This is actually embarrassing that I'm asking this, but I can't seem to find the right clauses to back it up... Major brain fart day!
At an industrial site, we have a 600V, 3ph, 3w outdoor panel feeding over to a little temporary 600-120/208V transformer... there's a buried ground electrode around the 600V panel, but nothing at the temporary transformer location. We are running Teck cable (w/ bond wire) from the big panel to the little transformer and I can't for the life of me recall if we need to run a separate ground wire from the buried electrode at the panel to the little transformer Xo (as opposed to using the bond wire in the teck cable). I mean, I'm pretty sure we do, but I can't find the right backup info??
Thanks!
