I had a bathroom light that would sometimes flicker a bit when turned on. Darned back-stab connections. Anyway, ALL of the switch and outlets I examined on that circuit had the ground wire wrapped around the ground screw but the screw was not tightened. The house is around 13 or 14 years old. I bought it 1.5 years ago. Looks like I'll have to methodically go through the house checking, uh, no, tightening the ground screws. Also the outlets were daisy chained via the back-stab connector. Has that ever been allowed?
