Nope. Straight utility power through the switchgear, distribution panel and branch panel to the UPS. (with transformers of course).

Hint 3 - To this day I still can't believe something didn't literally blow up! But nothing did.

Hint 4 - Remember we're talking about 250MCM cable here (approximately). What characteristic does cable that big have???

Short in a utility transformer? It sounds like it is acting like a single phase system B and C sharing a leg.
