Good point Ross. The panel is marked as a 200A with no indication that the bus has a higher rating, so I've assumed 200A. I considered downsizing the MB, but it's an discontinued panel, and filled to capacity so not exactly ideal.

If I missed this question, please forgive me. But, in your original post you refer to a 200 amp service. I don't, though, see mention of the rating of the bus bars. The bus bars may be rated for something more than 200 amps, depending upon the panel, even if they're protected by a 200 amp main disconnect. If so, that would increase your backfeed breaker sizing options. Best wishes, Ross Taylor
