An “electrical power system” can be defined as a network of electrical components used to supply, transform, transfer and distribute electrical energy. An “electrical wiring system” instead, is responsible for powering specific elements within a system, that need electricity to work.

Therefore, the main purpose of an electrical wiring system is to satisfy the user’s needs and requirements, while coordinating the various components, such as the lighting, heating, and other systems, always complying with protection and safety standards.
A good electrical wiring system doesn’t only need to fulfill the purposes for which it was installed, but must feature a very high level of safety, quality, and flexibility, that will allow an easy maintenance in time, while guaranteeing a continuous and reliable power supply.
