I thought I would pose this question to you all and see if anyone had encountered this situation.

We have a client that would like his emergency generator to be placed 60 feet away from the property and have it feed the building via an overhead line. The problem I am running into is that the generator is also feeding a fire pump located in the building.
I've looked in NFPA 20, NEC 700 and 695...None of the articles tell me that this can or cannot be done. Am I overlooking something that should I be looking at? :-?
 
According to Annex A (6-3) of NFPA 20: "A completely underground circuit from the generating station to the pump room is strongly recommended and should be obtained where practicable. Where such construction is not available, an overhead circuit is allowed, but that part of the circuit adjacent to the plant served by the fire pump or to the exposing plants with special reference to damage in case of fire."

Considering NFPA 70: "They shall be protected to resist potential damage by fire, structural failure, or operational accident." That may be a tough nut to crack on a overhead circuit. Particularly if the exterior wall has unprotected openings.
 
Thanks guys, I saw the part about protecting it from damage, but the annex part is what I was looking for, appreciate it!!

he thinks it'll be cheaper to do it overhead....
