Protective Device Having A Thin Construction

A compact electrical wiring device comprising:

• a housing including a front cover member, a back cover member and an electrical isolating member disposed between the front cover member and the back cover member such that a front interior region is formed between the front cover member and the electrical isolating member and a rear interior region is formed between the back cover member and the electrical isolating member, the electrical isolating member including a plurality of electrical isolation compartments that are accessible via the front interior region and protrude into the rear interior region, the plurality of electrical isolation compartments including at least one ground contact compartment;
• a plurality of user-accessible terminals and a ground plate disposed on the electrical isolating member in the front interior region and accessible via the front cover member;
• a printed circuit board (PCB) assembly disposed in the rear interior region, the PCB assembly being coupled to a plurality of line terminals and a plurality of load terminals accessible via an exterior of the housing, the PCB assembly including a first PCB surface facing the back cover member, the first PCB surface including a circuit arrangement comprising a plurality of electronic components, the PCB assembly including a second PCB surface facing the electrical isolating member, the second PCB surface including a toroidal fault sensor coupled to the plurality of line terminals, a solenoid actuator coupled to the circuit arrangement, and a circuit interrupter configured to movably engage the plurality of user-accessible terminals to provide electrical continuity between the plurality of line terminals, the plurality of load terminals and the plurality of receptacle contact structures in a reset state and movably disengage the plurality of user-accessible terminals to interrupt the electrical continuity to effect a tripped state, the toroidal fault sensor, the solenoid actuator, the circuit interrupter and the plurality of electrical isolation compartments being nested within the rear interior region such that a distance from the ground plate to the back cover member is less than or equal to about one inch.
