Which outlet to put on the hob

Rosette for the hob: what is needed, tips for choosing a socket and cable

Modern cuisine is equipped with electrical engineer than starships in old films. And requires a responsible approach to the choice and installation of wiring and electrical products.

Let’s start with the fact that you decided to please the hostess of the kitchen and install a lot of modern household appliances, both small and large. First deal with a new electrical wiring. To get started, divide the lighting and power circuit, and then calculate the number of equipment and how much will “eat” kitchen units. Most likely, the supply contours will need several. In order not to hang formids for home.Made rules in the style of “washing and dishwasher at the same time do not include!””.

Remember. All powerful kitchen appliances should have a separate fishing line for a power trimmer from an electrical panel.

But if the washing machine can be moved to the bathroom, and the dishwashers can not have everyone, then the stove and the oven will not go anywhere from the kitchen. We’ll talk about them, or rather about sockets for the hob and ovens.

Installation of the hob

Marking is perhaps the most important stage of work associated with the installation of a hob with your own hands, on which, oddly enough, most of the nuances. Judge for yourself. From how clearly and accurately you can mark, and then cut the hole for the hob, the entire appearance of the kitchen depends.

This is just the case in which an error in one centimeter may be irreparable. You always need to remember the cost of a canteen. Buying a new one is not so cheap. The fact is that the hob itself should fit clearly above the cabinet, and there is practically no stock in width there.

You can marry the landing hole in two ways. It can simply be laid on the countertop, focused on the eye and circle with a pencil, or go through professionals and calculate everything up to a millimeter.

Naturally, it is better to choose the second option for solving the issue, since in this case the chances of mistakes at least. This is done as follows.

To begin with, the internal boundaries of the cabinet are transferred to the countertop, above which the hob is installed. In fact, you will have to draw two parallel lines, which, together with the front and rear edge of the countertop, form a rectangle.

Then, after a diagonal, you need to find the center of this rectangle and build a coordinate system relative to it. Draw a cross, one fishing line for which is parallel to the front edge of the countertop, and the other is perpendicular.

After that, on the resulting coordinate system, you need to postpone the dimensions of the crafted part of the hob. They will have to measure. You need to take into account a small supply so that the panel can be re.Center during installation.

After the dimensions are postponed, we draw four lines (two parallel to the edge of the countertops and two perpendicular) through the obtained points and we get an even rectangular figure, which after cutting will turn into a landing hole for the hob.

You can cut the landing hole for the hob using three different electrical tools. This is a jigsaw, drill or manual milling machine.

The most accurate and beautiful cut is obtained when using a hand cutter, but you can even not even ask about the presence of it in the home workshop of a person not related to construction.

Not everyone also has a jigsaw, but at least it is not very expensive, and for carrying out these works it can be bought. Well, the drill has almost every household man.

It is quite difficult to seal torn edges, and this must be done, and problems will arise in this regard. In principle, they are solved, but more on that later.

Cut the hole with a drill. I’ll just tell you the principle-with the help of a drill and a drill with a diameter of 8-10mm along the perimeter of the hole, with the smallest step, the mass of holes is inhabited, which, using the same drill, are subsequently combined into one single slot.

There is only one nuance here. You need to drill from the inside of the marked rectangle. And one more thing-so that a piece of cut countertop does not damage the furniture, you need to put anything under it-for example, put a stool in the cabinet and put the scrap stove on it.

It is much easier to cut a hole with a jigsaw, but the thing is that it is also difficult to do without a drill. You will need to drill one single hole for a file.

In principle, with a strong desire, this hole can be shifted manually. In addition, you can crash into the countertop itself, though a certain dexterity will be needed for this. Again, do not forget about precautions. The stand under the cut part of the working surface will not be completely superfluous.

After the hole is ready, it is necessary to water its waterproofing. When water enters or even moisture in the end of the countertop there is a very high probability that the material from which it is made will swell, and the countertop will deteriorate.

As a rule, the end of the cutting end is treated with silicone. If you cut out a hole with a drill, then it will be difficult to do this qualitatively. You will have to tinker.

Hobs Power

The power of the hob is an important parameter for choosing a device for three main reasons:

  • The speed with which your dishes undergo heat treatment depends on the power. Agree that it is better when it is possible to cook dishes as quickly as possible.
  • Modern plates have burners of different capacities, and it is very convenient. If you need only a small amount of heat, why spend excess gas or electricity on useless warming up in the kitchen.
  • However, the reverse side of the question should also be taken into account. The power of the largest burner should also be sufficient to quickly cook a large pan of soup.
  • In modern kitchens, air conditioners are often installed. When the thermal energy is released in too large quantities, the load increases accordingly to the air conditioner. At the same time, unnecessary expenses for air heating and its cooling are completely not justified.

So, it is worth picking up a hob with such power that the cooking time is fast, but released by heat. Optimal.

Electric hobs power. The electrical device of the traditional design consumes the highest electrical power from all types in question, so we will start the review from this option.

The most widespread market in our time were plates with four burners. Thus, the standard number of heating points over the decades of the existence of home plates has not changed. The connection is also similar. However, manufacturers went to modernize the heating sites, so they have different power:

which, outlet
  • The first burner has the smallest power-0.4-1 kW;
  • Two burners have an average power. About 1.5 kW;
  • The fourth burner has the greatest power. Up to 3 kW.

Thus, the total energy consumption reaches 7 kW. However, there are electric surfaces with additional properties, including:

Project requirements

If the wiring on which the installation of the outlet for the oven is not met by the following requirements, then it must be changed, and it is desirable to clarify this issue before the purchase of the device:

    Separate fishing line for trimmer. Standard wire and outlet are designed for a nominal current in 16 amperes. The voltage on the network is always 220 volts, so you can calculate the maximum power of the outlet for an electric stove, which will turn out to connect through it. The power is equal to the product of the current force on the voltage. 16 multiply by 220 is 3520 watts or 3.52 kW. This means that if a socket for purchased hob and oven is connected to a common kitchen circuit, then these devices can only be used alternately, and turning off everything else. A microwave, a kettle, etc. If you connect an oven to one outlet, and to the other, on the same line, for example, a hob or another rather powerful device, then the wiring will bask and soon will fail if it does not immediately close.

  • The cross.Section of the wire. In a closed.Type wiring, a copper cable with a section of 2.5 mm² withstands the connection of devices power up to 4.6 kW. If the device is more powerful, then the wire must be selected according to the following table:

According to these data, you can calculate not only the entire wire in the kitchen, but also which outlet is needed for the connected hob. It is clear that if the cross.Section of the wire is selected, then in one outlet, even double, it will not be possible to include more than one device, therefore, in case of such necessity, the wiring in the kitchen should be selected with a margin.

Choosing a place to locate a socket

If the choice fell on the connection of the oven and the hob to the outlet, then an important question arises: where to place it? Naturally, to arrange sockets above the working surface is not aesthetically aesthetically pleasing, so you need to find a place for a hidden installation with good access to turn on/disable the device.

Device manufacturers recommend not to have sockets behind the connected electrical appliances. The best choice of location is the lower part of the wall at the level of the basement of the kitchen set under the device or on the wall with access from the neighboring cabinet.

Selection of sockets and forks for the hob

Hobs on average consume 7-8 kW. This indicator corresponds to the current 32-38a. At the same time, ordinary sockets and forks for household electrical appliances are designed for current 16A-25A. Therefore, to connect electric stoves and ovens, special power outlets and forks for hobs that support large cables (4-6 mm²) are used.

There are several types of components on sale that meet such requirements. To connect the hobs, the RSh/VSh.32 connector is most often used. There are two types of such sockets and forks: for connecting to a single.Phase network and for connecting to a three.Phase network.

Attention! A socket for connecting a hob is selected based on the characteristics of a particular model. Panel power is from 3.5 to 10 kW. The higher the energy consumption, the more serious requirements are imposed on components and electrical wiring.

Thus, having bought a new plate, it is not connected to the first outlet that falls. For uninterrupted and safe operation of the device, special components are needed.

For induction hob

The average load of the induction plate is 25-32 A depending on the quantity and power of the fireplace. Therefore, to connect the device, a power outlet with a selected electrical wiring line is used. The cross section of the cable used depends on the load of the device: for current 25 A, a copper cable with a section of 4 kV is used. Mm, for load 32 a. 6 kV. Mm.

Important! For safe operation of the hob, wiring with protective ground is required. This means that for a single.Phase network a three.Core cable is connected, and the power outlet with a fork used has a third grounding contact.

For desktop induction stove

The desktop induction electric stove is a low.Power device with a cord and a plug fork for connecting to a regular household outlet, you do not need to install a special power. But first it is worth evaluating the condition of the socket and electrical wiring. If the electrical appliance plug does not contact well with the connectors, such a socket is changed. It is also necessary to make sure that the wiring is serviceable, and the connected cable has a section of at least 2.5 kV. Mm.

For a gas hob

Connection to the electrical network of a gas hob is required if the device is equipped with an electric clock function. In this case, a separate outlet is installed on 16 A with grounding, connected to an automatic circuit breaker on the shield.

The socket is installed on the wall under the countertop. If the cabinet under the stove is a deaf wall, a hole is cut out in it for free access to equipment.

Description and characteristics

When the old wiring is checked or new is laid, they begin to install sockets. Let us dwell in more detail on the characteristics of sockets and forks for hobs and ovens.


Kitchen appliances with a capacity of more than 3.5 kW are connected to electricity through special power outlets (the power of the equipment is indicated in the technical documentation). Manufacturers produce several varieties of such outlets, but their main difference from ordinary household ones is the ability to work with high.Power currents.

Electric slabs and oven cabinets are made using external metal parts, which, when broken by electricity on the housing, are energized. To protect the user from current damage, grounding is used.

Attention! Oven and hobs are connected through grounding. There are 3 or 5 contacts in the outlet or fork for such technology (in the first case, for the 220 volts network, in the second. For 380 volts).

Distinguish single.Phase power outlets and three.Phase. The former leads to the device phase, working zero and grounding wire. The latter are designed for 5 contacts and withstand current strength of at least 32 A.

By the method of installation, components are distinguished by 3 types: hidden, overhead and combined:

which, outlet

INSTALLING ELECTRIC COOKTOP. DIY Range or Stove Top Installation Instructions.

  • Hidden. With a hidden installation, the socket is mounted in the wall. This hides the working surface of the outlet, which increases the safety of its use, reduces the risk of moisture and dirt.
  • Invoice. Complexes of this type are mounted on top of the discharge. As a result, the outlet sticks out above the surface of the wall, is not protected from moisture, dust and fat.
  • Combined. This type is a hidden outlet additionally protected from external factors with a lid.

In design, power outlets are single and double. Double is convenient in that if necessary, they connect additional kitchen appliances (mixer, microwave, hood, etc. D.).

Sockets differ in the magnitude of the current force on which they are designed. There are products for 25 A, 32 A, 63 A and 125 A. Power is selected in accordance with the consumption of equipment capacity.


A special power fork is selected for a power outlet. In its inner part there are 6 contacts that are used to connect the wire. Terminals for numbers 1, 2 and 3 are designed for phase conductor (l). They are connected by a jumper. Nol (n) connect to terminals 4 and 5. Terminal 6 is required for grounding.

Types of forks

The average power consumption of electric plates and hobs is 7-8 kW, which corresponds to current 32–38 A. For this reason, the standard fork for connecting other electrical appliances is not suitable here, it is designed for current 16–25 a. In addition, the power fork for connecting the plate supports cables and large cross.Sectional wires. 4-6 mm².

There are several varieties of household outlets and forks that meet these requirements. To connect an electric stove and hob, use the RSh/VSh.32A connector. Such a ligament is made both for connecting to a single-phase network of 220V, and for the use of two- and three-phase networks.

Important! Often, manufacturers of electric slabs supply devices complete with a suitable fork and appropriate outlet. In this case, a set from the kit is used to connect, as it happens that the power fork of one manufacturer does not fit the outlet of another.

If there is no plugs and outlets in the kit, they are bought on their own. To understand which fork at the hob, study the instructions for the device and consult with electricians serving your house.

There are forks for electric stoves of two colors on sale: black (from carbolic) and white (from plastic). White, as a rule, better and characterize increased wear resistance, but they are more expensive. In design, both types do not differ from each other and are connected the same.

Which socket to choose

A rosette for a hob and/or oven is selected depending on the characteristics of the device. Hobs and ovens are both single.Phase and three.Phase, have a power from 3.5 to 10 kW.

There are hidden, overhead and combined sockets for plates:

  • Hidden installation involves the installation of a socket in a recess in the wall. Thus, the working surface of the drive is closed and protected from moisture.
  • Follow sockets are installed over the bends. In this case, the structure sticks out above the surface of the wall and is not protected from moisture and dirt.
  • Combined sockets are the same hidden, but additionally protected by a special lid. In this case, the contacts are closed from the effects of any external factors.

The first and third species are suitable for walls made of concrete and brick, the second for wooden walls.

Hob fork

To supply electricity to the hob, use a three.Core cable made of copper. If you need 380 volts, you need a cable with five veins. The cable section is selected based on the existing load and according to the calculations of the working current. However, the section should not be less than 4 square millimeters. The machine is taken for 32 amperes, and if a 6 mm cable is used, the machine should be 40 ampere.

The peculiarity of the hob in the extremely rapid heating. This circumstance is caused by the high power of the device, which can reach 7 kilowatts.

  • Buy a 220 volt power fork (alternating voltage).
  • Remove the protective panel. In the inside of the fork there are 6 contacts that are used to connect.
  • Terminals for numbers 1, 2 and 3 are used to join the phase conductor (L). These terminals are connected by a jumper.
  • Contacts numbered by four and five are used to connect zero (n).
  • The terminal under the sixth number is designed for grounding.

Note! If the phase conductor is connected incorrectly, a protective (RCD) or a differential machine will work.

Connection of the oven to the mains

To choose the right cable, outlet, as well as a fork for connecting the oven, if it is not in the kit, you need to determine the power of the plate. To do this, we turn to the technical passport of the electrical appliance, which will indicate the nominal power and the diagram of the connection of the oven will be indicated.

Many people wonder what cable is needed to connect the oven, “the power of which does not exceed 3.5 kW. To solve this problem, a flat three-core cable with a section of 2.5 mm2, for example, the VVG-P-P 3×2.5-0.66 production cable, production of Caucasabababol JSC, complies with the requirements of GOST 31996-2012.

    The cable of this plant has a color marking of the veins: white, blue and yellow-green (railway. In addition, to connect an electric oven to the mains, they will also be needed:

  • Footage (mounting box);
  • A socket for connecting an oven on a current 16a with a grounding contact type Schuko (German standard);
  • Fork (if it is not complete with an oven).

To provide additional protection against electric shock, connection in electrical panel is recommended to be carried out through a differential device (RCD, differential machine).

It is recommended to provide such a device in advance in the shield or install in it. If it is also supposed to install an electric hob, then the oven and the hob can be connected from one difavtomat selected according to the general load.

Before laying a cable, it is necessary to carry out construction work in order to prepare the walls for the installation of a cable and sockets. Preparatory work for connecting the oven is carried out in the same way as described in our previous article “Connection of the hob”.

In the fine, we lay and fasten the power cable of VVG-P 3×2.5 to the proposed location of the outlet, to which the electric oven will be connected. In this case, the end of the cable in the mounting box should have a margin of length for repeated connection.

It should be noted that the choice of the location of the outlet should be performed at a height convenient for operation (up to 0.9 meters from the floor level), but it should not be behind the oven. It is best to install a socket on the right or left side of the oven.

    After laying and fixing the cable, we produce in the shield its connection to the protective apparatus in the following sequence:

  • The cable core, which has a white color marking, is connected to the lower terminal of the differential circuit breaker with the “2” engraving;
  • Cable veins with color marking. To the lower terminal with the engraving “N” of the differential circuit breaker;
  • Yellow-green cable core-to any screw terminal tire tire.
    After we perform finishing work and install and install electrophurnier. In the mounting box, we clean the cable and connect the outlet:

  • We connect the veins of the VVG-P 3×2.5 cable with isolation of white and blue colors to the extreme sockets of the outlet. If the sockets of sockets have labeling “L” and “N”, then in this case we connect a white vein to the terminal with the marking “L”, and blue to “N”;
  • Cable cable with yellow-green coloring-to the central terminal that has a marking or re.

If there is no plug in the kit with the oven, then you must connect it. To do this, a pre.Purchased fork, designed for current 16 A, disassemble and pass the cleaned and appressed wire of the oven through a special hole in the case.

    We carry out the connection:

  • Veins with insulation of brown (black or other.) and blue. To the extreme bolted connectors of the fork;
  • Vein with isolation of yellow-green color-to the central bolt connection of the fork with the marking of grounding.

After that, fix the wire and collect the fork. Now you can check the performance by completing the connection of the electric oven to the outlet and connecting the power in the electric shield (you need to take the difavtomat lever).

If everything functions normally, you can perform the installation of an oven in a specially prepared niche.

Oven power kW

The power consumption of the oven can be different. From 1 to 4 kW. Models that matter in the range from 2 to 3 kW are the most common devices and are simple devices for household use.

If models are used, the power consumption of which is more than 3.5 kW, then you should equip a separate outlet that can withstand a large current force. This is necessary to ensure the normal operation of the electric network.

Most of the Bosch built.In ovens has certain parameters. The height usually ranges from 55 to 60 cm, the devices from 40 to 45 cm high are less common.

Such electrical devices have a convenient control panel on which data on the preparation process and other information about the work are displayed. The presence of additional functions affects the power of the oven in the KW, so this parameter should also pay attention to.

    Such electrical devices in terms of energy consumption are divided into several classes. There are 7 classes that have the following energy consumption indicators (kW/h):

  • Less than 0.6;
  • 0.6-0.8;
  • 0.8-1;
  • 1-1.2;
  • 1.2-1.4;
  • 1.4-1.6;
  • More than 1.6.

All these indicators belong to the built.In oven cabrics of small volume. If we talk about devices that have large sizes, it is worth noting that such devices related to class A will be consumed from 1 kW/h.
