56,284 Abstract of the Disclosure A multiple-pole ground fault interrupter, enclosed in an insulated housing, formed with multiple compartments, includes ground fault detection circuitry for detecting ground fault current that can be a personnel hazard. The ground fault interrupter includes a single trip solenoid assembly having multiple windings, each winding corresponding to one of the poles. The trip solenoid is mounted on a printed circuit board and electrically connected to the ground fault detection circuitry disposed thereon. The printed circuit board together with the trip solenoid assembly is disposed in a single compartment which reduces the amount of interconnection wiring between compartments, which, in turn, results in a reduced cost to manufacture the device. The use of a single trip solenoid assembly also results in the use of less components which further reduces the cost of manufacturing the device.
