So on many a commercial flat roofs, we use short lengths of rigid conduit and grounding bushings on b-line chock blocks as sleeves for PV(USE-2) wire between sub-arrays or inverters. Nothing water-tight, no heyco connector, just 'protection from damage' and such.
Can I do the same kinda thing on a residential roof with sealtight? It's a Crazy, multiple surface pitched asphalt shingle roof with multiple sub-arrays. The USE-2 doesn't need waterproofing; just protected between sub-arrays. (and supported by quickmount flashings)
Picture a 10' length of sealtight between 2 sub-arrays. With either a standard sealtight connector and a grounding bushing or an insulated throat connector w/integral lug... No junction boxes. EGC would stay continuous since ST is longer than 6'.
(not pretty... but hidden under modules anyways.) Permitted?
