I just need to ask one more question as annoying as it may seem.It is a normal metal building on a concrete slab. standard construction
HOLD UP, no center taps. yes, these are the pole transformers/ POCO xfmrs. 480V 3 phase. the secondary of the pots has ONLY 2 connections. #1 is to the other 2 pots and then ground #2 is to the 3 hot wires to the mill
two individual pole transformers?
or 3 individual pole transformers?
