Patent ID: 7498909

Claim:
An improved ground-fault circuit interrupter device having a reverse wiring protection function and being adapted for connecting to hot and neutral power lines and hot and neutral load lines, comprising: a cover; an insulating member; a base; a mounting and insulating plate disposed between the cover and the insulating member; an electrical component mounting member disposed within the base and located between the insulating member and the base; first hot and neutral output conductors disposed on two sides of the insulating member, the first hot output conductor having a first insertion plate and a first resilient stationary terminal carrier carrying a first stationary terminal, the first neutral output conductor having a second insertion plate and a second resilient stationary terminal carrier carrying a second stationary terminal; wherein the electrical component mounting member includes a differential transformer for detecting a leakage current, first and second moveable connector arms passing through the differential transformer and being adapted to be connected to the hot and neutral power lines, respectively, second hot and neutral output conductors, a disconnecting mechanism assembly for electrically connecting and disconnecting the first hot and neutral output conductors to and from the first and second moveable connector arms, and a reverse wiring protection mechanism, wherein the disconnecting mechanism assembly includes a solenoid, wherein the first moveable connector arm carries a first and a second moveable terminal and the second moveable connector arm carries a third and a fourth moveable terminal, wherein the second hot and neutral output conductors carry a third and a fourth stationary terminal, respectively, and are adapted to be electrically connected to the hot and neutral load lines, respectively, and wherein the first and third moveable terminals corresponds in position to the first and second stationary terminals, respectively, and the second and fourth moveable terminals corresponds in position to the third and fourth stationary terminals, respectively; a reset button; and a switch coupled to the reset button, wherein the switch includes two contact terminals which are closed when the reset button is pressed down and open when the reset button returns to its un-pressed condition, and wherein when the two contact terminals of the switch are closed, the switch forms a current path in series with a current path of the solenoid.
