Connecting the electric cooker yourself - possible sources of error

Connecting the electric cooker yourself - possible sources of error


Connecting an electric cooker can be very simple or complicated.

The Biggest Mistakes When Connecting Electrical Appliances

In addition to overconfidence, incorrect or inadequate tools are the main reasons why something can go wrong with a connection. Ideally, only color-matched cables should be screwed into terminals. Nevertheless, nobody should go to work without a two-pole voltage tester. With this device, it must always be checked whether there is actually no voltage.

Furthermore, an insulated screwdriver is important, it also provides safety if, despite all caution, power is applied. In addition, tape should be at hand.

Safety When Installing Electric Stove

Basically, it is important to turn off the fuses of the stove. In most houses there are anti-tippers in the fuse box. Electricity flows when the lever is up. An "I" is visible. Power is interrupted when the lever is turned down and a "0" is visible.

Important: The cooker is usually protected by three fuses. So there are three belonging to the stove toggle switch down to fold. If it is not clear which fuses belong to the stove, they must all be switched off. For safety, the switches must be taped over. The measure prevents inadvertent switching on of the current.

Now it is allowed to unscrew the junction box of the stove and to measure with the phase tester the voltage between the poles and the earth. The earth is usually yellow-green-striped or red. These measurements must read every 0 volts.

Color Coding Issues

Ideally, there are five terminals in the box, into which five cables of different colors open. The three phases have the colors brown, black and gray, the neutral has the color blue and the earth the color yellow-green. These colors also have the cables coming from the stove. When connecting, only screw the cables into the corresponding terminals.

Older houses often have two black and one brown phase cables. Neutral and earth are as described. Here it is important to connect blue with blue and yellow green with yellow green. The assignment is irrelevant for the phase cables.

A bigger problem exists if there is no yellow-green cable in the socket. The earth used to be red and the neutral gray. The phase consisted of two black and one blue cable. There is therefore a danger of connecting the blue phase in the tin to the blue neutral conductor of the electric range. Due to this error, the stove is energized. There is danger to life.

Important: If there is no yellow-green conductor in the junction box, always have a specialist make the connection. Measurements must be made on live wires to determine the phases. This is not work for a do-it-yourself enthusiast and should be done expertly.

Caution with bridges

In the junction box, sometimes different contacts are connected, the specialist speaks of bridges. A connection between earth and neutral is normal. Likewise a connection between two neutral conductor terminals. If an electric cooker with 230 volts was connected to the can, there are usually also bridges between the phases. These must be removed at a stove with high current. There will be a short circuit if there are jumpers.

When connecting a 230 volt cooker to a high voltage cooker outlet, the phase line contacts must be connected. For these herds, only one fuse may be set to "on". The other fuses must be permanently secured with tape so that they are not accidentally switched on.

Never relinquish the strain relief

In each junction box there is a recess for the stove connection cable. There is a plastic part, which is attached to the box with two screws. The cable should be laid under this plastic part. The part must press the cable firmly to the edge of the box. Without this strain relief there is danger. One of the cables could become loose in the socket and result in a short circuit.

If there is any doubt as to how to connect, a specialist must make the connection.
