Setting change operation while power is on

Answer

It is forbidden to change the characteristic when the breaker ON. Over current trip and earth leakage trip characteristics should be changed by a person with electrical expertise. Make sure that the power is OFF. Turn off (OFF) the main breaker, or turn off the circuit breaker when the characteristic setting will be changed.
Working in the live state may lead to man-made disasters such as electric shock and burns caused by an arc in the event of a short circuit.
