solar_backfeed_breaker

Answer 'how big a solar/PV backfeed breaker can this panel take?' using the NEC 705.12(B)(2) 120% rule for a busbar supplied from opposite ends: the backfeed breaker is capped at 120% of the busbar ampacity minus the main breaker, rounded DOWN to a standard 240.6(A) size (a raw 55 A allowance is not a real breaker, so it becomes 50 A).
