States that the system must be grounded in accordance with 647.6.
647.6(B) says the grounding bus must be connected to the grounded conductor on the line side of the separately derived system's disconnecting means.
Situation: I will have a 208V WYE Primary TO 120V Delta Secondary transformer. I was planning on "Floating" the neutral connection on the primary side since there is no need for it with a delta secondary. If I do this, how do I comply with 647.6(B) so I can properly ground the grounding bus?
