1. At the entrance of your home, you must install a distribution box with three protection switches for overcurrent protection and leakage protection. Because of the leakage switch, once there is leakage in the home, such as the electrical housing is charged, the human body is exposed to electricity, etc., the leakage switch will trip, thus ensuring personal safety.
2. When wiring indoors, the socket circuit and the lighting circuit shall be separately routed. The socket circuit shall be a single-strand insulated copper wire with a section of not less than 2.5 mm 2 , and the lighting circuit shall be a single-strand insulated copper wire with a cross-section of not less than 1.5 mm 2 .
3. For specific wiring, the plastic sheath or other insulated wires used shall not be directly buried in the cement or lime powder layer because the wires directly buried in the wall have been "dead" in the wall and cannot be pulled out. Once a certain line of damage needs to be exchanged, only the wall can be re-routed. When changing the line, there must be no joint in the middle, because the joint is directly buried in the wall. As time goes by, the insulating tape at the joint will age. Long-term burial in the wall will cause leakage. In addition, the wiring of most homes will not be constructed according to the drawings, and the accurate wiring drawing files will not be saved. When a wooden pillow is placed on the wall in the home, nails are nailed, and the wires directly buried in the wall may be damaged without paying attention. Even the nail nailed through the wire caused the fire line, the zero line short circuit, the light fuse fuse or the switch tripped, the electric spark generated when the short circuit was short-circuited burned the nail nail, and even caused a fire. If the nail is only nailed to the fire line, the nail is charged, and the person stands on the ground again, it is very likely that an electric shock accident will occur. Therefore, it should be buried in the tube.
4. The height of the socket installation is generally 0.3 m from the ground and the minimum should not be less than 0.15 m. When the socket is wired, the single-phase two-hole socket is connected to the left hole of the socket, and the right hole is connected to the phase line; Hole socket, the left hole facing the socket is connected to the working zero line, the right hole is connected to the fire line, and the upper hole is connected to protect the neutral line or the ground line. It is forbidden to connect the upper hole and the left hole with wires (this type of connection will trip the leakage protection during use).
5. The installation height of the wall switch is generally not less than 1.3 meters from the ground and 0.15-0.2 meters from the door frame. The wiring of the switch should be connected to the live line of the lamp or appliance being controlled. If the switch of the lamp or appliance controls the neutral line, it may cause electric shock when replacing the lamp. Therefore, it is forbidden to switch the control neutral line when wiring.
6. When the chandelier is installed, when the weight of the luminaire is less than 1kg, the flexible wire can be used for self-hoisting. The soft wire in the hanging box and the lamp cap must be knotted. When the weight of the luminaire exceeds 1kg, slings, hooks, etc. shall be used. The upper end of the bolt shall be unloaded with the embedded parts of the building, and the conductor shall not be stressed.
