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

I thought I was going to have to leave this question overnight. I was just going to go to bed, but you guys are sooooo close I'll hang out for at least another 30 minutes hoping someone gets it.

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???

Has someone tied two of the lines to a piece of equipment instead of using earth.

Sorry, I forget my vector maths.

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

Aw man I left too long...
Now I'm thinking yes, B&C fused together... due to heat.
