I recently had a contractor/handyman install a Hunter ceiling fan for me. It worked great, but my wife came home and thought it was too big. I ordered a different Hunter fan, and figured I could install the new one myself, using his wiring as a guide while also following the manual.
My experience with electrical wiring is pretty minimal, but I feel comfortable following the directions, using wire connectors, etc.
The directions call for connecting 3 wires from the ceiling box, but there appears to be only 2. The contractor connected the black ("ungrounded") ceiling wire to the black and blue wire (light and motor) of the fan. He also connencted a composite of 3 white wires ("grounded") from the ceiling to the white wire of the fan.
However, the directions also call for connecting a "grounding" wire from the ceiling (supposedly green, green/yellow, or bare copper) to a green/yellow striped wire from the fan and a green/yellow striped wire from the metal hanging bracket. The contractor connected the 2 green/yellow wires of the fan and metal hanging bracket together, but did not connect anything to the ceiling box. From what I can tell, this was not an omission, as I couldn't find any other wires coming from the box.
This surprised me. The fan worked fine like this, but I'm afraid the fan may not be adequately grounded. Or is grounding the fan to the metal bracket sufficient?
My plan was to hook it back up the way he had it, but I just want to make sure this is safe.
