Hello Xchange Members,
I work in residential solar. When DC conductors are run on the roof between solar arrays, the conductors are usually routed in EMT. Does the NEC allow for other types of conduit (like PVC) or raceways when placed on a sloped roof and exposed to the elements? What code articles are applied in this example?
Is anyone aware of any listed products in use for this application other than EMT or equivalent?
Thank you so much for considering these questions!
