Main breaker for Milbank combo panel.

[James L]

Why not? Sounds like a MLO panel and he wants to install a 200A branch. As long as there is no specific restriction listed on the thing whats the problem? Its probably a Siemens Q2200B

It would have to be reconfigured differently from how it is put together at the factory

It comes with 1+3 bridged and 5+7 bridged

It would need 1+5 and 3+7

Maybe use short pieces of #2 copper, effectively paralleling out from breaker to some Polaris taps to get back to single conductors to feed new panel.

While I agree, technically per code with an ATS you need to be able to run everything - just in case you have a strict inspector.

One more example where the NEC is just plain wrong.

It is close to the time when the NFPA will be accepting PIs to make changes for the 2026 code....looking forward to reading your PI on this issue.

No you have the wrong breaker. The correct one (pretty sure I had the right part number) is a branch breaker. The one you showed is a replacement for a factory 200A main breaker.
