Wires don’t have different colors without reason: they have them to communicate something about their functions. If you have an electrical problem and wonder what do electricians in my area need me to be able to tell them about this problem, then learn what the different electrical wire colors mean to help out.
Electrical Wire Colors
Here are the meanings of the most common wire colors:
- Black wires provide power to switches and outlets. They also link switches and electrical loads.
- White and gray wires attach to a conductive piece of metal in an electrical panel.
- Red wires connect smoke detectors to power and in ceiling fan installations. They also link switches with electrical loads. In 220-volt circuits, they are secondary live wires.
- Green wires are ground wires. In electric panels, they run to the ground bus bar and connect to grounding terminals in outlet strongboxes.
- Blue wires serve as travelers in 3- and 4-way switches.
- Yellow wires frequently link electrical loads and switches to structural lighting, outlets that are joined with light switches, and ceiling fans.
- Bare copper wires also serve as ground wires.
Never mess with wires or other electrical equipment. Also, under no circumstances should you try to repair any wiring or electrical equipment yourself. Doing so can lead to injury, perhaps even serious injury or death. You should also never assume that any electrical wire is safe to touch. Always call a professional electrician for help if you have an electrical problem.
