I have read that the NEC requires EMT on the roof in a solar install to be "water tight", but also to drain. Can I run a section of EMT over the peak (up the 5/12 roof and down the other side) with no breaks, and leave the ends open (obviously with bushings to create a smooth opening and allow for bonding the EGC). This section of EMT would then be water tight (solid tube) and drained (open ends). Logically (to me that is) that would satisfy the NEC. Similarly I have another section of EMT tubes bound together with compression fittings ("water tight") and with open ends (both sloped so that they would drain).
A related question - what do people put in the openings to keep critters out?
