Scott,
Thanks for your reply, I can't find a schematic on this setup anywhere.
This is my concern, if both systems are SDS should there be a common grounding point.
Or should both systems be electricly connected somewhere. I guess the point I am trying to make is if the "system"(4160) is grounded at one point and that being the reference, if you install ground rods at each other system, wouldn't there be a ground loop problem?
I have a hard time explaining things so bear with me here.
What I am looking for is a schematic showing how to effectively bond all systems, from the 4160 out of the substation, to the 4160X480 transformer, to the 4160x208 "pods", to the grounding electrodes, and finally to the building steel itself.(and the fences around them)
The reason I am looking for this is the building has what I suspect is a grounding problem, but with all these different "systems" involved, and my inexperience with multiple setups, I don't know how it is done or where to look.
I hope I don't sound like a bonehead here.
Can you help?
