Wire Color Wire colors listed in the table below show standard colors (base colors). For wiring composed of two colors, the first color shows a base color and the second color a marking color. Example: The wire color of BW shows that its base color is B with a marking W.
BW Marking color Base color
Notice: For wiring identification, the same color, in principle, must be used for the circuit from the power supply to the load.

CAUTION
Be careful that allowable current differs between solid wires and stranded wires even if they are of the same gauge.
