In the United States, the National Electrical Code (NEC) mandates electrical wiring color codes for the protective ground. The protective ground must be either green, green-yellow, or bare copper. âGreen-yellowâ refers to green with yellow stripes. For all other functions, there are no legal requirements.
Two three-way switches control one light with the electric power coming through the light on a two wire cable. In order to code the white wire, which is used as a power wire from the light fixture through the switches, black electrician's tape is wrapped around the wire in the boxes.he cable should also have a ground wire, or a total of four wires in the cable. The system also requires three-way switches. The switches are wider than regular single-pole switches and they have three terminal screws on the side (sometimes back) of the switch housing.
