A 75KVA Delta/Y transformer requires a #2 System Bonding Jumper.
If using a Grounding Electrode grounding/bonding connector (Kenny Clamp) on the electrode at the transformer housing is a System Bonding Jumper still required by the NEC? The GEC and the SBJ are the same size. I know it works but can it be supported in the Code? No deductive reasoning, straight forward reference to the Code.
Just curious. Trying to find an offset to the added cost. I understand the fault current discussions, I'm interested in the SBJ question.
Any thoughts would be greatly appreciated. Thank you.
