I want to run some triplex low over a dome top portable canvas garage for temporary power. The garage has been there for years and will not be moved during the 40 days temp power will be used. NEC 225.19 requires 8'clearance and does not have any exceptions that apply to this situation.
Since the roof is not walkable it seems like the intention of exception #2 "where the roof has a 4/12 pitch or greater a reduction to 3'shall be permitted" should apply but it doesn't read that way. What's your opinion on this?
