A steel pedestrian bridge over freight rail tracks in a rail freight yard. The bridge is approximately 20 feet high and has no electrical equipment mounted on it. The bridge is specifically for routing pedestrians over the freight without incident. Does NEC require a steel pedestrian bridge with no electrical equipment attached to have any type of grounding? If so, which specific NEC Article addresses this issue? Thank you.
 
I cannot imagine that the NEC would require bonding for something without any wiring on it. IMO, nothing is required but let's see what others say. BTW, I have no knowledge of this being in the NEC. Perhaps in some other codes, IDK.
 
I think 250.104(C) is your way out. All you need to do is point to the words, "likely to become energized," and note that getting energized is not only unlikely, it is impossible.

I think I covered that in my response. But what would you ground it to-- it probably is already ground to the earth

You seem to be reading things that I did not type. :D



Dennis also had already mentioned other codes. :cool:

But if there is no electrical what would you ground it too?
