Ground fault circuit interrupter

A ground fault circuit interrupter comprising:

• at least two conductive wires having a common input terminal and respectively an output terminal;
• an AC-DC converter connected electrically with said input terminal of said two conductive wires, said AC-DC converter supplying DC to related circuits;
• a switch circuit electrically connected in series with said two conductive wires for cutting off output current to said output terminals of said two conductive wires;
• a first annular magnet and a second annular magnet respectively for said two conductive wires to pass through to get inductive current, a first coil and a second coil respectively wound on said two annular magnets for sensing an inductive signal and sending out the inductive signal to said output terminal;
• a signal treating and controlling circuit getting DC from said AC-DC converter and receiving the inductive signals from said first coil and said second coil and then outputting its controlled signal;
• the connecting point of the input terminal of said switch circuit and an output-controlling terminal of said signal treating and controlling circuit connected in parallel with a manual switch driving circuit for electrifying said switch circuit and an electronic switch driving circuit.
