We're tapping and extending from the secondary from these existing xfmrs so it's not imperative I figure it out, but I want to know why there's a 480/480 transformer. Is it because of distance (of which appears far diagrammatically via several hand holes). It doesn't appear they're using a neutral on the secondary side so not because they needed a wye... thoughts?
eta for clarity, the question is: under what circumstance would you use a transformer of the same voltage and how would one size and specify?
