Steps:
1. Find the power supply, pull down the switch, and then remove the socket panel with a flat screwdriver to expose the fixed screwdriver.
2. Use a Phillips screwdriver to remove the fixed screwdriver (generally use a Phillips screwdriver, and use a single screwdriver), pull out the panel, and remove the power cord with an electrician's pliers.
3. Wrap the exposed power cord with insulating tape and put the power cord inward into the junction box.

1, position is too low
When installing a socket, many families think it is too high and unsightly, and will install it in a lower hidden position. However, Dr. Xia Dong from the Institute of Electrical Engineering, Chinese Academy of Sciences said that when mopping the floor, water could easily splash on the socket, leading to leakage accidents. According to industry regulations, the exposed socket should be no less than1.8m from the ground. The concealed socket shall not be less than 0.3m from the ground. The socket of kitchen and bathroom should be more than 1.5 meters from the ground, and the socket of air conditioner should be at least 2 meters.
Step 2 Install at will
The power cord must use copper wire section. If you live in an old house, you must replace the original aluminum wire with copper wire. Because the aluminum wire is easy to oxidize, the joint is easy to catch fire. A survey shows that the incidence of electrical fires in houses using aluminum wires is dozens of times that of copper wires. In addition, for the sake of beauty, many families will adopt the way of slotting and burying wires and laying concealed pipes. Xia Dong reminded that when wiring, the principle of "live wire enters the switch and zero wire enters the lamp holder" must be followed, and a leakage protection device should be installed on the socket.
3. Lack of protection
There is often water and oil smoke in the kitchen and bathroom. It is best to install a splash box or plastic baffle on the socket panel.
Step 4 share
This practice will overload the electrical appliances and cause a fire. It is best to use independent sockets for high-power appliances such as air conditioners, washing machines and range hoods. Generally speaking, it is best to install four sets of sockets in the bedroom, one for every 2.5 square meters in the living room and one for every 1.2 square meters in the kitchen.
Precautions for installation:
1, the installation height of the socket shall be installed according to the design requirements when specified in the design; When the design is not clear, it should generally meet the following requirements: the socket with safety door is not less than 0.3M；; The outlet without safety door shall not be less than1.8m. It is recommended to buy the outlet with safety door as much as possible, because the price difference between them is not big.
2. Bathrooms or other damp places should use well-sealed waterproof and splash-proof sockets. (Note: The socket with safety door is based on the ordinary socket, and a plastic baffle (safety door) is added in front of the metal reed of the jack. Three hole socket, when inserting the plug, first insert the grounding pile head (slightly longer) into the hole, and the mechanism in the socket opens the other two hole doors. The two-hole socket must be inserted into the socket pile head at the same time before the safety door can be opened, so as to prevent children from inserting metal objects by mistake and causing safety accidents. )
3. When the socket is installed, its panel should be straight and close to the wall. Moreover, the wiring (phase) should conform to: single-phase two-hole socket, the right hole or upper hole facing the socket is connected with the phase line (live wire), and the left hole or lower hole is connected with the zero line; Single-phase three hole socket, the right hole facing the socket is connected with the phase wire (L, live wire), the left hole is connected with the neutral wire (N), and the upper hole is connected with the ground wire (PE).
