Abstract
A GFCI device includes a latch assembly provided with a rigid electrically conducting bar connected thereto such that when a user presses a reset button the latch assembly is moved toward a pair of contacts provided as part of a reset circuit to initiate a reset operation. When the electrically conducting bar on the latch assembly connects the pair of contacts, the reset circuit is closed and an actuator is activated to place the GFCI device in the latched, reset, condition. If the GFCI device is correctly wired, the latch assembly enters the latched state. If the device is not properly wired no power is provided to the actuator and the device remains in the tripped, or open, state.
