First: Indoor wiring mainly choose PVC insulated copper wire in tube, pipes material should flame retardant. Can use H03V-U or H03V-K.
The second: the cross-sectional area of copper wire:Below four square millimeter:
We can chose H03V-U,The single hard copper wire;Above four square millimeter : we can chose H03V-K, It is easy to wear longer line, join automatic air switch, socket and others has good maneuverability.
Third: family indoor dome lighting and socket are is better use two main line, wall lamp, footlights can be Shared with outlet line.
Four: careful!!!!! The joint of Line must be welded or set of copper pipe pressure!!
The choose of main line:
Main dome light: 2.5 mm2 can safely through 13 ampere current. 4mm2 can be safely through 19 ampere current.
Mains socket: 6 mm2 can be safe by 22 ampere current.
The chose of branch line:
lamps and lanterns can choose 1 ~ 1.5 mm2 HO3V-U (single hard line), Joining lamp holder, switch is more convenient,.
The cross area of socket will be larger It should 2.5 ~ 6 mm2, 19 soft copper thread of H03V-K is easy to operate.
