I'm setting up my entrance riser for my shop. The weather head is 13' up from the top of the panel box, and the shop "roof" is 11' from that with 2' of the 2.5" IMC conduit riser extending above the roof. The problem is, the IMC comes in 10' threaded sections so I will have the connection about 1' below the roof line. The connections are very rigid, and I will put a single brace above the connection to the wall (see picture) I cant find anywhere in code showing this other than an implication that there has to be a brace between the connection and the unsupported section. The threaded connections seem as rigid as the pipe itself.
My question is: Does this attachment meet NEC intent?
The second option which I don't like and don't have the equipment for, is to cut the lower IMC piece and re-thread it at about 8' length... For info, I am in AZ and the service will be Tucson Electric Power.
