Home Decorative Wire Threading Notes


1 Should wait until the PVC pipe is installed, and then unified wear wire.

Now workers are wearing a wire edge to take over, it is difficult to ensure that after the wire can be a smooth replacement.


2 The same loop wire should be inserted into the same root canal, but the total number of tubes should not be more than four.

The total cross-sectional area of the inner conductor shall not exceed 40% of the cross-sectional area of the tube.


3 Through the piping wire connector, should be located in the junction box, the thread to leave the remaining 150 mm.


4 The wiring should be the first rinse tin, and then wrapped with tape 7 laps, insulation tape should be evenly wrapped around.


5 Pipe threading should be color separation. Fireline red, zero line blue or black, and ground wire for the yellow and white lines.


6 For the socket, the zero fire or left zero fire, ground 2.5 square feet of two-color cord.


7 Connecting switch, screw mouth lamps, the first phase should be the first switch.
