Glory Red Wire In Ceiling Light Box
When you see a red wire in a light switch box it can mean two things.
Red wire in ceiling light box. An extra red wire in the electrical box is probably an extra hot wire for a fan. Or it could be the red wire is the wire going to the fixture and the black wires are the live wires. So the red wire is probably the one you want.
When there is an extra hot wire it is red. Normally you ll see a red wire in places you would expect a ceiling fan. But in places like a bathroom or a wall light if you see a red wire it s a good bet that the red wire is the wire that s connected to the light switch.
In this case red is hot. Ground wires are either left bare or covered with green insulation. If you change a light fixture and find a red wire in the electrical box chances are the black wire from the fixture needs to go to the red wire in the box.
The red wire as a spare wire when a ceiling fan is not installed this spare red wire is insulated with electrical tape or capped off with a wire nut. The wall switch typically when a ceiling fan is installed the red wire is most commonly used for the light and the black is commonly for the fan motor. It could be there is or once was a three way switch in play.
In my friend s case the solution was simple if. Ceiling fixtures almost always have a black and white wire.
