The power is out at home! ! Urgent! !

As for the air switch (leakage protector), I used to do my own experiments. When I connected the power cord of the air switch, the rubber at the end of the cord was not peeled clean. As a result, after the power supply was turned on, because the rubber current was not enough, it struck a fire and gave off heat, and finally it tripped. Push up, jump for a while, and finally find the reason as mentioned above. Look for it
