Abstract: A permanent-magnet ground fault circuit interrupter plug with self-diagnosing function having an enclosure and a permanent-magnet mechanism encased in the enclosure.

Abstract: A new type of switching mechanism for a ground fault circuit interrupter (GFCI) with reverse wiring protection preferably includes two pairs of fixed contact holders, each member of each pair having at least one fixed contact at one end; a pair of movable contact holders, each having an end having one or more of movable contacts, each movable contact being arranged for contacting one of the fixed contacts; and 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.

Abstract: The present invention relates to a reverse wiring protection device for ground fault circuit interrupter that includes a tripper and control circuit. The tripper comprises: a pull rod with flat, a L-shaped latch, a balance frame coupled with the latch moving up and down with the pull rod, a trip coil, a plunger and a contact switch (K) which is capable of energizing and de-energizing the trip coil. The reset can't be depressed when an installer or user miswires the line and the load.
