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.
That cable's white wire is also connected to the switch and runs back to and is connected to the light. Flipping the switch interrupts the flow of electricity, and the switch does its job. Because the white wire from the switch to the light is now a hot wire, it must be marked to show it is hot. Wrap a piece of black electrician's tape around it at both ends or color the end black with a marker to show that it carries power. With through wiring, power enters the switch box. The feed wire (the hot wire coming from the service panel) runs to the switch before it goes to the fixture. Two cables enter the switch box -- one supplying power and one going to the fixture.
