safety first
Stand on a plastic or dry wooden bench, easily cut the live wire with insulated wire cutters and wrap it with electrical tape. Don't let go of the zero line, treat them equally! Remember, don't touch the metal parts, safety first!
Wires, lights and sockets have all been replaced with new ones.
Wires, lights and sockets are all new! Thanks to your skillful hands, this home is brand-new!
Measuring line zero fire line
The light switch is fully open, and the multimeter is blocked! Measure neutral live wire to see if there is a short circuit. Zero resistance? Don't worry, it may be a short circuit! Under normal circumstances, there should be resistance!
2P leakage switch over 50A
Is this the right line? Then find a 50A or above 2P leakage switch and connect the household wire to the lower end of the air switch. Simple and safe!
Huanxinyan
Untie the neutral tape of the household wire, peel it off and connect it directly to the upper end of the leakage switch. Then, the firewire also operates as above! Everything is ready, and the home circuit is refreshed!
