120/240 Trans hooked to 277/480

[sparkyzman101]

I am wondering if would be ok to hook hook a single phase 240/480 primary and 120/240 secondary transformer to 277/480 three phase system using just two legs on the primary side? Will I get weird voltages doing this. It is for a temp hook up on some job trailers. Thanks for any info

Supply the primary with single phase 480, no neutral and you will get 120/240 out of the secondary.

Don't forget bonding the created neutral on the secondary side.
