[Answer] Wire selection: In order to prevent fire, repair and safety, it is better to choose the "national standard" copper core wire marked by the Great Wall. Wire cross-sectional area is generally 2.5 square millimetres for lighting and socket wires, air conditioning wires should not be less than 4 square millimetres, ground wires should be green and yellow double-color wires, and switching wires (fire wires) should be used. Red, white, black, purple and so on. But in the same home decoration project, the use of lines should be consistent.

Selection of threading pipes: flame-retardant PVC threading pipes should be used. The surface of the pipe wall should be smooth, and the wall thickness should reach the strength that the finger can't break, and there should be a certificate of qualification. You can also use the national standard special galvanized pipe to make the threading pipe.

Flammability and ruggedness; the switch height is generally 1200 to 1350 mm, 150 to 200 mm from the edge of the door frame, and the socket height is generally 200 to 300 mm.
