Thanks for the input, Earl. That's what I ended up with this AM- I was just concerned about multiple paths to ground across 2 species(480, 120/240). This application is on the 5th floor, and we found a good 3" copper water riser close by. BUT the real whammy is that the facility manager who insisted, then confirmed that there was no available 208Y120 around, was wrong as we located a panel he had "checked" with 20 out of 30 spaces as spares, with CB's installed already- so...120' of emt & wire and we walk on water again(until next time)
