I have a basement bathroom I am fixing up and it needs some wiring improvements. Currently two boxes, one for light switch and one for gfi outlet, plus one over head light box. Black White and ground wires running from overhead to upper outlet box and another from outlet box to switch box. Then source wires ending in outlet box. Thr main constraint is the absurdly high placement for the upper box for the outlet because of short length of the power source wire in that box (I am okay with it though because it's a basement bathroom). I'd like to put a gfi there. I can't figure out how to wire it all properly. Any advice would be much appreciated. Thanks

Hello, Attached is a photograph of a subpanel in an outbuilding. I am told that it was wired by a professional electrician. I am confused because I thought a sub panel needed to have separate neutral and ground bus bars. Any thoughts on whether this has been wired correctly? Thanks for the help! [ATTACH]32841[/ATTACH]
