Different Screw on Neutral and Ground Bar
I'm in the process of adding a 2nd AC and a new 20 amp breaker and I started working in the breaker box last night and saw something that gave me pause. The middle screw on the neutral and ground bars is different than the others. The threads of both of those screws are also painted green.
I can't find anything from the manufacturer that says those slots aren't normal connection points, but I have no idea why the screw is different. There's even a spot where two ground wires are under the same single screw instead of using the other spot, which again, gives me pause.
Any thoughts?
