Question

Wiring a display, help!!


I am building a display using a Cutler-Hammer panel: BR3030B150V2. It is a 150A 30/30 space/circuit panel. It has a 100A main breaker without any lugs, just the srews on the breaker itself.

I am trying to make this display as accurate as possible. I was wondering what size wire and how to wire the feed to the panel.

Thanks. Any help would be greatly appreciated.

Are you trying to show how a real panel would be wired?

Yes. It will not be energized, I just want to show how it would look if it was hooked up for real. How it is fed and a few branch circuits.

I suspect what you may have is a main lug only panel. This would be typical for a non-service panel. Service panels have a main breaker already mounted and the incoming conductors attach to them.

It is not a main lug, it is a main breaker.

Will #2 fit under the screws of the breaker?

Should I use 2/2/2/4/? Two on the breaker, one on the netruel bar and one on the ground bar.

If it is a 100a breaker it will.
