I'm working on a Data Center and I have 10 susbstaions (13.2Kv-480/277V) and all rated at 5000A each. I'm installing a ground bar for each substaion because they all located in different room. I'm planning on bonding the grounding bar for one substaion to the water pipe, building steel, uffer and ground ring. Also, I'm running 3/0 insulated wire between all ground bars to minimize the potential.
1. Do I need to tie every ground bar to the main water pipe? I only did it once to the substaion closer to the water main. also I'm bonding every ground bar to the nearest building steel.
2. Do I need to tie every ground bar to the ground ring?
3. Is there any thoughts on better grounding for this system?
Thanks all in advance,
