Hi all,
I have a few questions on section 690.47.. a, b, and c. the 2008 NEC. Electrofelon asked these questions on a post from a few years ago, however I wasn't able to follow all the answers. Either this section is not clear, or my brain is too smooth with no wrinkles.
for part a: does this have to do with AC modules / microinverters? if so, how are microinverters grounded? is there a diagram somewhere?
for part b: what exactly is a DC system? so there's no AC output? how does this work?
for part c: i'm assuming this has to do with regular inverters with integral transformers? DC input, with an AC output?
Thanks!
