We have just installed 3 new pad mount 12470 Delta / 480 Wye transformers. We have no neutral load, it's all 3 phase motors. I have a ground grid we just installed, how should that tie into my transformer and should anything be tied to the neutral bar in the low side of my transformer? Right now it goes to the ground spot on the transformer and then to the first disconnect, but it seems like there is no way for any fault current to get back to the transformer.
