When the second switch box 2 and the first switch box 1 are respectively connected with the zero line and the live line, the second main wire 23 and the first main wire 13 of the second switch box flow reverse currents, and the induction magnetic fields generated in the mutual inductor 261 cancel each other, so that the mutual inductor 261 does not generate induction currents, and the leakage protection electromagnetic release 263 does not work to keep the second switch mechanism and the first switch mechanism closed. When the leakage occurs, one of the second main wire 23 or the first main wire 13 is short-circuited, so that no current passes through the other main wire, the current of the other main wire normally flows and the mutual inductor 261 generates induced current, and the generated induced current is amplified by the power amplifier 262 to drive the leakage protection electromagnetic release 263 to shrink and release, so that the second switching mechanism and the first switching mechanism are disconnected.
