Transformers

[NissanTitan08]

I have a 480v 3p primary delta primary, 120/240 secondary Y transformer. Why am I only getting one leg working in the panel.

What are the symptoms? Just saying it doesn't work is not enough information for us to help you.

No you don't.
You have either a delta-wye of 480-208Y/120 3PH 4w, a delta-wye of 480-240Y/136 3PH 4W, or a delta-delta of 480-240/120 3PH 4W.

What 10 voltages are you getting?
