Paul et al,
A little off topic but I'm having trouble getting an answer to an electrical question I have and hope you or a member could help.
I bought a surface grinder that runs 480v 3 phase. I have 220v 3 phase from an inverter. I have a  lead on a 480v 3 phase to 208v Y 3 phase step down transformer. My question is can I run this transformer backwards and is the 208 Y close enough to the 220v I have  ?

Thanks,
John Rogi

That is a subject I know nothing about.
