Abstract
A new type of ground fault circuit interrupter (GFCI) with reverse wiring protection preferably includes a pair of fixed contact holders, each having a contact at one end; a pair of movable contact holders, each having a fixed end and a movable end, each of the movable ends having a contact; a movable assembly that moves between first and second positions, wherein the first position is a position in which each of the contacts of the fixed contact holders makes contact with one of the contacts of the movable end of one of the movable contact holders, and wherein the second position is a position in which the contacts of the fixed contact holders are separated from the contacts of the movable contact holders; an electromagnetic resetting component, which, when energized, causes the movable assembly to be in the first position; an electromagnetic tripping component, different from the electromagnetic resetting component, which, when energized, causes the movable assembly to be in the second position; and a control circuit, which, upon detection of a fault condition, energizes the electromagnetic tripping component, and which, upon detection of a reset condition, energizes the electromagnetic resetting component.
