PROBLEM TO BE SOLVED: To facilitate the specifying of an electrically leaked place by turning a power feeding switch OFF with the detection of an electric leakage and performing a control so as to store electric leakage information based on an electric leakage detection signal. SOLUTION: When an electric leakage is generated in any one place of a DC main power source 1-2, an AC load 1.1-3 and an AC load 2.1-4, an electric leakage detection signal is outputted to a control circuit 1-7. The circuit 1-7 received this signal judges and specifies in which place of plural loads 1-2 to 1-4 the electric leakage from electric leakage detecting circuits 1-A to 1-C is being generated and stores the place in a memory 1-7-2. Moreover, the circuit 1-7 transmits a control signal for interruping the conducting of electricity to the plural loads to an AC relay 1-5 to turn the relay 1-5 OFF. Furthermore, the circuit 1-7 transmits a control signal for displaying the specified and stored electrically leaked place to a display part 1-8. The part 1-8 displays the electrically leaked place based on the control signal. |
