Electrical Contractors are licensed professionals or businesses specializing in the design, installation, and maintenance of electrical systems in buildings. They manage projects from start to finish, which includes hiring and supervising electricians, procuring materials, and ensuring all work adheres to local electrical codes and safety regulations. Their services range from wiring new constructions and installing lighting systems to performing complex repairs and upgrades on existing infrastructure. Essentially, a contractor is responsible for the overall project, while electricians perform the actual hands-on work under their direction.
