[COLOR=rgba(0, 0, 0, 0.75)]Solar PV Electrical Code question:In both NEC 2014 and 2017, 690.31(G) says that when entering a building, all PV DC conductors need to be in metal raceway to the first "Readily Accessible Disconnecting means". We also have our rapid shutdown requirements, 690.12, which can be met with Optimizers. If we are using Optimizers to meet the requirement for rapid shutdown, would they also count as a disconnect means for the purposes of 690.31(G)? Of course the prudent answer (and strict code interpretation) is probably no, but I would be very interested in hearing some perspectives on this one. Should this be updated for NEC 2020 for clarity? What would be the real life safety scenarios that would make 690.31(G) relevant when rapid shutdown is employed?[/COLOR]
