Connection of the oven to the mains
Today, more and more often use electric shock cabinets. Accordingly, a number of questions immediately appear on how to properly connect the oven to the mains. This article is devoted to how and with the help of which to bring power to the outlet and connect the oven to the mains.
For electrical and construction work, we will need the following tools:
Voltage indication device. For these purposes, it is best to use a multimeter; construction (mounting) knife, pliers or a special tool for pruning cable/veins and cleaning insulation; cross.Shaped/flat screwdriver or electric screwdriver with a set of bit; Tools for making holes for installing an mounting box and preparing a fine.
First of all, we want to remind you that the connection of ovens and the production of electrical and construction work should only be carried out with full compliance with safety requirements. Before starting installation work, it is necessary to turn off the power in distribution. To do this, lower the difavtomat lever, and then use the multimeter to check for the presence of power. If the value on the dial of the device has not changed, then you can start mounting operations.
So, a socket under the oven is definitely needed when you purchased an independent oven. Such devices have their own electric wire for connecting with a plug fork at the end.
If you purchase an oven with a wire and without a plug fork, then most likely it is a dependent oven and it was complete with a hob panel. However, do not be scared. It can also be connected to a socket, but for this you need to install a plug on the cable. Most likely there will be three wires in the cable of such an oven, so you need a fork with grounding contact for 16 amperes.
Installation of the oven of the built.In
Connection of the oven begins with the preparation of the niche for its location. It is necessary that there are no distortions (we use the level to control this moment), otherwise the device may quickly break due to the improper distribution of heat.
Before installing the oven with your own hands, you need to prepare a place for work in advance. First of all, a niche where it will be installed. It is important to make sure that there are not the slightest distortions here. To do this, use the level.
If you allow at least a slight skew, the device can fail after a few years of operation. Heat will be distributed incorrectly and unevenly, which will damage thin electronics.
When the built.In oven works, a large amount of heat is released. Its accumulation can lead to a variety of problems. The product itself may fail from overheating.
Even worse, if a wooden cabinet shuts up, and then lights up. This will lead to a real fire. Therefore, in order to install such a technique on your own, you need to carefully calculate every step.
The risk of overheating and fire will be zero if you properly place the closet in the niche before connecting it to the network.
Experts set such a distance from its walls to the edges of the niche:
With this distance, high.Quality ventilation is provided, completely eliminating the risk of technology overheating.
Features of the installation
Electrical equipment is much simpler, and therefore it is preferable to install with your own hands. However, it is also important here to properly install, since a short circuit can become as fatal as a gas leak.
As a rule, manufacturers of kitchen sets and built.In equipment adhere to uniform standards, so there should be no problems. But checking the roulette correspondence of the size before connecting the oven will be useful.
Connecting an electric oven is much easier than a gas. Therefore, many people decide to perform this work on their own without overpaying to specialists.
Yes, there are no hoses along which gas is coming, but still you can’t relax, forgetting about the elementary rules of electrical safety. After all, one mistake is enough for a short circuit that may well lead to a fire.
First of all, you need to seriously approach the network cabinet. The electric oven is a very powerful household appliance. Therefore, to connect it, it is necessary to use a separate branch of the wire.
Over, its section should be at least 2.5 squares. Throughout the wire should not be twisted (even very high-quality connected) and any other damage. Otherwise, the danger of short circuit increases sharply.
A branch intended to ensure the energy supply of the oven, it is necessary to equip the circuit breaker. The power is calculated for a specific model, depending on the strength of the current consumed during the operation of the oven.
In most cases, this number lies in the range from 16 to 20 amperes. In cases where the electrical hob is connected together with the oven, you should choose the machine, taking into account the total power consumption.
Grounding is an obligatory attribute of a modern oven cabinet. Only it allows you to ensure complete safety of working with an electric oven. If we are talking about a private house, then there are no problems here. In apartments, especially old ones, with this is much more difficult. The wiring simply does not provide grounding.
It is better to entrust this work to specialists. If you decide to connect the oven with your own hands, you need to stretch an additional wire from the kitchen to a common shield on the landing and connect it to a suitable metal object.
Only if all the work is done correctly and accurately, you can guarantee the safe operation of a new oven cabinet.
Caution should be shown during the preparation of the electrical wiring, and when the actual or built.In oven is actually connected. First of all, this concerns personal safety.
Since the electric oven is characterized by high energy consumption, it will need to be carried out by an additional branch using an intact wire with a section of a current.For.Bonding of about 2.5 or 4 kV. Mm, if you came across an oven with a capacity of more than 3.5 kW.
Connect a live core through a separate machine, to which you can throw an electric hob of. The characteristics of automatic protection are selected depending on all the loads coming on it with a 10%margin.
So that the further operation of the electric oven is safe, you will need to correctly mount the grounding. This is not a problem in your house. But in the apartment buildings of the old building, a separate core will need to independently ground on the tire of the general electrical panel.
If we are talking about a technique of relatively low power up to 3 kW, and the wiring in the house is reliable and designed for modern loads, the use of standard Euro.Zoomers is allowed to install oven cabinets.
If there was no factory fork on the wire of the device, it can be placed yourself. You will need a fork of the euro sample with a ground plate. The corresponding core of the cable will be connected to it (usually it has a green or yellow braid). The remaining two wires are tightly pressed by terminals to brass contacts.
To the power cable supplied from the distribution box according to the same scheme, the socket is connected under the oven.
Some oven do not even have wires for inclusion in the network. In this case, it will need to be purchased and mounted on the corresponding terminals.
For work, the VVG wire will be required (if the sections of the veins are at 2.4 kV. Mm is enough) or PVS. Such a length so that it can be pulled from the oven to the nearest camshaft.
The color marking scheme of the wire and terminal panel is shown in the table.
How to connect a supply cable on your own
So, we have chosen a way to connect our priority kitchen devices. But our power cables are connected conditionally. We will find out how to do this for real. Traditionally, we will consider separately, oven and hob.
For an oven (with a power of not more than 3.5 kW, p = 3.5 kW) you need to purchase a piece of cable PVS 32.5 and a regular household fork for 16A. The length of the cable should be such that the cable is not stretched after the connection. When joining the fork (we agree, the cable has brown, blue and yellow veins), it is important to connect the yellow (yellow-green) core to the ground terminal. The procedure for connecting the phase and zero is as follows: the brown vein was the phase, blue is zero. The phase can be determined by the phase indicator (any household appliance does not respond to an order of order of phase-zero-if the TV plug is inserted opposite to the current position, then the TV will still work, however, it will be better, follow the operating conditions of this electrical appliance). Next, a small plastic cover is removed, at the cable connection site.
There we will see the connection for each cable veins.
Weak the attachment as follows: l is the phase, n-zero, land sign. Yellow (yellow-green. These are the colors of the Earth from the point of view of electricians) according to the colors of the veins. It is very important: the colors of the veins in a fork when combined Earth-Faz-Nol, must correspond to a similar combination in the connected device. If in the phase’s fork is a brown cable vein, then in the oven is a brown vein. Similarly, with zero and earth. Purely on colors.
Hob. As a rule, the models of the hobs are universal. This involves the connection of both 220V and 380V. The transition to one and the other voltage is realized by installing the appropriate jumpers. In most hobs, at the place of connection of the supply cable (convenient plastic cover), you can see a similar connection scheme:
In the case of an apartment where the dedicated voltage of 220V is obvious (in the case of a private house, with 380V, electricians adapt the power outlet on the hob on 220V).
In order for the hob to work from 220 V, the jumper should be installed according to line 3 of the connection scheme. For voltage 380V, select line 1. It can virtually look like this:
With regards to the supply cable, it is better to use PVS 36 (except when the cable in a smaller cross.Section is 34mm 2). In any case, it is recommended to adhere to the principle. The section of the supply cable cannot be less than the cross.Section of the cable in the outlet (the wires protruding from the wall, to connect the hob). Can. As mentioned above, the hob is a capacious consumer of electricity. With a power of 7.3 kW (p = 7.3kw), it is necessary to install a socket and a fork designed for current 32a.
The combination of flowers lived a cable with the ground, phase and zero completely similar to the case of an oven.
When connecting the battles of the oven and the hob, the brand of the PVS cable was indicated. PVS is a flexible multi.Core power cable in PVC isolation. But with an unusual connection with the wiring cable (and this is in most cases the VVG-HG brand cable, with monolithic inflexible veins), it would be more effective to use a similar brand cable. In terms of simplicity of connection. Possibly. From the point of view of operation. All the same we are dealing with household appliances, and they have some mobility. The monolithic cable is designed for immobility, the probability of breakdown of the veins is, but not big. The probability of breakdown of the connection places inside the device is already higher. Therefore, a multi.Core cable (PVS) is more convenient, in this case.
When performing work with electrical equipment, strictly carry out security measures from electric shock.
Roset installation schemes
The connection of the power point can be done in the same way:
- Open installation. Provides for the use of an overhead outlet on the wall. Openly mount power points without fail on wooden walls. This is regulated by PUE. It is forbidden to cut into a tree both wiring and sockets. By concrete, brick, gas blocks, an open installation method at the discretion of the master, if this fits into the overall concept of the interior of the kitchen.
- Hidden way. Involves inserting the outlet into the wall. This method is more often used in the implementation of major repairs in the kitchen or until finishing, since the work is rather dirty. We will have to pretty damage the tiled kitchen apron. However, for a master with experience, this is not a problem.
From the point of view of fire safety, the open method of installation of sockets is more preferable. In addition, they can be easily built into kitchen cabinets or table.
Important! If the panel and the oven have electric forks on the power cables, they cannot be cut off. By this you violate the warranty rules and lose it. Therefore, two connection options.
Option 1. There are no electric forks
We have two household appliances, with cable circuits for connecting power. It is very correct to do it:
Prepare the cables of household appliances for connection. To connect panels and ovens, use electric cords, type, PVS. The cords of the cords are multi.Wing. For better contact at the ends of the cores, you need to install compression sleeves or contact terminals.

Installation of sleeves requires a special tool, but it is worth it to ensure a reliable connection.
High.Quality connection of the panel ugly panel connection
To connect powerful household appliances, forget about twisting and rations. We use special terminals, under the name, barrier terminals.
If you need beauty, we hide the block in the distribution box, which we select in appearance.
Is it possible to connect the oven cable to the block of the hob panel?
The hob has a rather powerful block for connecting. In theory, you can connect the oven cable to this block. But only in theory. In practice, it is better not to do this. The hob is much more expensive than the barrier pad and you do not need to use it to turn the wires.
The result of connecting devices without forks and outlets
We get such a connection. The supply cable is connected to the barrier. Power cords from the hob and oven, are connected to the same barrier block in compliance with the color of the veins. Compliance of flowers lived their purpose, look in the documentation.
Note. Some models of built.In equipment are not equipped with power cables. For them you need to buy a flexible supply cord, the desired section, for example, PVS.
Option 2. Electric forks (fork) is
Important! Connection by type of fork-rosette is permissible if the current strength when operating the device is not more than 32 amperes. If the device is more powerful, the contacts of the sockets will heat up and the fire is possible.
In this case, we use looping outlets. From the outlet for the hob, we lay a train, a cable of the same cross.Section, put a socket and connect the oven.
I repeat, the total power of the panel and cabinet should not exceed the capabilities of the cable. First calculation (above), then a train.
What is the difference between an independent oven from the dependent
Oven can be divided into 2 groups. Dependent and independent. They differ in the design and the method of connecting to electricity.
Dependent models are installed in niches of specially designed furniture. Oven and the hob are placed over the other. They have a single system of connection to electricity and the general way to control. You can’t use them separately from each other. Such devices are widely represented in the household appliance market.
Independent devices gradually displace dependent. They are distinguished by convenience, ease of installation and use. Oven and the hob are not connected with each other, they can be controlled separately. They have no common wires, which facilitates the process of connecting. The method of managing each device can be different. Touch, keyboard, remote.
RCD and automatic
The rules of operation of powerful kitchen equipment imply the use of such a device in the network as a protective shutdown device (RCD) and automatic. This will prevent accidents with a possible violation of the integrity of the conductors and protect the current.
The machine is selected in accordance with the type of hob. If the technique is characterized by average power, a single.Phase automatic machine is mounted on the network by 20 A. If the technique consumes from 4 kW per hour, then the voltage cutter must be purchased by 32 a. In this case, the RCD should be selected one point higher than the automatic. If the switch, for example, is characterized in 32 A, then the protective shutdown device must be purchased with 40A parameters.
Select the technique and elements of the connection for the presented kitchen equipment should exclusively electrician. Independently engage in such issues, without even the basic knowledge of such things, is life.Threatening.
Connection of the induction hob
Connection Consider by example induction hobs Electric Panel (Electrolux). Such a panel 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 kV. 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.
How To Install Stove Range Cord 3 or 4 Prong
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.
As for the cable, through which the induction stove is connected, in this case it all depends on the configuration. If the supply cable is in the kit, then it is enough to connect it to the terminal block directly on the induction stove, and then to the purchased power fork or in the terminal block. Depending on the selected method of connecting the induction stove.
If the cable does not make the kit, then it must be purchased separately. When purchasing a cable, it is necessary to turn to its cross section. It must correspond to the connected load. It is necessary to purchase a flexible three.Core cable with a section of 4 or 6 kV. Mm for nominal currents 25 and 32 and, respectively.
In order to avoid errors, connecting the cable to the plate itself, as well as to the plug fork, it is recommended to perform according to the generally accepted color marking: brown or black-phase conductor, blue-zero conductor, yellow-green-protective grounding conductor.
If the cable is already connected to the terminal block of the electric stove, then it is necessary to check the correctness of its connection. At the terminals of the induction stove, the following marking of the conclusions is usually indicated:
Two.Phase and three.Phase induction stove connection
Certain types of induction hobs may provide for two or three.Phase connection to the electric network. If a three.Phase entry is made in the house, then such an electric stove is connected, as the manufacturer recommends. To two or three phases of the wiring of four or five.Core cables.
A three.Core cable is connected to a single.Phase household electric network, and special jumpers are installed in the terminal block on the induction stove, which usually come in the kit. If there is no jumper, then the connection to two or three phase terminals is carried out by the wire corresponding to the load of the electric stitch.
It should be borne in mind that if the kit includes a cable for a two- or three-phase connection, then it is not designed for single-phase inclusion, since when a single-phase connection of the induction stove, the load on the phase conductor increases to the total load of all phases.
Therefore, when using the four (five) phases on the stove for connecting to a single.Phase network, the cables are connected to the stove, and at the other end of the cable, when connected to the fork or in the terminal block, the phase conductors are shaken together and connected to one phase of the mains.
Either a new three.Core cable is purchased, which has a sufficient load ability for single.Phase connection of an electric stove.
Hobal panel Electric power kW
So, it is worth picking up a hob with such power that the cooking time is fast, but released by heat. Optimal.
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:
Induction hob is the most modern type of equipment for heating food in the kitchen. Its average power is about 7 kW. However, keep in mind that this is the consolidated power of the device.
Due to the fact that cooking on the induction surface takes a minimum of time, the simultaneous work of all disks almost does not occur. And even if this happens, a short period of peak energy consumption is rapidly replaced by inaction, since the cooking has already ended. The soup was boiled, the fish was fried, the kettle boiled.
Thus, although the power of the induction plate is equated to the power of the usual electric stove, due to heating exclusively the bottom and lower part of the dishes (and not the air under it), electricity is consumed only for heat treatment of products. It is important to note that energy saving requires the use of special dishes in cooking.
Cable for electric stove
The correct choice of a cable for an electric stove is primarily important for electrical safety. The choice of cable for the slab depends on the power of the stove itself, as well as on the type of network (single.Phase, three.Phase).
In a single.Phase network, a separate cable with copper veins is connected to the plate from the circuit breaker to the plate. The cable section for the electric stove is selected based on the rated current of the machine (table. 1), which in turn is selected based on the calculated load.
