I'm having trouble getting signed off by a local building dept. The reason is that an Enhase microinverter system I installed has conduit that runs through the attic, they quote article 225.32 saying that the micros are a feeder and we need to add disco's where the conduit enters the building. I sent them a report from Enphase ( http://enphase.com/support-north-america/downloads/ ) under studies & White papers - "connectors as A/C disconnects...." that I thought would answer and I sent a copy of 690.31 (E) which, although it refers to DC circuits needing to be in metal raceways, states where the disconnect needs to be (not on the roof). They are unsure and won't approve the pv system as installed. They said they would have to get some word of authority on this as their concern is article 225.32 and their concept of a disco doesn't include "Connectors as A/C disconnects"
I could just comply and add the discos, but I feel responsible to get this building dept sorted out. We are all on the same page here in that we want safe systems etc. Plus it's a big fancy house & the discos won't look good.(the PV modules are grouped on 4 spots w/4 places that conduit enters the attic)
I don't seem to have the altitude of authority or the concise code references or explanation to satisfy them. Any suggestions?
