harlie, why not put a seperate meter on the barn? copper is pretty expensive for a 200 amp feed,unless it's real short. but as roger said please contact an electrician

I can't think of a reason that you would want to put in a 200A subpanel fed from a 200A panel.
If your load in the barn is that great, chances are you would need to upgrade the service at the house.
I don't know if it's an alternative, but will the PoCo give you a separate service at the barn?

I'm guessing that Harlie has, or has his eye on, a "200A panel", and figures that he needs to supply it with a 200A supply.

Harlie, that's not necessary. Your supply needs to be sized according to the load calcs in the Code, which will almost certainly be less than 200A. It is very likely you can feed your 200A panel with a 50-100A feeder.

All panels have a "per stabb" rating on the inside of the cover. A 200a panel usually has a max of about 70a per stabb. You can't run a 200a circuit from a 200a pqnel. Check the "per stabb" rating on the panel.

Wouldn't that make the 80 - 125 amp plug on breakers useless?

Eddy I have never seen a per stab ratting as low as 70.

I have seen 100 per stab but that does not prevent larger breakers.

A 2 pole 150 amp breaker for a 200 amp panel will use two stabs per phase.
