    Huh? If the lighting bus qualifies for your backfeed then that's it, you're done.

      Below is an example from one jurisdiction where "For Split-Buss panels the AC interconnection must be one of the six service disconnects."

      I think they meant one of "the maximum number of" six service disconnects.

        Interesting. But that would be a 'local ammendment' that has no basis in the NEC.

          If that's what your AHJ says you have to do it, I guess, but the NEC does not say that. PV connected on the load side of an OCPD does not contribute to the six handle rule.

          Really, it doesn't even if it's on the line side, but many AHJ's don't see it that way. That's a battle I actually won with my local AHJ, with some support from some material from Mike Holt.
