Hello, first time writing in but I have been in the industry for 12+ years and I have a question revolving around NEC 705.12 of the 2014 code. If I am trying to interconnect a PV system into a sub-panel rated at 100A and my over current protection for my PV is sized at 50A I am reducing the breaker feeding that sub-panel from a 90A to a 70A to give me the allowable interconnection at that sub-panel. my question is do I still need to do these calculations back at the main panel that feed this sub panel? if so I will need to do a load side meter tap. System is 35 Enphase-S280 @ 1.13A each.
