Properly designed and properly executed wiring ensures safety and ease of use for many years. Therefore, you should think carefully about its location in advance. Before we get to the execution stage, we need to think carefully and imagine its further operation.
Designing wiring in a house or apartment, it is best to start with careful consideration of the location of furniture and appliances. So you should walk around the apartment with a pencil in hand and mark the places where we want to place lighting points and electrical outlets.
The next step should be to determine the estimated capacity of the equipment that we are going to use at home now or in the future. It is always better to slightly depend on the power threshold, as in the future it may turn out that our predictions are greatly underestimated.
When installing wiring, keep in mind that electrical wires cannot be placed on walls wherever you want. Wiring should be installed in areas least prone to drilling or other damage that may occur during the repair or renovation of the premises. It is also important, if possible, to install the wiring at right angles, as well as to avoid wiring in places with high temperatures (such as fireplaces).
Usually the places where cables are mounted are about 15-30 cm under the ceiling, 15-20 cm from the corner of the walls or the slope of the door.
In places where large power consumers are provided – such as electric heaters, washing machine, hob or hob with electric oven – it is better to use a cable with a cross section corresponding to the power of the receiver. Typically, all outlet lines have a cross-section of 2.5 mm2 and the lighting lines 1.5 mm2, however, if the device has more power, it may be necessary to use a thicker cable. Also keep in mind that some electric hobs, as well as boilers, require a three-phase connection – in this case, you need to lay a five-core cable.
A very important element of electrical installation is the protection of individual lines with circuit breakers (fuses). There are two main protections that are installed in the switchboards – a protective cut-out device (popularly called RCD) and a circuit breaker (fuse). It is better to leave their choice to professionals. It should be noted that the best solution is a separate protection of each room. This is especially useful during an accident when there is no voltage on a line that is connected to only one room.
When wiring, you should also keep in mind when laying wires in places where we plan to install a device in the future, such as electric shutters or air conditioning. The cost of the cable is low and avoids additional alterations in the future (usually related to grouting the walls and repainting already equipped rooms).
