Need a little help here… I am trying to install a dimmer switch in my living room. The old standard switch has 4 wires attached. 2 black, 1 white, and one copper. My new dim switch has only three wires. I am assuming that the copper wire is a ground, and the new switch doesn’t seem to have a screw for the ground. My questions is what should I do with that copper wire and to make sure that I install the switch properly!
Thanks JB
