12.1 How to install electrical wiring: Planning the electrical installation

The electrical installation is one of the most critical parts in the construction of a house. Good planning and execution of electrical wiring ensure safety, energy efficiency and comfort for residents. Here's a step-by-step guide on how to plan and install electrical wiring in your home.

Step 1: Planning

The first step to a successful electrical installation is planning. This involves identifying the number of light points, sockets, switches and other electrical equipment that will be needed in each room. In addition, it is important to consider the location of furniture and appliances to ensure that power points are in convenient locations. Planning should also take into account the capacity of the electrical circuit and the amount of energy each appliance consumes.

Step 2: Choice of materials

The choice of materials is another crucial aspect of planning. This includes selecting high quality wires and cables, junction boxes, circuit breakers, outlets and switches. The quality of the materials used in electrical wiring is critical to the safety and efficiency of the installation. It is important to choose materials that comply with technical standards to ensure the safety and durability of the electrical installation.

Step 3: Drawing the wiring diagram

Once you have decided on the number and location of the power points, it's time to draw the electrical schematic. This is a diagram showing the layout of electrical circuits, the location of light points and outlets, and the routing of cables. The electrical diagram helps to visualize the electrical installation and serves as a guide during the installation phase.

Step 4: Installation of conduits

Conduits are tubes that protect electrical cables and facilitate their installation. The installation of the conduits must be done according to the electrical diagram. It is important to ensure conduits are installed correctly to prevent damage to the cables during installation and to facilitate future maintenance or wiring changes.

Step 5: Installing the cables

Once the conduits are installed, it's time to install the cables. The cables must be pulled through the conduits according to the wiring diagram. It is important to ensure that the cables are properly insulated and that there is no stress on the cables during installation. In addition, it is important to check that the cables are properly grounded to prevent electrical shocks.

Step 6: Installation of junction boxes, sockets and switches

Junction boxes are used to connect different cables and to accommodate switches and sockets. The installation of junction boxes, sockets and switches must be done according to the electrical diagram. It is important to ensure that junction boxes are properly closed and that outlets and switches are properly installed and grounded.

Step 7: Electrical Installation Test

Once you have installed the electrical wiring, it is important to test the installation to ensure that everything is working properly. This includes checking the voltage and current at each power point, and checking the operation of switches and outlets. Any issues detected during testing must be corrected before the installation is considered complete.

In short, installing electrical wiring is a process that requires careful planning, choosing high-quality materials, and meticulous execution. By following these steps, you can ensure a safe, efficient and durable electrical installation in your home.
