Red Electrical Wires.
What does it mean when a wire is white?
If you see a white wire marked with black or red (or a piece of black or red electrical tape at its ends), that means it’s acting as a hot wire and is no longer neutral. Green wires connect to the grounding terminal in an outlet box and run to the ground bus bar in an electrical panel.
How does electrical current return to the service panel?
Once power leaves the electrical panel through the hot wire of a circuit and works through devices such as a light bulb or an outlet, the electrical current returns back to the service panel through the neutral (and usually white) wire that is connected to the neutral bus bar, which returns the current to the electric utility grid.
What color wires are used in electrical wiring?
These are the most common colors used in electrical wiring. Other color combinations, such as striped wires, may be used for other applications.
