摘要:
A ground fault circuit interrupter (GFCI) yoke with integral grounding screw and simple staked ground receptacle stab arrangement provides the device grounding features. The mounting screws that are attached to the yoke by means of staples provide a wall box self-grounding feature. A push-to-test arrangement is provided by a neutral strap and test contact attached to the line receptacle stab through a current limiting resistor. Depressing a test button energizes the test circuit by electrically connecting the test contact with the neutral strap. The combination of the line and neutral receptacle stabs with the line and neutral moveable contact arms and the arrangement of the receptacle stabs in alignment with the receptacle plug-in slots allows the push-to-test and interrupter contacts to be assembled within the GFCI enclosure without additional wiring.

The neutral excitation transformer and differential current transformer (15,16) of a ground fault circuit interrupter device are mounted on a common electrically insulated support having downwardly extending pins for inserting into the printed wire board (18) of the electronic signal processor circuit. A metal can electromagnetic shield having four prongs extending from its bottom end is mounted to the support by means of three of the prongs while the fourth prong is inserted within the printed wire board for electrical connection with the signal processor circuit.

A compact operating mechanism for a ground fault circuit interrupter comprises a pair of main and reset slotted latches arranged under a crossarm and over a latch plate on a spring-loaded latch pin. The mechanism is reset by interference between a neck portion on the latch pin and a surface on the reset latch. The mechanism is latched by interference between the surfaces on a pair of upright posts on the latch plate and a surface on the main latch.

A ground fault circuit interrupter interconnect arrangement provides wireless connection with line and neutral main current terminals by insertion through an aperture in the interrupter magnetic sensor module to form a magnetic sensor plug-in subassembly. The electronics components and trip solenoid are mounted to the interrupter printed wire board. The magnetic sensor subassembly is plugged into the printed wire board for interconnection with the electronics components. This allows the interrupter to be assembled in a completely automated process.
