My fan had a dual pole light switch... one for the fan, and one for the light. So the ceiling has 4 wires coming from it. One is a white ground, one a white wire, another red, and another black.

My light fixture has only 2 wires plus a ground. What do we do with the red, black and white wires?

  • Can you post a photo of the inside of the ceiling box? – ThreePhaseEel Feb 25 '17 at 20:54

Ground (bare, green or green/yellow) can only be a ground.

You need one neutral/return, and it must be a white or gray wire, so that's your white.

You need one "switched-hot" wire. Electrical code says you can use any color not already mentioned.** An often-used convention is that a switched-hot is the color other than black, i.e. red.

The remaining wire gets capped off at both ends. Put a smallish wire-nut (e.g. orange if you have it) and hold it on with a few loops of tape; as wire-nuts are prone to falling off single wires.


** outside of certain industrial installations. The general idea is that electricians should measure instead of assume.

  • Not to make things more difficult, but if you want the same setup as before, some new fans will have a cardboard or plastic shield beneath the wires which reveals a wire nut which can be removed to power the fan separately. – mreff555 Feb 25 '17 at 22:27
