How to connect an electric oven and hob

Electric stoves and ovens are often used in the home kitchen. Moreover, the choice of the type of stove does not depend on the presence of gas in the house. However, these are powerful electrical appliances and the recommendations for their connection must be followed. It should be noted that the wiring must be designed for the power of these consumers in order to avoid emergency situations. In this article we will talk about the intricacies of connecting to a network of kitchen electrical equipment.

Decide on a model

If you have both an electric oven and a hob installed, the first thing you need to do is decide on the models and recommendations of the manufacturers. What to look for when connecting:

1. In some cases, the stove and oven are connected independently of each other, but if these are models from the kit of the same manufacturer, you need to look in the instructions, maybe they should be connected.

2. Connecting the cord to the electric stove, depending on the manufacturer, the cord may be removable or non-removable. In models with a built-in cord, Bosch has such, there is no way to replace it, it is fixed in the plate, if you need to extend it, you will have to cut it and connect it using terminal blocks, sleeves or in another way.

Mains connection

Typically, household outlets withstand currents up to 16A, such a current is consumed by appliances with a capacity of up to 3.5 kW. Therefore, if the power of your stove and electric oven is in this range, then you can connect to a wall outlet.

Powerful boards may require availability three phase inputif this is not the case, you will have to get out of the situation by changing the connection of the heating elements, including everything in parallel. Then the power is likely to go beyond 3.5 kW. Then you need to connect the wires directly to the machine with a current of up to 32A. It is selected in accordance with real consumption and a small margin (20-40% will be more than enough), a circuit breaker with marking type C32 is suitable.

It is worth noting that there are 32A plugs, they are quite large in size, and their pins are of an unusual round shape, and rectangular. They are connected as follows:

The connection diagram for a different number of phases and the magnitude of the voltages should be indicated on the device body or in the instructions. Type such:

Please note that each of the contacts is numbered, and the diagram indicates where jumpers should be installed.

In the lower or upper part on the back side there is usually a window through which the connection is made.

Jumpers can be set up to you, according to the common type of network in a particular region. Pay attention to the photo, factory-made copper jumpers similar to tires are already installed under the wires, but it’s better to make sure again.

In the example in the photo, each of the terminals is numbered. If there are no such jumpers, make them yourself from pieces of wire. In the photo, the wires are connected directly to the terminals, but it is better to do this using round terminals (cable lugs).

It might look like this:

Remember:

In the kitchen, especially near the stove, it is usually hot and humid, this exacerbates the functioning of both the cables and the appliances themselves. Hence there is an increased risk of electric shock.

In any case, the connection should be made through RCD, and the housing is highly desirable to ground.

To connect the electric hob and oven, you can use both flexible cables and monolithic ones, for example, VVG 3x2.5 and others suitable.

Do not connect a used cable. How to choose the exact cable section for a specific load An article was published on the site earlier.

The connection diagram of the electric stove through an RCD and an automatic machine to a single-phase and three-phase power network is shown below:

What can not be done when connecting an electric stove: tips and tricks

If during the repair in the kitchen you did not provide for the replacement of the wiring, you should be clearly aware that the old aluminum cables are not designed for such loads, even if electric stoves and ovens were also installed earlier. It is recommended to use copper so as not to lay the cable in the wall after finishing work can be laid by external methods, for example in the cable channel.

The line should go directly from the opening machine and only an electric stove and an oven are connected to it.

You can’t connect the stove and oven at the same time through tees or extension cords - anything will fail.

If you reconnect an old electric stove - replace the plug, probably it is old-style and has already worn out. This will take neither time nor financial means, but will improve contact and reduce the heating of the outlet, and this will save you from problems in the future.

Installation

Embedded models are very popular right now. They fit perfectly into a set of kitchen furniture, but you need to take into account the dimensions so that everything goes well. It is worth saying that simply pushing an electric oven instead of a kitchen table will not work. It is necessary to maintain small tolerances for the normal functioning of the devices. They also perform ventilation roles, cooling the case.

The image below shows approximate sizes:

• the distance from the bottom of the oven to the floor is 5-8 cm;

• from the side panels of the cabinet and kitchen furniture - 5 cm;

• between the back wall and the wall - 4 cm.

Conclusion

To summarize - how to connect an electric oven and hob:

1. A separate power supply cable should go from the input machine, nothing else is connected to it.

2. The plate is connected to an RCD and a separate circuit breaker.

3. When connected through a power outlet - the plug must be able to enter and stay steadily in it, stoves with power up to 3.5 kW are connected to a regular 16A outlet, and more powerful to a large 32-40A outlet or direct to the machine.
