I am trying to hang a flush-mount chandelier in a bedroom to replace an old fixture, but I'm not quite sure what I'm doing with the copper ground! The "exisiting" wiring is in the below photo- the blue arrow indicates where I believe the current copper ground is being connected. I then have the current light fixture that has a copper piece that is completely loose and not attached to the light fixture at all. Where does this attach on the light fixture? There is one hole where the wires go through underneath the bracket as well. Do I need to attach it to where the copper ground from the ceiling is attached? Or can it be attached at the mounting bracket? Sorry I feel like this is such a silly question but the guy at Lowe's was not all that helpful! Thanks!
