1. , a kind of enhancement mode has the ground-fault interrupter of reverse wiring protection function, it by loam cake (1), insulating support (3), base (5), be installed in grounding rack (2) between loam cake (1) and the insulating support (3), be arranged between insulating support (3) and the base (5) and the circuit board (4) that is contained in the base (5) combines;

  • Be respectively arranged with power firestreak output conductor (14) and zero-power line output conductor (15) in the left and right sides of insulating support (3);

    Be provided with socket blade (16,17) at the two ends of power firestreak output conductor (14), be provided with fixed contact (24) therebetween;

    Be provided with socket blade (18,19) at the two ends of zero-power line output conductor (15), be provided with fixed contact (25) in the middle;

    On circuit board (4), be welded with the sheet metal (29) that links to each other with power firestreak input screw (31), the sheet metal (30) that links to each other with zero-power line input screw (32), be used to detect the differential differentiating transformer (33) of leakage current, a pair of differential differentiating transformer and the power supply input sheet metal (29 of passing,

         30) the moving contact arm (34 of Xiang Lianing,

         35), be used to make power firestreak/zero line output conductor (14,15) with moving contact arm (34,35) electric power connection/or release assembly that disconnects and the assembly that is used to stop ground-fault interrupter power input/output reverse wiring mistake;

    It is characterized in that;

    Set up a pair of elasticity fixed contact back of the body (210,200) respectively in inboard, the centre position of described power firestreak output conductor (14) and zero-power line output conductor (15);

    One end of the elasticity fixed contact back of the body (210,200) links to each other with power supply output conductor (14,15), and the other end links to each other with fixed contact (24,25) on the power supply output conductor;

    Set up a pair of moving contact (26A, 27A) at the other end of described moving contact arm (34,35), make the other end of moving contact arm (34) in left side be provided with two moving contacts (26,26A), the other end of the moving contact arm (35) on right side is provided with two moving contacts (27A,

         27);

    A pair of power firestreak output conductor (212), zero-power line output conductor (211) on described circuit board (4), have also been set up;

    One end of power firestreak output conductor (212) is provided with a fixed contact (24A), and the other end is welded on the circuit board and links to each other with power firestreak;

    One end of zero-power line output conductor (211) is provided with a fixed contact (25A), and the other end is welded on the circuit board and links to each other with zero-power line;

    A pair of moving contact (26,27) on the described a pair of moving contact arm (34,35) is corresponding with a pair of fixed contact (24,25) on a pair of power firestreak that is arranged on the described insulating support left and right sides, the zero line output conductor (14,15);

    On the moving contact arm (34,35) another to moving contact (26A, 27A) be arranged on described circuit board on another is corresponding to a pair of fixed contact (24A, 25A) on power firestreak, the zero line output conductor (212,211).
