We are working on a very large exterior lighting conversation at an industrial site. Replacing 400W + 1000W HID fixtures w/ new LEDs. The problem is, the existing 40FT+ wood poles don't have an existing ground wire. To add a ground to these poles would require very expensive and complicated infrastructure upgrade and would not be approved.
Question: Is this a circumstance where the functioning/existing electrical infrastructure that does not have a ground wire can be 'grandfathered' in with the new LED lights or does it require a complete upgrade to the lighting system?
Any specific NEC code you could point us to?
