Abstract: The present disclosure relates to a reverse grounding protection circuit and a ground fault circuit interrupter. The reverse grounding protection circuit may include a power supply circuit, a leakage signal amplifying circuit, a leakage grounding detection circuit, a power supply indicator circuit, a manual detection circuit, a tripping mechanism control circuit, a reverse connection detection and execution circuit, and a power-on driving signal generating circuit. A ground fault circuit interrupter may comprise an interrupter body and a reverse grounding protection circuit in the interrupter body. The practice of the present disclosure may avoid the risk from reverse connection of the ground fault circuit interrupter and output of power of reverse connection, and thus improve safety of the ground fault circuit interrupter.

Abstract: A ground fault circuit interrupter includes a reset key, a reset mechanism, a conductive assembly configured to connect a power supply input side to a load side, a leakage signal detection circuit, and an electromagnetic tripping mechanism. The reset mechanism comprises a reset support and a support return mechanism. The reset support comprises a reset bracket and a support reset spring. The support return mechanism comprises a reset pole, a reset key spring, a compression spring, a reset block, a compression spring container, a reset slider, and a contact conductive part. The contact conductive part is disposed at a lower end of the reset slider and is configured to align with a position of a switch contact on a first PCB board. A state of contact or separation between the contact conductive part and the switch contact is configured to control an on-off state of the conductive assembly.
