The first has to do with a deficiency in the design of the installation or network, many times the electrician masters do not put on a sheet of paper the planting of this installation, which consists of a plan or sketch to determine the distribution of dampers, electrical outlets, lighting, etc. Electricians are also sometimes called when the construction of the house is already very advanced, which forces them to mentally improvise the distribution of this network, leading to mistakes.
Another of the most common mistakes happens when you start with the laying of cables, either in their paths, moorings, or in the amount and caliber of them, causing short circuits, energy leaks to some element of the construction, such as conductive tubes, rods, or supply deficiency.
What are the most recommended materials for the electrical installation of a home?
The minimum materials required in the construction of a house are: registration boxes, dampers, outlets, lamps, etc. – and ducts where the wiring passes – which can be either metal for thick or thin wall or PVC, this being one of the most used.
Conductors are also needed, that is, cables with a plastic insulating sheath. The ideal metal for this type of conductor is copper, and there is no more.
In addition, 30-amp knife switches and load centers that use thermomagnetic switches are needed. Generally, taking into account the regulations, both switches must be installed. An element that is of the utmost importance and that few construction companies take into account is the use of the ground system, that is, to have an element that goes to the physical ground, which can be a copper rod or conductor buried in the ground and a bare cable that travels through all the pipelines of the electrical installation.
What can other advice be given to electricians to guarantee quality work?
A first tip is that when working, they do not do it on a wet floor or after having been in contact with water without making sure they are completely dry, because when handling electricity in this condition we are more susceptible to electric shock. Another basic advice is to cut off the mains supply and verify directly that there is no electricity supply, easily with a socket and a bulb.
There are some houses with a ring-shaped installation, where the power is still cut off, we can be the connector of this and receive a discharge. Therefore, you should always have an insulating element, whether on the floor, with rubber shoes, gloves, wood on the floor, or any non-conductive material.
