I just read 2014 edition's 705.12(D)(2). Granted the Code double speak may not have set in yet, but the way I currently read it, it either fails to cover MLO panel feeder ampacity... or it is included under the Taps subsection. Whichever the case, all three subsections (Feeders, Taps, Busbars) use the sum of inverter outputs at 125% and the primary OCPD rating. So I have to ask how you see the issue as addressed???I'm quoting my own post as all seem to have ignored it. There is no engineering reason for you to size the feeder conductors as you are being asked to do by the POCO. Yes, as I said in my post #8, I recognize the 2011 NEC would require it to be so but this has been addressed in the 2014. You said the AHJ approved this as drawn (maybe they see the obvious) but the POCO says no. If this a long run that will cost money, why don't have a discussion with the POCO and show them that the NEC now recognizes the obvious.
