electrical contractor

An electrical contractor is a company which installs the electrical wiring, equipment, and other electrical systems throughout a building or a major part of it at the construction stage or later.

The installation can take place during construction or later in the building's life. Its scope is the building or a major part of it, and includes wiring, equipment, and other electrical systems.

A supplier of electrical connections provides connection equipment, while the electrical contractor installs the electrical system. Lighting installation identifies work specifically on lighting systems and fixtures.
