What about installing a 200 amp breaker in the 400 amp buss box?
We talk a lot about doing it for smaller boxes, is there a reason it won’t work here?

Or even a 400A one to allow for additional work inside (CT’s), then perform a supply side connection in it. Some manufacturers of switchgear have an option for lugs that accept multiple conductors, so no piercing of conductors needs to happen.
