We take electricity for granted and available everywhere in our houses. But it takes diligent planning and a professional installation to get electricity safely to where we need it. Handymen and amateurs can become a big safety hazard that threatens your life and property. Electrical installations, old or new, require professionals, such as electricien Noisy Le Grand, to be safe or to guarantee continued compliance with safety standards.
The electrical system of a house has many components. Many are invisible behind walls or in out-of-the-way places. The most important components of the electrical system are:
- The meter
It lives on the outside of the house near the main connection to the power pole of the power company. Meters measure the amount of electricity used inside the house by the various loads. Older meters have a spinning wheel and a readout that displays the amount of power used. New meters are digital. They display the electricity used on an LCD display.
- The fuse or main breaker box
The main breaker panel is near the meter. It contains the master breaker (or fuse) that protects all circuits inside the house. A number of secondary circuit breakers, in turn, protect the wiring that leads to individual electricity users in the house. Each breaker protects an individual wiring circuit, that is, a room, an appliance or another load. Breakers can be reset, fuses must be replaced.
- The circuits
All rooms of a house, appliance or other major consumers of electricity have a set of wires that run from the breaker box to the load. They need to be installed correctly by professionals, such as an electricien noisy le grand. Three insulated wires serve the individual load. One bare wire is the safety protecting the house against disastrous effects of a short.
