In the circuit diagram, the material, thickness and color of all wires are represented by symbols. The wire code helps to understand the circuit diagram.
For example, AEX 0.85 L represents blue, heat resistant and low voltage automotive wires, with a nominal number of 0.85. L represents color by the color code.
0.85 the size of the wire is represented by a nominal number. AEX represents the type of wire by symbols. (because AV and AVS are divided by size (nominal number), so they are not pointed out.
1 types, symbols and materials
AV and AVS are only different in the outer diameter and thickness of the cladding. AEX is similar to AV in thickness and outer diameter, and AEX is different from AV and AVS on cladding material.
2 color code table

Note: in the 2 color code, the first color is the background color and the second color is the marker color.
For example, "GW" means that the background color is green and marked white.
