The ceiling light/fan I want to install has a short GREEN wire. It looks ready to be twisted onto another wire. There is NO ground (bare copper or another green wire) coming out of the ceiling box. What do I attach the short green wire that came with the fan/light to?
This wire is usually connected to a bare wire ground if available, if not available and the box is metal connect it to the box. If you do not have an equipment ground the wire is not used.
Current code allows a ground to be added as long as it comes from the same panel that feeds this circuit (it can come from another circuit if grounded and fed from the same panel)
