●When the test button is pressed, if the circuit is normal, the leakage switch of the control circuit should be tripped immediately.
●If the test button is pressed, the leakage switch does not work. There are two reasons for this:
The first is that the neutral wire and the ground wire of the detected socket are wrongly connected to each other. In this case, the plug indicates that the connection is correct, but the leakage switch will not work.
The second is that the wiring in the tested socket is completely correct, but the leakage switch on the line fails and needs to be repaired or replaced.
●The method of judging that the circuit is completely correct and the leakage switch is normal
The indication of line status is correct. The leakage switch operates reliably when the test button is pressed.
