We are installing a new 135V.DC 600Amp ungrounded distribution panel and am trying to size the equipment ground for the panel. I have not been able to find any guidelines in the NEC for this application. Our ground grid is 4/0 cu. Should we go with the NEC grounding requirements for an A.C. panel (this would be #1 cu.) ?
