Through the different types of electrical cables the electric current is transported from the service box to the circuits of the house. We will see which are the best cables for domestic electrical installations.

In a domestic installation there are different sizes of electric cable necessary to transport the electric current, also called cable sections. For example, an air conditioner requires more current to operate than a lamp. Therefore, the wire cross-section connecting the air conditioner will be larger than the wire cross-section connecting the lamp.

Topflex H05V-K cable, also known as “pigtail”, is composed of a flexible copper conductor, class 5, and extra-slippery PVC insulation, to make it easier to handle, especially in small spaces in a house.

Among the most recurrent deficiencies, the reports identify: insufficient cable cross-sections, lack of circuits, absence of protection elements and non-existence of cable grounding.

Choosing the right cables for an electrical installation is very important to ensure the proper functioning of electrical equipment and appliances, and to guarantee the safety of the installations in your home. We are going to review with you what types of cables there are, what their differences are and what you should take into account when choosing them.

Our electrical system allows electricity to travel through three active conductors or phases -which are the black, gray and brown wires-, and a neutral conductor, the blue wire. To distinguish them from each other, a color code is used by means of the different colored plastic coating. This aids installation, makes the system safer and makes it easier to recognize them when making connections.

Before starting with the installation, calculate the amount of cable of each type that you will need and purchase a little more cable for possible inaccuracies. Remember that, at LEROY MERLIN, you can also purchase cut electrical cables, with a minimum and a maximum available. To plan the installation you want, you can draw on paper the layout and locations of each complement (sockets, light bulbs, etc.). This way, it will be easier for you to calculate how much material you need.

Electrical Cable Protector

For safety reasons, electrical cables should be protected in the home. The best way is to hide them, which does not mean that it is necessary to embed them in wall cavities, but it is advisable, at least, to keep them in tubes that are visible but do not expose the cables.

One solution is to hide the conductors in conduits. These can be glued to the wall or simply nailed in place. You can also choose their color, and even paint them according to the decoration of the room. They can also be inserted into the baseboards that have slits on the inside to store the cables.

In the case of chases (embedded pipes), the conductors are protected with a flexible black hose called “macaroni”. This facilitates the transport of the cables through the chases and protects them from the material used to cover the holes.

Just like the pipes, the conduits that house them must meet certain requirements. The general requirements stipulate that the routing must always follow vertical and horizontal lines. Instead, lines can be drawn parallel to the edges of the walls. This system makes it easier to locate the pipes in case of failure.

Outdoor electrical installations can have many uses. Usually, these installations are there to increase our general comfort in our home. They can also be used to create light sources in your garden, on your patio or under a pergola. Ideal if you want to put lighting on your flowers, your garden decoration or if you want to spend pleasant evenings in summer.

You may also need external cables to power an extension of the house created at the bottom of your garden or simply a workshop. If you plan to install a swimming pool, it will also be necessary to have a power line, either to filter the water or to light the pool.

When it comes to protecting outdoor cables . The cable for the outdoor electrical installation has to be unipolar or multipolar, made of copper and with voltage of 0,6/1kV, the best solution is still to bury them.

Once you are sure of the layout of these, you can start digging trenches. Remember to make them deep enough with a minimum depth of 40cm, so as not to inadvertently cut the cables one day while working in the garden, for example.
