12.3. How to install electrical wiring: Choice of materials and equipment

Installing electrical wiring is a crucial step in building a home. The process involves choosing suitable materials and equipment, in addition to complying with safety standards. This chapter of our guide will guide you step by step on how to accomplish this task efficiently and safely.

Choice of Materials

Materials for electrical installation include wires, cables, circuit breakers, switches, outlets, and conduits. The choice of these materials should be based on quality, durability and compliance with technical standards. Here are some points to consider:

Wires and Cables

The choice of wires and cables depends on the electrical load they will have to support. Correct sizing is essential to avoid overloads and possible fires. The wire gauge, which is its diameter, determines the amount of current it can carry. Larger gauge wires are needed for high wattage appliances such as ovens and air conditioners.

Breakers

Breakers protect the electrical installation against overloads and short circuits. They must be chosen according to the total load of the circuit they will protect. There are different types of circuit breakers, including single-pole, two-pole, and three-pole, each suited to a specific type of circuit.

Switches and Sockets

Switches and sockets should be chosen based on their quality and design. They should be sturdy and safe, and match your home decor. The location of outlets should be planned to ensure easy and safe access to power points.

Conduits

Conduits protect wires and cables from physical damage. They must be robust and resistant to moisture. The choice of conduit material (PVC, metal, etc.) depends on the environment in which it will be installed.

Equipment Choice

Equipment for electrical installation includes manual and electrical tools, such as pliers, screwdrivers, drills, saws, among others. The quality and safety of this equipment are essential for the success of the installation.

Hand Tools

Hand tools, such as pliers and screwdrivers, are used to manipulate wires and cables, tighten connections, and install components. They must be robust, comfortable to use and electrically insulated.

Power Tools

Power tools such as drills and saws are used to make holes and cuts necessary for installation. They must be safe, efficient and easy to use. The use of personal protective equipment such as safety glasses and gloves is essential when using these tools.

In summary, the installation of electrical wiring is a task that requires technical knowledge, planning and the use of quality materials and equipment. By following the guidelines presented in this chapter, you will be well on your way to building a safe and energy-efficient home.
