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?

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.

No penetrox on your main lugs

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.
I also use it every time
