器。 In a tester that connects a commercial power source to the primary side of an isolation transformer and tests the operation of the earth leakage breaker in a power supply device that supplies power to the transfer device via the earth leakage breaker on the secondary side of the insulation transformer. , a resistor that is connected to the load-side electrical circuit of the supply device to flow a current having a ground fault current value at which the earth leakage breaker operates and a resistor to flow a current having a ground fault current value immediately before the operation are connected in parallel via a changeover switch. A tester for an earth leakage breaker, characterized in that the changeover switch is configured to ground each of the resistors individually and cause current to flow in a simulated manner.
