The socket of the water heater burned out, so I bought a replacement myself. Excuse me, please tell me the ground wire, live wire and zero wire. Can I connect at will? Can the water heater plug still be used after burning like this? There is nothing wrong with the plug, but remind your brother to choose the right socket. The quality of inferior socket copper is not good enough. If the power supply is used for a long time, it will heat up and burn out the plug and socket. In addition, I suggest you sand the oxide of the copper insert of this plug with sandpaper. In addition, the connection mode is Shangdi left zero right fire. It's strange that all the wires in your house are red and need to be tested with an electric pen. If there is any danger, I suggest calling the property!
