I am working on a 1 MW PV installation which got me thinking about a few things. For the purpose of this discussion, assume the NEC applies here. I was having a discussion with a coworker about a few code violations the engineer made. One was that he didnt upsize the feeder EGC's proportionate to the ungrounded conductors which had been upsized for voltage drop. The coworker said there was an exception to that rule for PV and I stated but that the feeder wasnt part of that exception. Anyway, that got me thinking about this broader question: Is there anything different about a service or feeder that contains ONLY PV generation and no loads? I say no, except for indirect consequences such as 705.12(D)(3)(c). Similarly, is there anything special about a PV line side tap? I say no its just adding another set of service entrance conductors and an additional service disconnecting means correct? I see no purpose to 230.82(6). Does anyone disagree with this?
