Before you start with this item, do an important premise: for security and legislation, in order to design an electrical system must be a registered professional to its national register . If, however, we are about to build a house, before entrusting the job of designing the electrical system, it could be helpful for us to knock out a rough plan as to then develop and refine the technical.

Basically an electric system serves to transport, in a safe manner, the electrical energy in all the rooms in a house, in order to use it for common uses. The system starts from the delivery point installed by your electrical system and that the electrical contractor (which is usually placed in a location accessible easily of the property, often in the outer wall of a detached house or in ‘entrance of a building). Contractor must be provided by the electrical cables to the central box of the house, where you install the switches and general all security features such as the circuit breaker. Remember that electrical cords are passed in the special plastic pipes (corrugated tubes) for which we expect to pass the cables where they will have to pass the special corrugated pipes.


Time must be provided from the main power cables that carry the energy in every room of the house. The system is divided mainly into two branches: the driving force (electrical outlets) and strength light (all lights in the house) . In this way, there should be a fault in any socket, one can isolate the relative plant that is lacking without the light (and vice verse). The cable cross section of the driving force is greater than that of light (because the current consumed by the consumers connected to the sockets, is usually much greater than that absorbed by the lights). For added security, as in the kitchen and in the bathroom there is the greatest concentration of power users (furnace, water heater, etc.), you can design the system so as to bring in the kitchen and bathroom, two branches isolated from each of the other driving force , including the switch dis connector. In this way, the main users of the kitchen (oven, stove, etc) Are isolated from the rest of the household sockets.
