Now many homes have installed a leakage switch, which consists of a leakage protector and low-voltage circuit breaker, if the electrical overload or short circuit, it will automatically trip, and can not close the power supply.At this time, should check leakage protector into, out of the pile head and into the line voltage, if there is no problem, and then respectively disconnect each group out of the line, check whether there is an internal line fault.If there is no problem, but still can not send the power, you need to replace a new leakage switch.Above work, had better let professional electrician handle.

Four conditions are likely to cause fire of household appliances:
