Mainly the indoor circuit wiring and electrical, switch, socket and lamp installation behind the single-phase household distribution box meter. Construction personnel who carry out electrical installations should hold a certificate. The distribution box should be separately wired and supplied according to the different power of the indoor electrical equipment; air conditioners, electric water heaters, etc. should be separately wired and installed with sockets. When wiring, the color of the phase line and the neutral line should be different; the phase line of the same house
(L) The color should be uniform (red, green, yellow), the neutral line (N) should be blue, and the ground wire (PE) must be yellow and green. Single pipe and single circuit, wiring and circuit distribution must be carried out according to company budget and regulations.

4: Four rooms and two halls: 5 network cables, 5 telephone lines, and 5 closed circuits.
5: Each unit only installs two surround sound lines in the living room.
4. Construction considerations
1: According to the position of the electrical equipment in the design drawings, the direction of the pipeline, the elevation, and the position of the switch and socket should be determined.
2: When wiring the strong current power line, it must be matched strictly according to company requirements and design.
3: The laying of dark lines must be piping. It is forbidden to replace the yellow wax pipe into the bottom box and the distribution box instead of the lock, and to prohibit the yellow wax pipe from replacing the threading of the pipe and the elbow. (No exception for ceiling light cable)
4: The power cord and the weak wire should not be worn in the same wire tube. Strong and weak lines are not allowed to pass each other through the bottom box.
5: The horizontal distance between the power cord and socket and the weak wire and socket should not be less than 500mm.
6: The parallel distance between the power cord and heating, hot water and gas pipes should not be less than 300mm. The cross distance should not be less than 100mm.
7: All the wires passing through the tube are prohibited from the joints in the line tube. The joints and parallels should be set in the line box, the joints should be firmly connected, and the insulation tape should be evenly wrapped.
8: The resistance between the wire and between the wire and the ground must be greater than 0.5M ohm.
9: The socket panels of power supply, TV and telephone in the same room should be on the same level, and the height difference should be less than 5mm.
10: Splash-proof sockets should be installed in the kitchen and bathroom. The switch should be installed on the wall outside the door.
11: The indoor power box must ask the customer to replace it with a 16-bit power box. Leakage protection switches must be installed in the kitchen, bathroom, and socket circuits. It is not allowed to install a general leakage protector in front of the main switch.
12: When the tube enters the box or box, a lock must be installed. The requirements for the number of PVC thread pipes to be threaded are: no more than 4 wires per pipe for 16 lines.
13: The socket installation must fire from left to right. Above is ground.
14: The zero line and ground line of all loops are forbidden to connect in parallel with each other.
15: Light control wiring arrangement: 3 switches in the living room main light, 2 switches in the dining room light, dual control switches must be placed in the main and secondary bedroom, the living room and the hallway
16: The power supply of the electric water heater in the bathroom must be set separately.
17: The outlet pipes of the ceiling spotlights and downlights must be connected to the corrugated pipe through the circular tee. Bare naked wire is prohibited
V. Laying of flexible line technology for Deyi PVC general medium-sized line pipe
(1) Process flow
Position the Spring wire, bury the box stably, lay the pipeline, and thread the pipeline.
(2) Construction method
1: elastic thread positioning
According to the design requirements, determine the position of the switch box, socket box and distribution box on the wall and position the elastic wire, and mark the size.
The wiring should be minimized as far as possible; beautiful and tidy.
2: Stable buried boxes and boxes in the wall.
Check the exact position of the wire box and the distribution box according to the design position when entering the site, and use the cement mortar to fix the box and the box properly. After the cement mortar has reached a certain strength, it will take over into the box and the box.
3: Laying pipelines
When pipe wrench or hacksaw is used to break the pipe, the section of the pipe mouth should be perpendicular to the center line, and the pipe connection should use a straight head. A special bending spring is used for cold bending. When the pipeline is laid vertically or horizontally, a fixed point is set every 1m or so; the bending part should be set at 300-500mm at each end of the arc. When the pipe enters the box or box, one pipe and one hole are required, and the pipe and the hole are connected with a matching pipe end joint and an internal lock nut. The horizontal distance between the tube and the tube is kept at 10mm.
4: Pipe threading
First check whether the locks of each nozzle are complete. If they are damaged or missing, they should be replaced or replenished; the lines with long pipelines and more bends can be blown with an appropriate amount of talcum powder to facilitate threading; After that, two people pull the wires at both ends of the line and keep in touch with each other, so that they can cooperate with each other when pulling and sending.
