What kind of outlet is needed for the oven?

Selecting and installing an oven and hob socket

The hob, built-in type is connected to a separate line with a socket capable of withstanding a current of 32 to 40 A and ensure reliable earthing. The supply cable contains three copper wires with a minimum cross section of 4 mm². Modern electrical wiring in an apartment also allows you to make a connection to a four-wire power cable.

Outlets for panel connections come in two types:

If you connect the hob yourself with the plug on the end of the cable, this is no problem. But to connect the hob cable to the mains, where there is no plug at the end, you already need some knowledge.

For example, a cable with four conductors comes from the panel, while only three power wires come out of the wall. This means that the panel needs a connection from two phases, but in the apartment only one.

kind, outlet, needed, oven

In this case the technology is as follows: the brown and black wire from the cable from the cooker hob twisted together and connected to the phase wire, the power line that comes out of the wall. Connect the blue wire of the cable (neutral) to the neutral wire of the power supply. The yellow-green protective ground wire remains, it is connected to the same ground wire in the power line.

In the event that the wires come off the wall the same color, using a multimeter to find out which is the zero and which is the phase, and determine the integrity of the grounding conductor. The resulting connection of wires should be insulated.

Before connecting the hob, which already has a plug on the cable, be sure to check that the power wires and contacts inside the socket match. Sometimes they can be different. To do this, the socket is disassembled, and using a multimeter to determine the correspondence of the connection, if necessary, the wires are swapped.

  • Connecting an electric cooktop involves the installation of a separate circuit breaker and RCD, these devices are selected with the following calculation: for the socket at 16A circuit breaker is needed at a current of 25A, and the RCD from 40A. It is unacceptable to use the power line of the panel to connect multiple power devices at the same time.
  • The body of the hob must be earthed, not to the body or wire from another appliance, but to the outlet terminal, a separate wire from the hob.
  • Most manufacturers already sell appliances that are equipped with a protective grounding bar, it just needs to be connected to the grounding wire in the apartment.

What receptacles are required?

The socket-outlet selection is usually based on the design of the plug on the oven power cord. This is the right approach because manufacturers always equip their products with parts suitable for the operating loads plus some safety margin.

The type of socket depends on the power of the oven. If it does not exceed 3.5 kW, you can use a standard model with a grounding electrode (type E or F), the same as for kettles or microwaves. In this case, it is necessary to ensure compliance with several conditions:

If the capacity of the oven exceeds 3.5 kW, the same requirements must be met, but with some modifications:

If the oven is not equipped with a power cable (some models are not equipped with a cable, there is only a panel to connect the wires), the best option is to buy and install a more powerful socket. In this case, having extra power does not harm or impair the oven‘s operation.

Sometimes the problem with sockets is solved drastically. cut off the existing plug and attach another, suitable. This solves the issue, but cancels the warranty contract. It is necessary to keep this in mind so as not to get into an unpleasant situation.

Distinguishing features

Regardless of whether you install an outlet for the cooker hob or the oven, it is the power socket that must be installed for them. They are quite a few varieties. each manufacturer can make a design on its own, while respecting the requirements of GOST or PUE. Its main difference from the household is the ability to handle high-power currents, which is reflected in the thickness of the conductive contacts.

The vast majority of electric stoves, hobs and ovens have external metal parts that, under unfavorable circumstances can be live. To protect people and equipment from electric shock in such cases, grounding is applied, the contacts of which in conventional sockets have the form of clamping tendrils. The oven outlet cannot be equipped with this protection because it is insufficient for high amperage currents. As a result, the socket grounding contact is made on the plug itself by a separate pin. Some people confuse a three-pronged plug with a three-phase plug, but it is really a phase, zero, and ground.

Types of power outlets

Modern power outlets designed for electric stoves differ in several ways. Voltage rating of the outlet from 380 V. for single-phase mains. there are several connector options, how to connect an outlet for an electric stove with multiple phases:

With 3 pins. ground, phase, zero;

With 4 pins. 3 phases, neutral;

with 5 pins. ground, 3 phases, zero.

Their contacts can be needle or knife-type.

Installation method

There are several types of devices based on this characteristic:

Open installation of an outlet under an electric stove is optimal for loggias or rooms with high humidity. Mounted on the wall with exposed electrical wiring or by using an adapter adapter of the electric stove.

Hidden, or internal socket for electric stove, used in buildings for private use, for example, with a single-phase network of 220 volts for electric stove 32A. Installed in a special recess, the sockets, and the wires are hidden in the grooves.

Resistance to external factors

Connectors for electric stove and their degree of protection differ, the most common of these indicators is IP44, where the first number. the index of resistance to dust, and the second. moisture. When connecting the socket, the index for dust is used from 0 to 6, and for moisture from 0 to 8.

Range Receptacle Wiring

Variety and purpose

This criterion provides the following indicators:

  • The simplest kinds of sockets for the electric stove without grounding;
  • connectors with grounding;
  • Connectors with safety shutters;
  • Connectors with ejectors or timers;
  • with RCD for areas with a high degree of danger.
  • In addition, sockets for stoves can be single or double.

Important: according to the recommendations of experts, the use of double is more effective. they have more power than the equipment needs, in addition, such a socket can be additionally used for another piece of equipment in the kitchen.

Operating time

The operating time of the power socket for 32A stove with 220V is counted by the number of switching on and off moments. Products of high quality can provide such cycles up to 100 times.

The period of use of the socket under the kitchen electric stove is determined by the variant of clamps in the spring mechanism with contact paws. quick-clamp or double-clamp, each variant is good in its own way, but the first one is installed instantly.

Socket Selection Factors

When selecting the socket 220V for electric stove 40A, it is necessary to take into account that a fork diameter of 4 mm is suitable for it, which is the standard in the territory and other countries of the former CIS, while the stove from Europe will have slightly different parameter of the fork diameter, which is 4.8 mm and is the European standard. It is also important to consider the distance of the contacts from each other, which can have a difference.

Choice of receptacles

Warning! It is strongly advised to use a separate socket for each kind of appliance.

First of all, you should carefully familiarize yourself with all the technical characteristics of the electrical appliance you have purchased and only on the basis of the available information proceed to select the socket.

The main parameters here will be:

  • Single-phase or three-phase. Depending on mains voltage. For household appliances are suitable single-phase socket (mains voltage 220V), and for industrial use. three-phase (if the voltage is 380V).
  • Nominal load. Choose according to the value of the load of a particular appliance. Should be selected with a reserve, if the load of the cooker hob 10A, then the selected socket should be rated at 16A.
  • Outdoor or indoor. The types of installation are discussed in more detail below.
  • Enclosure protection level. Since the socket will be in the kitchen, you should opt for a more protective housing. A system of symbols, which can be seen in the technical documentation, as well as directly on the body of the socket, will help you. It looks like this: IP XY. Where X shows the level of protection against the impact of foreign objects (indicated by a number from 0 to 6). the higher the value. the higher the level of protection. The Y value indicates the degree of protection against moisture. As the kitchen is a very humid environment, it needs to be at least IP rated
  • Earthing. A grounded socket is essential for safe use of the oven and hob (as well as all other appliances).
  • Visual characteristics. Yes, this is a very subjective selection parameter, but if you can visually see that the socket is not of high quality (cheap plastic, unreliable contacts, etc.), it is a good choice.д.), it is worth to refuse to buy it in favor of a more reliable model, even if it will cost more.

Features of the device socket for a powerful electric stove

The socket for connecting a high-power electric stove is easy enough to distinguish by appearance. On the case should not be petal grounding contact, as in the lauded euro socket.

The number of pins must match the type of power supply. for a single-phase network on the plug and socket will be four contacts, and for three-phase. five. Grounding the electric stove is done separately.

When the electric stove is in operation, the current consumption can reach 10-30 A, so the socket should not just be a certain number of contacts, it is not enough. It is desirable that the plugs fit equally snugly on the terminal pairs of the outlet.

An ordinary outlet for a vacuum cleaner, air conditioner, or even a small electric stove or iron, experienced craftsmen select from several options according to the following characteristics:

  • The plug goes into the terminal sockets of the socket with little effort;
  • Once the plug is inserted into the socket, there must not be even the slightest play in the connector;
  • The plug pins are installed in the housing on special heat-resistant bushings.

This is not enough for high-powered electric stoves. Firstly, craftsmen recommend that you choose sockets and plugs with flat pins, it is this device pins provides a uniform contact on all terminals. Secondly, you should avoid designs where the terminal pairs are made of steel and have a galvanized coating. At high temperatures, the zinc begins to burn out, and if the plug pins are made of brass, then under a full load of electric stove pins are simply welded to the terminals of the socket.

Selecting Socket and Plug for the Hob

Cooking hobs draw an average of 7-8 kW. This value corresponds to a current of 32-38A. At the same time, conventional sockets and plugs for household appliances are designed for a current of 16A-25A. Therefore, to connect the electric stoves and ovens use special power outlets and plugs for stoves, supporting a large cross section of cables (4-6 mm ²).

There are several types of accessories available that meet these requirements. To connect the hobs, the most commonly used connector is a MSh/BSh-32 socket. These sockets and plugs come in two kinds: for connection to a single-phase network and for connection to a three-phase network.

Warning! The socket for connecting the hob is selected according to the characteristics of a particular model. The power of the hobs comes in the range from 3.5 to 10 kW. The higher the energy consumption, the greater the demands on the accessories and electrical installation.

So when you buy a new stove hob, you don’t plug it into the first available socket. For trouble-free and safe operation of the device you need special accessories.

For an induction cooktop

The average load of an induction stove is 25-32 A, depending on the number and power of burners. Therefore, to connect the appliance, use a power socket with a dedicated wiring line. The cross-section of the cable to be used depends on the load of the appliance: for a 25A current rating, a copper cable with a cross-section of 4mm² is used. For a 25A load, a copper cable with a cross-section of 4Km² is used, for a 32A load. 6Km². mm cross-section.

Important! Electrical wiring with a protective earthing connection is essential for safe use of the hob. This means that for a single-phase network is brought three-core cable, and the power socket kit used with a plug has a third grounding contact.

For an induction hob

Table-top induction stove. low-power device that has a cord and plug to connect to a regular household socket, install a special power socket is not necessary. But first it is worth assessing the condition of the socket and the electrical wiring. If the plug of an electric appliance doesn’t make good contact with the sockets, the socket must be replaced. You must also make sure that the electric wiring is in good order and that the connected cable has a cross section of at least 2.5 kV. mm.

For a gas hob

Connecting the gas cooker hob to the mains is required if the device is equipped with an electric ignition function. In this case, install a separate socket at 16 A with grounding, connected to the circuit breaker on the switchboard.

The sub-socket is installed on the wall under the countertop. If the cabinet under the stove has a blank wall, cut a hole in it for easy access to the equipment.

How to install an oven socket outlet

Before you begin installing the socket, you should first read the information on the appliance data sheet. The data sheet contains information on the electrical equipment dimensions and connection conditions.

Prohibited installation locations

Socket outlets are strictly prohibited in some areas. They are presented:

Important! If the socket is installed under a sink, it must be protected from moisture.

Recommended installation locations

Always keep in mind that the socket must be installed below the worktop. The best way to place it is to use a box.

important! You should always consider the space available near the socket, because it must be freely accessible. This point is very important for safety, because even a properly installed socket can break or catch fire. In case of danger, quick disconnection of the device from the power grid is required.

The socket outlet for the oven can be installed close to the hood duct or on the working wall of the kitchen set.
