Power socket installation steps and precautions

Power outlet installation eight steps

First, the socket wire installation, the power supply wire must use the copper wire cross-section, the wiring must follow the "fire line into the switch, zero line into the lamp" principle, but also set the leakage protection device on the socket.

Second, determine the location of the socket installation, the general surface distance is preferably not less than 1.8 meters, the concealed distance is not less than 0.3 meters from the ground, the socket of the kitchen and bathroom should be more than 1.5 meters, and the air conditioning socket should be at least 2 meters. .

Third, the bedside of the bedroom is more than two plugs, and the kitchen and bathroom do more than three plugs.

Fourth, air conditioners, refrigerators, range hoods and other high-power appliances should use independent sockets, overload operation, easy to cause fire. The ground wire of the three-hole socket must be connected, and it cannot be made to be ineffective. Otherwise, if it leaks, it will cause electric shock. Set up several circuits to prevent a short circuit from using electricity in the entire room.

Fifth, you need to conceal the frame with the outer box of the socket, and then dig the hole according to the drawn frame line, the depth is equivalent to the thickness of the socket.

6. Fix the plastic plate at the bottom of the excavated pit, pass the unstripped three wires through the mounting box, and then fix the mounting box.

7. First peel off the zero wire head and connect to the socket terminal block, then peel off the fire wire head and connect to the socket terminal block, and finally peel off the ground wire head and the socket ground wire terminal block.

8. Carefully place the socket in the mounting box and install it.

Top ten precautions for power socket installation

First, the protective measures of the socket, there are often water and fume in the kitchen and bathroom. It is best to install a splash-proof box or plastic baffle on the socket panel to prevent short circuit caused by oil and water vapor intrusion. For families with children, in order to prevent children from touching with fingers or metal objects, it is best to use a safety socket with an insurance cover.

Second, the switch is improperly installed, especially the switch is installed on the flammable object, the sheath is scratched at the lead wire lead, so that the wire core is exposed or water vapor infiltrates, causing a short circuit, or an arc is generated when the switch is disconnected, causing a fire;

3. When the flammable gas used by the household leaks due to the leakage of the pipeline or the valve, and the flammable gas is mixed with the air to reach the explosion limit, opening or closing the electrical switch without the arc extinguishing device may cause a fire or explosion;

4. Insulation and stripping of the wire ends used for flat or screw sockets or multi-eye sockets. When it is too long, the bare part causes a short circuit; when it is too short, the conductor is in poor contact, the contact resistance is too large, and the overheating causes a fire;

5. The cross section of the power cord used for the socket is small and the power used is too large, causing the wire to heat up and catch fire;

6. The socket is pressed by flammable materials or the dust falls into the short circuit, or installed in a flammable and explosive dangerous place. When a plug is inserted or unplugged, a spark is generated to cause an explosion and fire;

7. The plug is not damaged in time, and the bare wire is used instead of the plug to cause a short circuit or spark, causing the combustible to catch fire;

8. The working voltage and working current of the lamp holder do not match the power of the socket used. Long-term overload, if the temperature is too high, it will cause fire;

Nine, when the lamp holder is installed, the lamp holder is twisted to make the wires twisted together, or the bare wire core is too much, and when it is scattered, it hits the other end and causes a short circuit fire;

10. The switchboard is not inserted into the box. When the fuse is blown, hot metal particles will splash, causing the combustibles below to cause combustion.

The above are the eight steps of the power socket installation and the top ten precautions. In addition, everyone must first close the main gate when installing the socket, so as to protect their own safety and avoid accidents.
