It is best to draw a CAD electrical lighting plane with exposed wiring. Thank you very much.

The positions of electrical appliances, switches and electrical boxes are marked in the original structural drawing in the floor plan, and the way of drawing lines is not clear about installation or installation. The installation method only uses the letters at the end of the line to indicate bare installation, bare installation and pipe threading, and the material label of pipe threading is the same.

The marks of distribution lines are used to indicate the laying mode and location of lines, which are expressed in English letters.

The marking format of distribution lines is:

a—b(c×b)e—f

For example, BV (2×10+1× 6) SC32-FC indicates that the line is a copper-core plastic insulated conductor, and two 16mm2 and 1mm2 steel pipes with a diameter of 32mm are buried along the ground.

Another example: BLV (3×16+/kloc-0 /×10) SC50-WC means that the line is aluminum-core plastic insulated conductor, and three 16mm2 and10 with diameters of 50mm are buried along the wall.

Here are some codes marked on the drawings. If you want some legends, you can leave me a message and email.

SC: steel pipe PC:PVC polyethylene flame retardant plastic pipe CT: bridge

WC: Buried laying along the wall WS: Buried laying along the wall CC: Buried laying along the roof F: Buried laying in the floor CE: Buried laying along the roof YJV: Cable SYV: TV line PE: Grounding (yellow-green) PEN: Zero line (blue) Line 3 (fire line): A (yellow) B (green) C (red).

KV: (voltage) KV: dispersed MEB: total equipotential LEB: local equipotential.
