What do the color markings on electrical cables mean?
Electrical Cable and Wire Color Markings. Non-metallic (or NM) 120 V and 240 V electrical cable comes in two main parts: the outer plastic sheathing (or jacket) and the inner, color-coded wires. The sheathing binds the inner wires together, and its outer markings indicate the number of wires and size of wire (gauge) within the sheathing.
What’s the difference between white and yellow wiring?
For example, white sheathing means that the inner wires are 14-gauge and yellow sheathing indicates that they are 12-gauge. But looking deeper, the color of the wires inside of the sheathing reveals that different colored wires serve different purposes.
