Hi all,
First post here.. cheers. My question is involving detached garages and disconnects on the detached structure. If say we have an array on both a residential house and a detached garage and use a trench to combine the two systems to a single interconnection point, do we need to have disconnect on the garage to protect it?
More specifically, I'm thinking of Enphase systems (which is what we use)
If there is 1 branch circuit of enphase micros on the garage roof and we run a trench back to a combiner box on the house, do we need to provide a disconnect on the garage per the NEC?
I'm struggling finding anything. I know of the rules for detached garages vaguely.. which I believe is if the garage is fed from a single circuit that there are OCPDs required. Also, I believe that if a garage has a sub-panel with more than 6 throws of the hand then there needs to be a main, otherwise its compliant.
Can anyone help me out?
Thank you.
