During the installation of leakage protection socket, attention must be paid to the selection of power consumption of corresponding appliances. The power of leakage protection socket should be slightly higher than that of electrical appliances. When installing the leakage protection socket, use the wiring pliers to peel off the insulation layer at the input end of the wire, insert the terminal, and screw it tightly to prevent poor contact from causing a fire. Pay attention to the wiring of the live wire, the neutral wire, and the ground wire. Do not make mistakes. If the serial connection is made and the connection is wrong, the future maintenance work will be very troublesome and the consequences will be more serious. After installing the leakage protection socket at home, it is better to try it. First, test to see if it can work normally. After it is verified that there is no problem, use it normally.
