Basically, an electrician can work in two jobs – residential and commercial. As the name implies, residential electricians are specialized in fitting a home for electrical wiring and investigating and repairing electrical problems in a home. Commercial electricians, on the other hand, specialize in carrying out electrical installations and repairs for office spaces, retail stores, and other businesses. Now, you have to simply decide whether you want electrical work done in your residence or commercial property and choose an electrician likewise.
