Hi all,

I'm looking to see if anyone has a drawing they could up load on the grounding and bonding requirement of my situation.

I have a 225 kva 480 to 208 transformer that I plan to hook up in reverse. The input side will be the 208 3 phase and output will be 480 3 phase. Does anyone have a detailed drawing to show these grounding and bonding requirements for the input and output side. I'm looking for equipment grounds on the primary side as well?
