I have a building that is grounded with a ring around the building.
I am placing a large area of equipment across a concrete parking lot type area. That equipment will have a ground ring around it as well. My interpretation of the code is that these rings must be connected together (bonded?). I believe this conductor would be considered a Grounding Electrode Conductor. The client is against cutting the parking lot to install an underground bare conductor for this purpose. They are suggesting running along the overhead pipe bridge to go from the building to the equipment area's ring.
My questions are:
Is my interpenetration of the code correct, and these 2 rings must be connected together?
If so, can this conductor be run overhead, stubbing up from one ring, going overhead t the other ring, and then stubbing down to that ring?
Thanks,
Dave
