2, wiring must be piping, except hollow floor (hollow floor with sheath line), strong and weak electricity can't wear into the same tube.
The wires in the pipe should be in a loose state.
3. There shall be no connectors in the conduit. After the completion of water and electricity, the exposed threads of all switches and sockets must be wrapped with insulating tape to avoid the danger of electric shock.
4, when installing the power socket, should be left zero right phase (live wire), higher than the ground wire.
The live wire enters the switch and the neutral wire enters the lamp holder.
(Acceptance criteria) The phase line (L) should be red, the zero line (N) should be blue, and the protection line (PE) should be yellow and green. 5. The power supply, telephone, TV and other socket panels in the same room should be on the same horizontal plane, and the height difference should be less than 5mm.
6, toilet socket should be splash-proof.
7. The distance between the power socket and the ground is generally 300mm, and the distance between the switch and the ground is generally 1400mm. If there are special requirements, handle them according to special circumstances (such as wall-mounted air conditioning sockets).
8. Lighting line 1.5BV, socket line 2.5BV, grounding line 2.5BVR, air conditioner and oversized power cord 4BV.
Air conditioners and high-power appliances should be wired separately.
9. The gas pipeline (natural gas pipeline) must be exposed and cannot be sealed. If the pipeline must be moved, it must be done by the gas company.
10, wire tube, hot water pipe and gas pipe should keep a certain distance from each other, and shall not be close to each other.
