William,<div><br></div><div>I have not been successful arguing that the load is integral within the array despite the fact that the DC load is clearly utilized at the microinverter. This has been a point of contention in area jurisdictions since NEC 2008 was adopted and we started installing microinverters. Maybe it's time to take another run at it, citing the elimination of the section in NEC 2011.<div>
<br></div><div>Regarding the bare CU in the attic, some local inspectors have a real issue with what is "subject to physical damage." I'd like some code citations to be ready if anyone has it handy.<br><br>

My plan was to use the new Enphase coupler to connect the trunk cable to Type TC-ER, enter a Soladeck passthrough box on the roof into a junction box in the attic where I would make the transition to 10/3 Romex. I'm hung up on the GEC going back to the service panel. Any suggestions?</div>
<div><br></div><div>By the way, we are on NEC 2008, and in most cases there is also a requirement for an additional grounding electrode per NEC 690.47(D) (that shouldn't really relate to my issue).<br><br><div>
