ABSTRACT:
Ground fault circuit interrupter components, including a fault-sensing circuit and a relay, are enclosed within a housing having terminals for connection of the wires of a line cord extending from an electrical appliance or other electrical load for which ground fault protection is provided. Standard plug blades extend from the housing for insertion into a conventional electrical receptacle to connect the load to a source of electrical power, the circuit interrupter components being interposed between the wire connection terminals and the blades. The housing configuration and assembly provides an essentially waterproof enclosure for all elements between the line cord and plug blades which is preferably divided into two discrete compartments, one containing the wire connection terminals and the other the GFCI components. Thus, if the one compartment should develop a leak, the water-tight integrity of the other is still maintained. The line cord extends into the module through a resilient sealing grommet which may conveniently be interchanged with different size grommets to accommodate line cords of various diameters without changing any other components of the module. Assembly is simplified and facilitated by providing a one-piece body member, open at both ends, and connecting all other components as a single assembly for insertion into the body and fastening with screws at each end to sealably close the body openings.
