Mike,
I have a question concerning the proper procedure for grounding computer room PDU's (Load center, or Power distribution unit). Keeping in mind that the PDU's have a transformer housed within the unit. Voltages are 480volt 3phase
to primary of transformer. Secondary of transfomer is 208/120 volts 3 phase
four wire. I have reviewed NEC section 645-15 and need interpretation as to the meaning of that section.
Thank You.
