Does anyone see a problem with installing a SINGLE PHASE transformer (480V primary 120/240V secondary) fed from a 2-pole breaker from a 3-phase panel?
No, no problem at all. In fact, how else would you do it?Does anyone see a problem with installing a SINGLE PHASE transformer (480V primary 120/240V secondary) fed from a 2-pole breaker from a 3-phase panel?

I think that what Jraef is saying is that if the primary is 1Ø, 480 volts you don't have much of a choice but to use a 2 pole breaker in the 3Ø panel.
You can use a three pole breaker but you ultimately only utilize two lines from the source.
Which is unavoidable other than to compensate by balancing any other single phase loads accordingly if possible.Very true but the OP did specifically ask about a 2 pole. I'm guessing that maybe he's concerned about an imbalance of some kind.
