How to connect an electric stove yourself in a standard way and without an outlet, Hansa, Dream

ИFrom the article you will learn how to connect an electric stove yourself, diagrams and connection methods (without a socket and with a socket), wiring requirements, safety measures and much more.

What is the convenience of electric stoves

The main element in the kitchen has always been a stove, because without it the concept of “kitchen” loses its meaning. In gasified houses, gas stoves are mainly used, but recently more and more people prefer electric ones.

Electric stoves are easy to operate, do their job well, and are safe, but only if connected correctly.

When purchasing a new electric stove, many stores provide the services of an electrician who connects it.

Even if such a service is not provided, the sellers strongly recommend using the services of an electrician to connect the device.

And all this because a modern electric stove is a very powerful consumer of electricity, which means that special requirements are imposed on the safety of its connection.

But it is not necessary to call the wizard, even with basic knowledge in the field of electrics, it is quite possible to connect this device on your own, there are no particular difficulties in this, but some conditions must be met.

Features and conditions of the connection process

Copper wiring with a cross section of at least 4 mm must be laid in the house or apartment. sq. If the power of the plate is significant, then a wire of 6 mm is needed. sq. section.

Therefore, the wiring that will power the stove should be connected to the machine with the highest current value, or an additional powerful machine should be installed under it in the switchboard.

In this case, the current value of the machine must be one rating higher than this parameter of the plate in order to avoid critical loads. That is, when connecting a device with a current consumption of 20 A, a 25 A machine is used.

The last condition is the correct connection. The stove can be plugged into an outlet, which provides some convenience, allowing you to turn it off at any time.

But the socket and plug must be power, able to work under loads.

Be sure to ground the switchboard.

Also, through a plug and socket, you can connect not very powerful electric stoves.

If the device has a large power, then it is better to use a terminal block to power it. It is able to withstand heavy loads.

But such a connection is one-piece; to de-energize the stove, it will be necessary to turn off the machine.

But still, such a connection is more reliable and safe, so it is better to use it even when connecting medium and low power devices.

Another way to connect is “directly”. Suitable in cases where the manufacturer of the stove did not complete it with a power cable. In such cases, the wire coming from the machine can be connected directly to the stove, avoiding additional connections.

Safety Precautions

When connecting, it is important to take security measures seriously. Wiring, socket with plug or terminal block must be designed for significant loads.

The most important thing is to choose the right cable section.

All connections must be well tightened, loose bolts or screws are not allowed when connecting wiring.

It is also important not to confuse the wiring when connecting to a stove, socket, RCD plug and machine.

Let’s sum up a little.

In order for the electric stove to work with maximum safety, it is necessary to ensure the supply of electricity to it with the appropriate parameters – the wiring, the socket and the machine must withstand the load more than the electric stove creates, but the RCD in terms of current strength should be as close as possible to this parameter of the electrical appliance. And it is better if a separate line and an automatic machine are used to power the electric stove.

But compliance with the conditions is not enough, you still need to connect the wiring correctly. After all, the plates can work from a single-phase or three-phase network, there are also two-phase plates, and it is important to connect everything correctly.

Connection diagrams

It is good if the manufacturer has completed its products with a power cable. It will not be difficult to connect it, since it remains only to correctly distribute the wires in the plug or on the terminal block, but often such a cable is not available, and you have to purchase it separately and connect it yourself.

Next, we will consider how the cable is connected to a stove operating from a single-phase, two-phase and three-phase network.

Single-phase network connection

In the electric stove under the protective cover there are contacts to which the wire is connected.

For a single-phase network, this cable must be three-core.

One core is a phase, the second is zero, the third is grounding. In the cable, each core has its own color. It is important to remember that the core for zero is always blue or blue, and the ground is yellow-green.

In the plate, there are usually more contacts for connection, but each of them has its own designation.

All conclusions marked with the letter “L” are phase, no matter how many there are, zero is marked with the letter “N”, there may also be several of them, while grounding is indicated by the letters “PE”, usually this is one conclusion.

Knowing this, you can easily connect the cable. If, for example, there are several “L” outputs, and there is only one phase in a single-phase network, then you need to use the jumpers that come with the stove.

First, we connect the ground wire to the “PE” terminal, then – zero to the “N” terminal.

If there are several such conclusions, we use a jumper, connecting them together, and then we connect a blue wire to one of the conclusions.

The phase is connected last. We connect with a jumper all the conclusions marked with the letter “L” (if there are three, they are designated as “L1” “L2” “L3”).

After the connection, we connect the phase wire. In a three-core cable, it can be brown, gray or black.

Connection to a two-phase network

Rare, but still found method of connection.

The connection scheme to an electric stove powered by a two-phase network is somewhat different, since this requires a cable with 4 cores, two of which will be phases, the other two will be zero and ground.

The connection is made as follows: we connect the ground wire, then use the jumper for the zero terminals and connect the neutral wire.

If the plate has three phase outputs, then we connect two of them with a jumper and connect one phase wire to one of the outputs, and the second phase wire to the remaining third output.

Connection to a three-phase network

To connect a stove powered by a three-phase network, you need a cable with 5 cores, 3 of which will be phases, the other two will be ground and zero.

Again, first we connect the ground and zero, having previously closed the zero terminals with a jumper, if there are several of them.

We connect one phase wire to three phase terminals.

The colors of the phase wires may be different, but it is important to remember that the neutral wire is always blue or blue, and the ground wire is yellow-green.

With this in mind, you can easily connect the cable to the stove, no matter what network it works on.

Complete wiring diagram through a socket

Now let’s consider the complete scheme for connecting an electric stove, for example, let’s take a model powered by a 220 V network (single-phase), and we will lay a separate line for it.

First, connect it with an outlet. Before starting work, the switchboard must be de-energized.

So, first of all, we connect the wire to the machine on the switchboard.

We connect the phase and neutral wires to it, the earth must be connected to the ground of the house or apartment.

Regarding grounding – a little lower. Immediately after the machine, we connect the RCD in series and fix it.

Then the wire is pulled to the installation site of the outlet. This can be done in an open way (using a corrugated tube or a plastic box).

The socket and plug for a single-phase network must be power – three-pin.

When connecting the wires to the outlet, you should not confuse the wires. The earth must be connected to the ground contact, zero to the neutral contact, and the phase to the phase.

And be sure to make sure that the cable from the stove is connected to the plug in the appropriate way. It is very important not to confuse the wiring.

We fix the socket on the wall, it is important that it is at a distance from metal structures (pipes or radiators), it is not affected by heat sources, and water does not get into it.

Then we connect the power cable with the plug to the stove. After that, we carefully check all connections, they must be well tightened, all elements of the circuit must be securely fastened.

Next is a trial run. First, the machine turns on, then the RCD, and the stove itself.

After turning on the stove at full power, everything is turned off and all elements are checked for heating.

Connection without socket

Connecting the stove without using a socket, but using a terminal block is practically the same.

The wire is connected to the machine, then it crashes into the RCD circuit, and the wire stretches to the installation site of the plate.

A recess is made in the wall in which a protective box is installed. This box contains a terminal block.

A wire coming from the switchboard, as well as a cable from the stove, is supplied and connected to it.

They are fixed in the terminal block, it is important not to confuse which wire is which.

After that, the protective box is closed with a lid. Well, then – a performance check.

It is noteworthy that the wiring diagram for electric stoves is almost the same.

Many people know Hansa and Mechta electric stoves. Customers often ask how to connect them correctly.

Since there are many models of plates, it is difficult to guess which one you have purchased. But we have described all possible connection methods above.

See the power consumption and what kind of wiring your model is designed for (single-phase, two-phase or three-phase) and apply our recommendations.

The Hansa stove of a foreign manufacturer is connected to the network, like the domestic Dream stove. It is only important to choose the right wiring and all other elements included in the power line.

A few words about grounding

Now about grounding. Since the power of the device is large, grounding is necessary. One option for connecting the electric stove to ground is to use the common ground at home, if any.

To do this, it is better to contact the housing office and ask if your switchboard is connected to the ground at home.

If the answer is yes, it remains only to connect the earth wire to the ground of the shield.

It is not difficult to identify it – usually it is a thick wire. Connected to the shield body with a bolted connection. The earth wire is connected to this connection.

If there is no grounding in the house, but at the same time you live on the ground floor or in a private house, then grounding can be done by yourself.

In short, three rods are driven into the ground near the apartment, they are interconnected with a metal tape.

A steel wire is attached to this tape, which is laid to the apartment. And already a ground wire is connected to this wire.

Independent connection of the electric stove is described in general terms. In the process, many nuances can arise. For example, it was decided to connect the stove to the general network of the house, but it turned out that it was aluminum and was not designed for such loads.

Or the machines in the switchboard are weak. As an option – there is no grounding in the apartment and it is not yet possible to conduct it. All this must be taken into account, but with the right approach, these problems can be solved.
