North American and international cable have different conductor color codes. Marking of the conductors within the cable defines which conductor is ground, neutral, and line. For North American 3-wire cable, there are two color codes that are accepted and most widely used. The combination of green (ground), white (neutral) and black (line) is the North American cable color code. The international color code combination of green/yellow (ground), light blue (neutral), and brown (line) is also an accepted color code for North American 3-wire cable.
