I am in the process of changing my vanity light. I have taken the old fixture off and have a black, white and copper wire coming out from the wall. My new light has the same (black, white and copper) There is also a ground screw on the fixture. My question is this. I know I need to pigtail and wire nut each wire. When I pigtail the two copper (ground) wires do I have to use the ground screw as well or can I ignore it?
Thanks, so what's the best way to do it. Do I wrap the fixture's copper wire around the ground screw and tighten and then pigtail and wirenut the remaining portion with the copper wire coming out of the wall?
If the ground wire from the fixture is bare and long enough then you can wrap the middle around the ground screw and wire nut the free end to the ground wire in the box. (Or if the ground wire accompanying the power feed into the box is long enough you can wrap the middle ...)
In this situation, extra lengths of wire (pigtails) are not needed unless the existing wires don't reach.
Tornado victims: Do not rush to rebuild. Take your time and look for and get a good contractor. Or consider selling the property and moving to a home that is ready to live in.
