ok, I can see the interpretation of the utility pole as being a structure, because of the "constructed " part of the definition, but I am confused on the use of 250-32. when can you use part a or part b? also, in 250-32D, if the disconnect is located remote from the building(which is the case if the disco is on the pole), the the conditions say no grounding and grounded connection, and an EGC run to the seperate structure of building. am I confusing anyone yet?( Mostly myself [Linked Image]
