We are stuck with the AHJ on a completed PV install. Everyone is having a different interpretation of NEC 705.12 #2 The question is, the size of breaker that should go in the 200A main service panel. There are 3 PV AC circuits off the roof into a combiner box where each of the 3 AC circuits land on a 20A DP breaker. So we have 39 amps to terminate in the 200A panel. One interpretations is that based on the 120% rule the max size breaker would be a 40A. Is the 40A the max to go in the 200A panel? We need at at least a 60A.
