thank you for your thoughts on this, i'll be looking at the calcs and job site this next week.

but from the 1-line it looks wrong that the 800a s-board that was fed with 8-350's is now going to be fed from a 225a main breaker
for the whole system and 4/0 coppers to feed 3 panels rated 300a, 300a, and 200a. how can the designer do that? [not to mention the size issue of landing them/don's question]
