In my basement I have a line coming out of the breaker box; it has its own
breaker. The line serves both lighting and wall sockets. The first item
after the breaker is a GFI socket.
Why is a GFI placed on this kind of circuit?
The US National Electric Code requires GFCI protection for receptacle
outlets in unfinished basements. If that circuit supplies a receptacle
outlet in an unfinished portion of the basement the GFCI is required.
