I'm a mechanical engineer. We need water lines run to the opposite side of our production facility. The best route above the floor runs near a 460 volt bus duct.
Is it permissible to run propex type water lines near a high voltage bus duct?
What is the code/standards regarding this situation?

Thanks,

JEFF

NEC adresses foreign piping above panels and switch gear. I have never come across any same prohibitions regarding bus duct. I also am not familiar with propex, but I assume maybe it is pex of some form. If so, and if rats or squirrels are issued access cards and badges to the facility, I would give it some extra thought.

How close is "near"? What's the pressure on the line? I doubt you have an issue but it's impossible to say without the details
