A wall outer, is a device that can be used to connect equipment that requires electrical energy. There are also wall outer types that have a different application, such as sending data transfer or removing vapors and gases from the connected equipment.
When connecting a wall outer in a home installation, it is important to work voltage free. You can do this by first removing the safety fuse of the group in question. Or by converting this fuse in the case of an automatic fuse. Then check with a voltage finder or multimeter whether you are really voltage free.
Connecting a wall outer:
You can connect a wall outer in two different ways: Pull wires from an existing wall outer or from a so-called junction box. You can see a junction box as a crossroad where several wires come together and split up. Here you can remove the power for your wall outer. For this you need three wires with a minimum thickness of 2.5mm²:
- Blue, the zero wire, this is taking care of the receptive overhead wire
- Brown, the de fasedraad, deze zorgt voor de stroomtoevoer
- Yellow/Green, ground wire, This is of great importance in order to use the earth switch properly.
Strip these wires with a stripping plier and make sure you do not damage the copper wire. Then place the wires under the terminals of the wall outer. The ground wire always comes in the middle and is marked with an ground (earth) symbol:
Then do the same with the end of the cables at another wall outer or split it off at a junction box.
What is a switched wall outer
A switched wall outer is a power point with a switch behind it. You often see this reflected in system ceilings where, for example, fluorescent boxes are still connected. This gives you flexibility and allows you to move the light points in the ceiling over time. However, it is wise to label the wall outer with "Switched WCD".
What is a wall outer with protective contact
An earthed outlet is connected to an earth leakage switch in the distribution board with a ground wire. An earth leakage switch measures the leakage current and if it exceeds a certain size, the current is cut off. An earth leakage circuit breaker works as the following sentence: If an electrical installation consumes more current than what goes out again, there is leakage current. This may be due to the voltage on the case. In the case of earthed equipment, this current flows away by the ground and the earth leakage circuit breaker will start. It therefore protects against electrocution and prevents fire in the event of a short circuit.
