Abstract
A GFCI receptacle has a receptacle and terminals for connecting the connectors of that receptacle to an AC source, terminals for connecting the connectors of the receptacle to one or more other loads and an interrupter for disconnecting the source from the receptacle and the other loads in the event of ground current exceeding a selected level. For testing the interrupter, a manually operable supervisory circuit opens the interrupter and gives a visible indication of its operation. The supervisory circuit is connected between a hot connector of the receptacle and ground so that the visible indication will not be visible when the GFCI receptacle is installed improperly, thereby avoiding a false indication of proper installation.
