How to make a plug for the oven

INSTALLATION OF THE COMBINED SOCKET FOR OVEN AND HOB

The scope of delivery of the Prima combination socket includes. The mechanism of the socket, support. mounting pad and bolt.

First of all you need to fix the support on the wall. Near the power cable for the hob, as shown in the image below.

Quite often the wall, where is located the electric outlet for the stove in the kitchen, is concrete or brick, so first we attach the support to the mounting area and mark the mounting holes.

After that, with the help of a peorator, in the marked places, we make holes for fasteners. Normally a 6 mm drill bit is used for this.

Fixing dowel nails caliper on the wall. You can also use any other suitable fasteners, such as dowels (plugs) and self-tapping screws. If the wall material is soft, such as wood or foam block, you do not need to make holes and can fix the support at once with self-tapping screws.

Disassemble the socket mechanism. To do this, unscrew the bolt on the front side (see the picture below). picture below)

As you can see, inside there are two separate, unrelated mechanisms, one is “Euro” socket 16A, and the other is a power socket for a hob or stove 32A. Connecting them we will deal with a little later, now it is necessary to mount the socket mechanism in the caliper. on the wall.

To do this, the slide has a special “ear”, and at the platform, where you installed the socket, a ledge that goes into the “ear”.

Then you need to tighten the screws. that are located where the sockets are mounted to the platform. These bolts go through the mechanism and screwed into the support, where they specially made landing holes with threads, thereby reliably linking together support and mechanisms.

Before proceeding to the connection, always make sure that there is no voltage on the input power cable. Disconnect the power supply can be in the electrical panel, most often it is enough just to find the appropriate circuit breaker, it is usually the largest size, most often 32A-40A.

For your convenience, below we have prepared a diagram that clearly shows the order of wiring.

How to connect an electric hob and oven: the choice of cable, socket and plug, circuit breaker and wiring diagram

When making repairs in the kitchen very often the question arises: how exactly to connect the hob and oven so that it is safe and does not require a lot of effort and money? Manufacturers and sellers of electrical appliances always recommend to entrust the connection to professionals, but most often this service is expensive or an additional option imposed by the seller to the buyer.

As practice shows, the question of connecting the oven and stove hob can be solved independently even by a person who has never been connected to electricity, but who has a desire to understand it and at least a minimum set of tools.

Next we will understand this difficult matter: how to connect the hob and oven?

Which socket you should choose for the hob and/or oven

It depends on the characteristics of the appliance. Hobs and ovens come in both single-phase and three-phase versions and can be rated from 2.5 to 10 kW.

Single phase connection

Cooking and/or ovens up to 3 kW.5kW are plugged into a standard 16A/220V socket. An oven will in most cases have a standard cord and a 16 amp plug (if wired independently), so you’ll only need a socket. Hobs don’t have a plug, so you have to match both the plug and the socket.

For the more powerful single-phase models of electric stoves and ovens from 3.6 to 7 kW, a power socket with 32A/220V characteristics and, if necessary. A special 32A plug.

Three-phase connection

A three-phase hob and/or oven requires a 380 V supply and a 20 Amp three-phase socket, if the power is not higher than 3.5 kW or 32 Amp for a powerful cooker from 3.6 to 7 kW. If the oven and/or hob is not supplied with a plug, you will also need a 3-phase plug with the appropriate amperage.

Thus, you can not replace the special sockets for hob and oven with models for lighting and small appliances.

Power calculation

The power calculation is made according to the recommendations for electrical installation design on the basis of the basic tables in PUE 7 (Electric Appliance Installation Regulations, rev.7). Here is this table in beautiful form.

As you can see from the cross section and power table:

Electric cable with copper conductors 4 mm, normally works (not overheated) if the maximum power of running appliances does not exceed:

make, plug, oven
  • 6 mm² copper cable holding power: 7.4 kW with concealed wiring and 11 kW laid in a box or openly.
  • A 4 mm² copper cable can handle the following wiring capacities: 5.9 kW with concealed wiring and 9 kW with exposed wiring.
  • 4 mm² aluminium cable holds: 4.6 kW and 7 kW respectively.
  • 6 mm² aluminum cable for 8.5 kW and 5.7 kW.

Important at! It is these calculations that should be a prerequisite for selecting hob and oven wattages.

If you did not have a choice of appliances in terms of power, and you have been given them as a gift, then to connect the hob and the oven correctly, you must lay two separate electrical cables from the switchboard to the place where the appliances are installed, choosing the cross section of cables according to the same table, only in reverse, by power look at the cross section.

Connecting a plug for a stove or hob

Cooking hob or electric oven. are often the most power-hungry electrical appliance in any home. Their average power consumption is 7-8 kW, which corresponds to a current of 32-38A, so the standard, familiar Schuko plug (see “Standard”) is a good starting point. The image below) for connection to the network is not suitable, because it is designed for a current of 16A-25A.

In addition, the power plug to connect the stove or hob to the network, must support cables or wires with a large cross section. 4-6 mm.sq. We talked in detail about selecting a cross section of electrical wiring for the stove in the kitchen HERE. Be sure to study this material before reading further.

Nowadays, there are several different varieties of household sockets and plugs that meet these requirements. In our country, to connect the electric stove or cooktop, it is customary to use a connector RSH/VSH32. (cm. image below)

Such a plug and socket combination exists both for connection to single-phase mains.220V, as well as to use two- or three-phase network. Many models of electric stoves, with the store, come with this plug, often included as well and the corresponding socket.

Extremely recommend that you use to connect it is ready-made set, it happens that the power plug of one manufacturer, not suitable to the socket of another.

On sale, you can often find two kinds of plugs for the stove, black. made of carbolite and white. plastic. Oddly enough, the white ones are of higher quality, but they also cost more. Although internally and structurally they are identical and connected in the same way.

Connecting the oven to the power grid

Nowadays it is more and more common to use electric ovens. This raises a number of questions on how to correctly connect the oven to the power grid. This article is devoted to how and with what to bring power to the outlet and make a connection of the oven to the mains.

To carry out electrical and construction work, we will need the following tools:

• voltage indicator device. It is best to use a multimeter for this purpose; • A box cutter, pliers, or a special tool to cut the cable/conductors and strip the insulation; • Phillips/plane screwdriver or an electric screwdriver with a set of bits; • Tools for making a hole to install the mounting box and preparing the cutouts.

First of all, we would like to remind you that you should only connect the oven and carry out electrical installation and construction work in full compliance with safety regulations. Before starting installation work, it is necessary to turn off the power in the switchboard. To do this, you need to lower the lever of the diffuser, and then use a multimeter to check the presence of power. If the value on the dial of the device has not changed, then you can proceed to the installation work.

How to connect an electric oven up to 3.5 kW

To find the right cable, socket and plug to connect the oven, if one is not included, you need to determine the wattage of the stove. To do this, refer to the electrical appliance data sheet, which will specify the rated power and wiring diagram of the oven.

Many people wonder what kind of cable is needed to connect an oven with a capacity of less than 3.5 kW. To solve this problem will approach a flat three-core cable with conductors cross section of 2.5 mm2, for example, cable VVG-P 3h2, 5-0, 66 production JSC Kavkazkabel, consistent with GOST 31996-2012. The cable of this plant is color-coded with white, blue and yellow-green (w/z) strands. In addition, in order to connect the electric oven to the mains, you will also need:

• subcabinet (mounting box); • The socket for the connection of the oven for a current of 16A with a ground contact type SCHUKO (German standard); • A plug (if it is not included with the oven).

To provide additional protection against electric shock, it is recommended to make connections in the switchboard through a differential device (RCD, differential circuit breaker). It is recommended that such a device be provided in advance or installed in a panel. If you also intend to install an electric cooktop, the oven and the hob can be connected to a single fuse box, selected according to the total load.

Before installing the cable, you must perform construction work to prepare the walls for the cable and socket installation. The preparations for connecting the oven are carried out in the same way as described in our previous article Wiring the hob.

In the box we run and fasten the power cable VVG-P 3×2,5 to the intended location of the socket, which will be connected to the electric oven. At the same end of the cable in the mounting box must have a length reserve for reconnection.

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

After laying and securing the cable in the panel, connect it to the protective apparatus in the following order:

• Connect the cable wire marked white to the lower terminal of the differential circuit-breaker engraved 2; • the core of the cable with the color marking of blue to the bottom terminal engraved N of the differential circuit breaker; • yellow-green wire of the cable. To any screw terminal on the grounding bus.

After that, we do finishing work and install and wiring. Strip the cable in the mounting box and connect the socket:

• connect the cores of the cable VVG-P 3×2.5 with white and blue insulation to the outermost terminals of the socket. If the socket terminals are marked L and N, then connect the white wire to the terminal marked L, and the blue to N; • green-yellow core to the center terminal marked or PE.

If the oven is not supplied with a plug, it must be connected. To do this, the pre-purchased plug, rated at 16A, disassemble and pass the stripped and pressed wire of the oven through a special hole in the housing. Connect the wire:

• brown-insulated wire (black or other), brown-insulated wire (black or other), yellow-insulated wire (black or other).) and blue to the outer bolt connections of the plug; • the core with yellow-green insulation to the central screw joint of the plug with the grounding marking.

Then fix the wire and assemble the plug. You can now carry out a functional test by connecting the electric oven to the socket and connecting the power in the electrical panel (the disconnect switch lever must be pulled). If everything is working properly, you can install the oven in a recess specially prepared for this purpose.

How to connect an electric oven with power over 3.5 kW

At the moment, there are electric ovens on sale, the power of which exceeds 3.5 kW. In order to connect the oven to the mains with this power, we first need to answer a few questions: What kind of cable is needed to connect the oven?, what kind of wire is needed to connect the oven? And what cross-section of wire is required to connect the oven? To solve the first problem will approach 3-core cable with conductors cross-section of at least 6 mm2, such as cable VVG-P 3h6-0.66 production JSC Kavkazkabel, consistent with GOST 31996-2012. The cable of this plant has the following wire colors: white, blue and yellow-green (w/z).

For the decision of what wire is necessary for connection of the oven and what section of a wire is necessary for connection of the oven we recommend to use 3-core connecting wire with section of not less than 6mm2. For example, wire PVS 3×6 production JSC Kavkazkabel (color coding veins brown, blue, yellow-green).

In addition to the power cable and the connecting wire to connect the oven to the electrical grid, we need a socket to connect the oven and the plug, rated at 32 Amp.

Installation of power cable VVG-P 3×6 from the switchboard to the junction box and connecting it to the fuse is carried out exactly as in the previous version. But the socket must be connected as follows:

• a wire with yellow-green insulation to the center upper grounding-type terminal; • cores marked white and blue to the lower terminals of the socket.

To connect a 32A plug, take it apart and connect it in the following order:

• brown and blue insulated wires to the lowermost connector on the plug; • a wire with yellow-green insulation to the center (top) connector of the plug

If the connecting wire is not connected to the oven, connect it. To do this, remove the protective panel and pull the 3-wire PVS wire through a special hole in the bottom of the cabinet. Grind the insulation, crimp the multiwire cores with crimping lugs and make the connection:

• the core of the wire PVS 3×6 brown to the terminal marked L; • blue wire core to the terminal marked N; • The two-color (yellow-green) wire to the marked terminal.

If the terminals are not marked, refer to the data sheet that shows the connection diagram of the oven.

make, plug, oven

After connecting the wire, secure it with a staple and install the protective cover. We check by connecting the electric oven to the mains and powering up the electrical panel. If everything works without any problems, we mount the oven in a specially prepared niche.

We have wired ovens with different wattages. A visual representation of the installation and wiring process for ovens can be found in the video attached at the beginning of this article.

Wiring conditions

Here’s what I want to point out. In the photos of this article, the connection of the hob and oven are connected directly to the power cable, and both devices to the same cable. In terms of electrical installation, this is not correct. For the hob or electric stove must be laid a separate supply circuit with a separate ground. A modern oven, despite its size, has double protection and can be plugged into a simple (non-earthed) socket. In this example, the oven comes with a socket, which we cut off and connect directly.

But anyway, in my example, both the oven and the hob are connected to a common cable with a power terminal (block), designed for a large current in the circuit, below you will see a photo of it. I note that connecting an electric stove, cooktop on, so-called stranding, soldering or low-power terminals such as Wago, DANGER.

Work plan

Let’s divide the planned work into the following parts:

  • Preparatory work;
  • Preparation of electrics;
  • Connecting the hob;
  • Connecting the oven;
  • Installing the devices in place;
  • Checking Continuity.

Independent connection of the oven

When buying a built-in oven, sellers recommend trusting professionals to connect the equipment. But this service, even in the presence of normal wiring costs about 1500 (about 25), which is not bad. And if you have to pull the wiring from the switchboard, the cost increases even more, and solidly. But to connect the oven with their own hands can be an ordinary person who knows how to hold a screwdriver in his hands. With laying a separate power line is more complicated, but you can cope too. The only disadvantage of such actions you will not have in the passport the appropriate box. On the basis of this you can refuse warranty repair, if suddenly comes a warranty case. So the choice is yours.

Independent oven can be installed in a cabinet

Electric ovens come in two varieties, dependent and independent. Independent ovens come with the hob and are connected to the same power supply. They should be side by side, usually with the hob above the oven. They are connected with each other by cables, as the position of the oven controls affects the work of the hob. All requirements are detailed in the instructions and must be strictly adhered to.

Independent ovens are completely self-contained units that connect independently. The choice of installation location is also up to you. That’s probably why these models are more popular.

The wire and its parameters

In recent years, when laying electrical wiring and connecting household appliances are most often used copper conductors. Although they cost a lot more, but they are more convenient to work with, in addition, copper requires a much smaller core diameter than when using aluminum conductors.

Wire sizes are chosen according to the type of 220 or 380 V network, the type of wiring (open/closed) and the current or power consumption of the equipment. Usually copper conductors with a core of 4 mm (for line lengths up to 12 m) or 6 mm are used.

When selecting the type of cable to run from the switchboard to the socket, it is best to opt for solid conductors. They are more rigid, but more reliable. To connect the stove itself (to which you will need to connect the power plug), you can choose a flexible stranded wire: a single wire would be too inconvenient in this case.
