Connection of electric and induction hobs

When buying a separately standing electric stove, in most cases, it is enough to simply turn on the fork in the outlet for its connection. But many acquire not a complete set, but only the upper part of it. the hob panel.

We offer to consider how to connect the Electrolux hob (electrolyx), Zanussi, Bosch (Bosch), Gorenje, Hansa, Samsung (Samsung), Siemens, Ariston and others, as well as the cost of such connection in specialized companies.

Power of the induction hob

As a standard, the power of the induction hob is 7.2 kW. What does it mean? This is the maximum heating stove power consumption. With daily use when heated with two or three burners, the stove will consume less energy. Everything will depend on how quickly you need to heat food after returning home.

How power is transferred to electric current?

one.The installation is single.phase. in the free transformation there will be:

I = 7200 W / 230 B = 31.3 amperes.

2.Three.phase networks are most often used for two phases. Each of the phases supports two heating fields with the same general power. Thus, for each phase, a power of about 3600 watts and current:

I = 3600 W / 230 B = 15.7 amperes.

Even if full power is rarely used, the electric system should be prepared for a situation where all the “burners” will work at the maximum.

How to connect an induction stove. Useful tips

When purchasing a new induction stove, you should not rush to connect it into one of the free sockets. In this case, first of all, it is necessary to determine the possibility of connecting this household electrical appliance to one or another section of the electrical wiring and select the most optimal way to connect it. Consider the question of how to connect an induction stove.

It should be noted that before purchasing an induction stove, it is necessary to clarify which load limit is determined on an apartment (house) and evaluate the possibility of operating a particular induction stove, taking into account its maximum power consumption.

Connection of a desktop induction stove

The desktop induction electric stove, as a rule, has a constructively cord and a plug for connecting to a regular household outlet. That is, in this case, there is no need to purchase an additional cord and fork for connecting an electrical appliance. But in this case, it is very important to choose the right socket to turn on an electric stove.

Very often make an error. include an electric stove in one of the free sockets, without taking into account its load capacity, that is, the load amount that is permissible to include in this outlet.

In the best case, one of the circuit breakers in an electric distribution panel will turn off. As a result of overload on one of the sections of the electrical wiring. But in the absence of proper protection of the electrical wiring, for example, in the case of connecting several wiring lines to one automatic circuit breaker, the overload will lead to damage to the electrical wiring.

Therefore, before starting to operate an electric stove, it is necessary to find out its maximum power consumption and make sure that this electrical appliance can be included in one of the existing sockets. The power consumption is indicated in watts (WT) or in kilowatts (kW) in the passport on the electric stove case, as well as in the technical characteristics in the operating instructions for this household electrical appliance.

It should be remembered that the usual household plug outlet is designed to include household electrical appliances with a nominal power of not more than 3.5 kW, which corresponds to a load current of 16 A. That is, if the power consumption of the electric stove does not exceed this value, then it can be included in this outlet.

Next, make sure that the electrical wiring section that feeds this outlet is able to withstand the load of the induction stove. How to find out?

Firstly, it is necessary to clarify which cable is connected to the outlet, and how it connects to the rest of the home wiring. The cable feeding the outlet must have a section of at least 2.5 kV. mm.

If the cable is connected directly in the home camshaft, then such a fishing line for the trimmer of the wiring withstands the current outlet, to protect such a line of the wiring, you can install the automatic circuit breaker of the required face value. This option is most preferable in terms of reliability.

The second common option is a cable that feeds a socket is connected in a distribution box. In this case, you need to take into account the loads of other sockets connected to this camshaft.

The cable that goes from the main distribution shield to the camshaft should withstand the total load of sockets erected from it. Therefore, if the load of the induction stove is overload for this section of the electrical wiring, then to turn it on, choose another outlet of the corresponding load capacity.

Secondly, it is necessary to evaluate the technical condition of the electrical wiring. If the wiring is in unsatisfactory technical condition, then accordingly, when a new load is turned on, it can be damaged (see. How to audit the wiring in the apartment). In this case, it is necessary to pay attention to the condition of the cable, in particular its isolation.

A cable with copper veins is preferred, but if an old aluminum wiring is mounted in the house, it is highly likely that such a cable does not withstand the permissible load.

It is also necessary to pay attention to the condition of the contact connections of the electrical wiring at the place of connection of the cable in the home distribution shield, outlet, as well as intermediate contact connections in the camshaft.

For inclusion in the network of an induction stove, extension cords and tees should not be used. For the safe operation of the induction stove, it must be grounded, that is, it is included in the outlet with the working grounding.

It is also necessary to pay attention to the condition of the outlet. If the electrical appliance plug does not in contact well with the socket connectors, then such a socket must be replaced.

Connection of the induction hob

The induction hob has great power, it is not included in a regular household outlet, but in a power, designed for a current of more than 16 A.

A power outlet for connecting an induction stove is selected according to its load. The total load of the induction plate can be on average 25-32 A, depending on the quantity and power of the firewood.

In this case, an individual fishing line for a trimmer of electrical wiring should be laid to power the induction stove in this case. The cable section depends on the load of the induction plate: for current 25 A, the copper cable with a section of 4 kV should be laid. mm, for load 32 a. 6 sq. mm.

For safe operation of the induction stove, the electrical wiring must have a working protective grounding. That is, for a single.phase network to connect an induction stove, a three.core cable must be summed up. Respectively, the acquired set of power outlet with a fork should also have a third grounding contact.

If it is not possible to purchase a power outlet of the required power, then as an alternative option, you can connect an induction hob to the terminal block installed in the mounting box. The terminal block should withstand the rated current of the induction stove connected to it.

Job panels connection schemes: selection of stove models

Modern models of plates that integrate into the countertop most often have compatibility with all types of phases. In Russia, there are two strictly defined networks of networks:

Separately, it should be said that in some houses, a 220 V network may have two phases. Before starting work on connecting the hob, it is necessary to study the features of each type of network in order to understand the nuances of work. Each type of system has its own characteristic differences.

Single.phase. Most often, such a network can be found in residential buildings that have been built for a long time. Single.phase networks are divided into two types: two.wire and three.wire. In old.style houses, single.phase systems have a voltage of 220 V.

Scheme Connection of a hob with a terminal

First of all, you need to deal with a two.wire network. It is worth noting that its distinctive feature is the wires of the same color. In this case, the phase is detected by using a probe (screwdriver equipped with an LED) or a special tester.

Three.wire single.phase networks include multi.colored wires. The following shades correspond to a certain electric line:

A single.phase switching scheme is quite common. In rare cases, such a network can have wires of the same color. In such a situation, it is recommended to use the tester, which will more accurately determine the purpose of each wire.

Connection scheme for the hob and oven

A two.phase network, which has a standard voltage of 220 V, is extremely rare. As a rule, such communication can be seen in new buildings. In this case, black color is used to designate the phase (less often. brown). Zero has a familiar blue shade, the earth is determined by a yellow-green wire.

The last connection scheme is three.phase. In such a system, zero and land have standard colors. In turn, the wire corresponding to the phase can be indicated by yellow, red or green color.

Helpful information! On another scale of shades of phase colors can be as follows: white, black or brown.

Choosing a cable and machine guns

As you already understood, a separate fishing line for a trimmer will have to lay from the shield to the hob. Most likely you will lay it secretly, in a box, corrugated roshang or tribe. In this case, only a copper cable is allowed:

  • for a single.phase network with an electrical power of 5.5 kW to 7.7 kW cable with a vein section of 6 mm² (VVG 36 or PVS 36);
  • For a three.phase to a power of 16.4 kW, 52.5 mm² is enough (KUVV 52.5 or KUGV 52.5);

After leaving the meter, it is necessary to install the machine. This requirement is mandatory. There are also recommendations. to protect the equipment and ensure the proper safety, put an RCD (protective shutdown device). Such a ligament allows you to turn off the power not only during overload (the machine operates), but also with problems with insulation (RCD is triggered). RCD is not the cheapest thing, but the hob is incomparably more expensive, so it’s better not to save.

  • For a single.phase network, we take an automatic machine for 32 A, an RCD of 40 A with a differential shutdown current of 30 mA.
  • for three.phase. automatic 16 A and RCD for 25 A with differential shutdown of 30 mA.

How to connect a gas panel?

First, it is worth directing attention to how the panel is attached. Install it in the countertop, then align and fix it. To do this, at the bottom of the model, special brackets are provided and include the electric wire in the outlet.

Paronite gaskets should be put in nuts. Then, open the gas and turn on the burners in order to check the strength of the connection and eliminate the possible gas leaks. For ease of checking, use a gas analyzer.

Installation procedure

  • Take short stupid screws and screw 4 springs into the holes that are located on the sides of the device;
  • We insert the hob into the kitchen module, level it and slightly press it to the center. this will provide the maximum even possible installation;
  • If it has side profiles, then after you insert it into the kitchen module, you need to insert 4 fasteners. Pay attention to the fact that the screws of the central springs remain affordable.

Before connecting an electrician, you need to check:

  • The condition of the outlet: it must be grounded and comply with all technical standards and standards;
  • corresponds to the lyrosetis of the required voltage when connecting;
  • whether the socket of the plug corresponds.

Installation of the hob

Remember that installing the hob in the countertop with your own hands or installing the panel above the oven, requires the maximum care of you. You must certainly take into account a large number of requirements that will help you competently, quickly and efficiently install it. Guided by the above instructions, you will not need to attract specialists to conduct this operation.

Before the connection is made, it is worth carefully checking the voltage and current frequency in the outlet and compliance with all the established standards for the safe independent installation of the panel.

Sealing and sealing

To prevent moisture access and deformation of the material of the countertop, the holes are treated with sealant and compacted. The use of silicone sealant has several nuances:

  • The surface must be prepared. wiped from pollution, dust and treated with a degreaser;
  • Glue the mounting tape on the sides of the seams with an indent equal to the mowing fishing line;
  • Cut the nose from the tube and put on it a barrel in the form of a syringe;
  • Charge a tube into a gun and press a lever to reduce pressure;
  • Gradually squeeze the sealant, spraying the seam with a solution of soap and water;
  • Close the seams with a spatula and remove tape.

The laying of the seaming of the seam will prevent moisture access to the countertop and temperature difference. Use a special aluminum tape, which is glued to a low.fat and dried surface, slightly pressing.

Before the sticker, it is important to check the correspondence of the thickness of the seal and the inner depth of the sides of the panel. If the tape is thin, then the gap is formed through which moisture will flow. The whole strip is laid along the perimeter of the cut out from the front of the cabinet. Ideally, the seal should be 1 Washing Machine below the side.

Advice! A plastic tape for drywall 30 mm wide is suitable for sealing.

Connecting the device to a three.phase network 380 V

To install the device, a cable with five cores is used, in which there are such parameters: 3 phases, protective grounding and “zero”.

The induction stove should be installed in the following sequence:

  • We connect the 1st phase wire (black, white or brown) to the terminal under the number “1”, under the second number-the following, to “3” terminal-the remaining one.
  • The jumper is connected by terminals under the numbers “4” and “5”, and to them. a zero wire (usually blue).
  • To the terminal “grounding” marking PE connect a yellow-green wire.

note! The procedure for connecting the phase to the contacts of the device is not so significant, that is, there is no difference what color the wire will connect the first.

The choice of power cable

When choosing a cable necessary for connecting an induction stove to a power supply network, you need to remember that according to the current SP31-110-2003 “Code of Rules for Design and Construction. Design and installation of electrical installations of residential and public buildings ”, to connect electric stoves in residential buildings, it is necessary to use three.core copper cables with a cross.section of at least 6 mm 2. For this purpose, a domestic cable of the VVGNG-LS type or its foreign analogue of NYM is best suited.

If the connecting cable is not included in the set of the induction panel, then it must be selected based on the power that the latter consumes. The recommended section of the cores of the VVGGN-LS type connecting cable is given in the table below:

The power of the induction panel, kW The diameter of the copper core of the cable VVGGNG-LS, mm The operation current of the automatic load switch, and
up to 3.5 2.5 sixteen
from 3.5 to 5.5 4.0 25
from 5.5 to 7.2 6.0 32
from 7.2 to 8.8 10.0 40

Advice! When choosing a cable for connecting to an electrical power panel with induction, you need to focus on the type of power outlet. Depending on the number of contacts in it, a cable with the corresponding number of cores is also bought.

After choosing and buying the required cable, it must be equipped with a network fork and connect to the induction panel. In this case, the length of the cord should exclude both its strong tension and excessive sagging. But first, a separate fishing line should be carried out for the trimmer and install the appropriate outlet or connect the plate in another way.

For more operational repair in conditions of inaccurate determination of a malfunction (and not only), you can give several useful tips. Firstly, the generators on the burners are made in the form of an independent module. They are removed. Changing the generators in places (from one burner to another), you can quickly understand what has broken, the coil or its high.frequency voltage blog.

The second advice will sometimes save a lot to save on repair. For non-cheap or rarely found due to non-proliferation in the plates market, a burned part can be unique and very expensive. And its rarity raises the cost of replacement even more. But install an element indicated on the scheme of the plate, is not at all necessary. There is a database of compliance of electronic components. It can be easily found on the Internet at the request of Datasheet or on thematic forums. It will be found more inexpensive or accessible on sale an analogue of the part, which is needed to replace in an induction stove.

If the cause of the breakdown has not been established, or there are difficulties about how to purchase and install failed modules, then it is better to contact professionals for the repair of an induction stove. You should also remember the warranty service, the right to which you can lose when opening the unit independently. The induction stove is a “smart” technique and requires careful compliance with the operating rules.
