I will have to feel it backwards (208-570) so would I have to remove the ground from Y??
I don’t understand how a RPC is considered a delta output.
The idler motor is a 9 lead y wound motor.

Could this auto transformer be wired to a RFC as a step up or step down transformer??
"As far as we can tell".... You have a 230/240 VAC single-phase feed to an RPC and want to boost the 3-P output to 575 VAC 3-P?“
Yes, this is the case. When you say re-strap the load for the lower voltage do you mean change out the motor and controls to the lower voltage. What if the motor is flange mounted. Gets more complicated. Cheers!!
Dont mean to sidetrack this thread but I have a question related to all this. Wondering if anyone can confirm the proper procedure on how you connect the WYE center point on the secondary of an isolation transformer used with a phase converter. The X0 terminal in the attached picture. This is connected to ground to eliminate the high leg problem right? Is ground wire ok or should there be a separate neutral wire all the way to single phase panel? Or something else?
I bought my phase converter used, it came with an isolation transformer and I had an electrician friend hook it up. Its been working fine for 3-4 years but he was a little uncertain about this part, and im not sure X0 is hooked up properly or even if its connected to anything at all.
Also both my CNC's have their own transformer for high/low voltage. Since they have their own transformer anyway, does this mean I didn't really need to use the isolation transformer at all?
