I have an old main panel that went in in 1971. (Square D.)
All of the circuits going out are run in conduit, and I believe grounded through it to the chassis of the panel.
I want to replace/alter many of the circuits in this panel. I also will be adding a 40A Subpanel run. Should I run the grounds from any new NM wiring into the same bus as the neutrals, or should I add a ground bus bar?

Also, my subpanel that I will be installing is a 125A Main Lug panel. It did not come w/ a ground bus installed. Is that typical? Where can I get one? Any big box store, or do I need to go to an electrical supply place? (I bought the panel from a big box store. It's a Cutler-Hammer)
