Ground / Neutral Bar Question


Hi All,

I just had a Square D QO box / breakers installed. I see that the electrician connected some neutral wires to the ground bar and some ground wires to the neutral bar. Is this normal?

Ground / Neutral Bar Question


This is a main panel. There is no neutral and ground bars. They both serve both functions.

If one were added to the panel then that would only be for grounds.

FYI. While I use anti-oxidant on all aluminum connections, it is NOT required unless the equipment manufacturer or the wire manufacturer requires it. Square D does not require it's use.

He dipped all 3 feeds into his noalox bottle. If you zoom in, you can see a dark gray substance I made sure he used it.
