work with a power of 7 kW, while most of the electric stoves that are produced today are designed to work with capacities of 8-10 kW. Here we will benefit from the replacement of a pair of plugs and sockets, especially since in our time on the market there are remarkable sets of Belarusian production. They are made in modern design and are suitable both for domestic plates and for European ones, which most often do not have cords and plugs in the connection set.

Figure 1. Sockets for connecting the electric stove.

Belarusian connectors. The main advantage of the Belarusian connectors is the combination of their price and quality. Undoubtedly, they are more expensive than Ukrainian, but much cheaper than European counterparts. In their work, they can withstand large capacities, and are designed to operate more than 32A, in addition they are available in the market for both open and closed postings.

Connection via a box, without an outlet.

Figure 2. Terminal box for connecting the electric stove.

In modern homes, new buildings, special terminal boxes are increasingly used to connect electric stoves. This version of the connection is universal and unlike the sockets it is suitable for connection to both 220V and 380V.

In photo # 2, a three-core cable emerges from the wall and joins the corresponding contacts of the box (the contacts on the box are signed). Out of the box, a flexible (black) cable goes to the electric stove.

Choice of brand and cable section.

Cable selection. To connect an electric stove, we also need a three-core or five-core copper flexible wire length of 1.5-2 meters. I always take a cable of the mark ПВС-3х4 or ПВС-5х4. The first digit indicates the number of cores, the second digit is the wire cross-section.

Wiring diagrams for electric cookers.

Typically, having removed from the back panel of the terminal cover, you will find not only a row of copper jumpers, but also a circuit of three variants of connection located next to it. They are designed for three-phase, two-phase and single-phase connection to the mains. Next, we will take a closer look at all the existing connection schemes.

Figure 4. A sticker with options for connecting circuits for an electric stove. It is usually located on the back cover.

Wiring plan for an electric cooker at 220 V.

The most common option is to connect to a single-phase network. To do this, you need to install all jumpers in accordance with the figure. Namely, we put the two jumpers, which come in the kit, between the terminals 1,2,3 and connect the phase conductor L1 to them. Next, put a jumper between the terminals 4.5 and connect the zero wire N to them. There remains one terminal with the ground symbol, we connect the PE ground wire to it. It is desirable to observe the color marking, that is, to zero to connect the wire of blue color, to the ground yellow, green or yellow-green other colors to the phase contact.

Figure 5.

Note that on different models of plates, the location of the grounding contact can be either on the right or on the left. Therefore, when connecting the ground wire, be sure to check the presence of a ground symbol near the contact.

Figure 6.

Scheme of connecting an electric stove at 380V.

There are two options for connecting three-phase and two-phase. It is preferable to choose a three-phase version for uniform load distribution. For three-phase connection You will need an outlet for 5 contacts, and for a two-phase socket you can purchase a socket for 4 contacts.

Three-phase connection.

Figure 7. Scheme of connecting an electric stove at 380 V to a three-phase network.

Let us first consider a three-phase connection. Again we look at the circuit and in accordance with it we establish only one jumper between terminals 4,5 and connect the zero wire N. We then connect the phase conductors L1, L2, L3 to terminal 1,2,3. Connect the PE wire to the terminal with the ground symbol.

Two-phase connection.

Figure 8. Scheme of connecting an electric stove to 380 V in two phases.

In accordance with the diagram, connect the phase conductor L1 to terminal 1, install a jumper between terminals 2,3 and connect the phase conductor L2 to them. We install a jumper between terminals 4,5 and connect to them a neutral wire N. The PE ground wire is connected to the terminal with the grounding symbol.

Attentive readers probably noticed in the picture that there is another option for connecting to three phases (on some models) without using zero. This option was created for America, in no case do not apply it in Russia. The fact is that in this circuit the mains voltage should be 110V.

The final stage, verification.

Before you turn on the electric stove in the outlet, you must turn on the machine and check the correct connection on the outlet. Verify with a test screwdriver that the phase wire is at the phase terminal. Check again that the plugs on the plug are connected, right. The resistance between the grounding contact on the plug and the plate body must be zero. After you can connect the plug and slowly put on the plate all modes of operation, in order to ensure that the wiring can withstand the load. That is, the machine does not turn off, and the cable does not heat up. So all good! You've done it!

The cooker, as practice shows, is more of a stationary device, and once you install it, you will not change its place every day or even once a week, and therefore there are schemes for connecting the electric stove directly, without a plug and socket. As a rule, in this case the electric stove is connected through junction box with a carbonate or ceramic terminal strip.
