I have a job with .65A 460V 3Ph motors. The customer has 575 3Ph. I was told to use two 575 1Ph to 460 1Ph transformers to change over from 575/3 to 460/3.

That just seems really odd to me. How would you connect four leads to make 3 phases and how would that affect the leads that are doubled up.

I am brain dead right now, I have finished 30 production drawings in four days and every time I try to concentrate on this problem all I hear is static from my synapses mis-firing.

I would appreciate anyones expertise on this setup.
