How to properly connect an electric stove

Electrical connection

Electrical appliances such as electric stoves and even more electric stoves with an oven with a power of more than 3000 W (3 kW) must have their own radial power circuits connected directly to the distribution board.

Power circuits of an electric stove

Small tabletop electric stoves and separate ovens (ovens), the power of which does not exceed 3 kW, can be connected to the ring circuit via a fused connector or even via a 13 amp socket plug. However, most electric stoves are much more powerful and must be connected to the mains via their own circuit.

Connecting an electric stove to a radial network

The electric stove must be plugged into a radial circuit — a separate wire directly to the control panel. A block must be installed between the plate and the shield. connection that is a double pole breaker.

electrical connectionWhen electric stoves with a power of up to 13.5 kW are connected to a panel with a socket, the radial circuit must be laid with a wire with a cross section of 4 mm2 with "earth" and two insulated wires and protected by a fuse of 30 amps or 32 amps mini- automatic. More powerful — up to 18 kW — cooking stoves can be connected to the same circuit, but from a wire with a cross section of 6 mm2 and with a 40-amp mini-automatic machine.

In each of these cases, it is safer to use contactless connection devices. Therefore, when installing a connection without a socket devices, the Rules for electrical work allow you to make a longer power circuit and use a fuse (instead of a miniature circuit breaker) for more powerful electric stoves. But in this case consult electrician.

Junction box or fuse switch to connect the electric stove

For connection, you can use a free (spare) fuse block in your box or install a separate fuse switch (switch) or a separate fuse, make sure the tube fuses fit.

Location of electrical connection block

A connection block for an electric stove must be located no more than 2 m from the stove. The unit must be easily accessible. For two-section electric stoves, one connection block can be used, which is connected by separate wires to the burner and oven sections, provided that the block itself is within 2 m of each of them. The connecting wiring must have the same cross-section as the radial power circuit.

The plate, which is not completely fixed, is moved from time to time for cleaning.Therefore, provide a suitable length of wire so that you can move it far enough away from the wall for such operations. A wire is connected to the terminal box, which is screwed to the wall at a height of about 600 mm from the floor. The stationary wire is laid from the terminal box to the connection block of the stove.

Connecting the electrical connection block

After choosing a place for the connection block, you can use the usual installation of an external installation box. If you are using a concealed installation, you must make a suitable recess in the plaster and masonry in which to place a metal back box.

Laying a wire to connect an electric stove

Run and fasten the wire the shortest way from the junction panel or fuse switch to the plate. If you prefer hidden wiring, make a groove in the wall (plaster and, if necessary, masonry) to the block connect the stove, from there cut the same channels to the burner and oven sections, if the plate is two-section, or for one wire going to a single terminal box.

Connection to the junction box

Insert the power wire and plate power wire into the device, tape and prepare the wires for connection.

The device has two groups of terminals: marked "Network" for the mains wiring and marked "Load" (load or device) for connecting the stove wire. Connect the red wires to the L (phase) terminals and the black wires to the N (neutral) terminals. Place green-yellow cambric over the two "ground" wires and connect them to terminal E (ground). Close the rear case of the device with the front panel.

Link to the plate

Electrical connectionWhen connecting the wiring to the burner and oven section of the stove, follow the manufacturer's instructions. For a loose plate, run the wire down the wall from the plate connection block to the terminal box that has terminals to connect the two wires. Remove the wires of the wire from the connecting block and insert them into the terminals, then insert the wire wires from the plate into the same terminals (in one terminal — one color) and tighten the clamps. Close the box with the front panel.

Connecting the switch box

If it is connected to a fuse located in the shield, connect the red core to the block terminal, the black to the neutral bus, and «Earth», after putting a cambric on it, to the grounding bus. All other connections will already be made. Be sure to turn off the power before starting these jobs, and remember that even then the wire from the meter to the main switch remains live.

If the plate is powered by a fuse box, fix it with screws to the wall near the shield. Insert the wire from the stove into it and prepare the wires for connection. Attach the red wire to the phase terminal of the fuse block (or mini machine in a single-line shield), the black-on neutral terminal, and the "ground" core in the cambric to the "ground" terminal.

Prepare test leads — one red and one black of solid 16 mm2 cross-section stranded wire with double PVC insulation.(If this wire is too thick for the terminals of the switch block, use a wire with a cross section of 10 mm2, but keep the meter wires as short as possible.) Strip 25 mm of each wire and connect them to the corresponding terminals of the main isolation switch: red — on L (phase) and black — on N (neutral). For grounding, prepare a piece of solid stranded wire of the same length and the same section with a green-yellow cambric applied and connect it to the «ground» terminal of the panel, preparing to connect to the common ground terminal. Do not connect independently of the power supplier's common ground terminal.

Place the appropriate fuse in the holder and insert a block into it. Label the fuse holder with the chain and close the cover.

Connect to the network

The new circuit must be checked by a professional electrician and his employee's conclusion of compliance with the Electrical Work Regulations presented to the relevant electricity company when it requests connection to its electricity network. Do not make such a connection (which should be done through the meter) yourself.

It is likely that it will not be possible to connect two sets of wires at the same time. — from the panel and from the new fuse — to the meter and possibly, you must install a terminal box with enough terminals to connect all the wires. Electric companies provide such payment services (before starting, it is recommended to make relevant inquiries in it).
