Hi,
I am looking at supplying a single phase 240x480 to 120/240 15kva transformer from an existing 3 pole breaker in a 3P 3W 480 panel board (ultimate upstream source is a grounded 480Y transformer) using only 2 phase wires with no neutral. The question I have is, does the code prevent me from doing this? I've been looking at section 250 and do not see where it would preclude doing this. What seems odd is that this new transformer will not have a neutral/grounded conductor on the high side (the low side would). Am I missing anything here?
Thanks,
Bohdan
