@waross. Thank you. I was so hung up on trying to use the 460v that we have in the lab,that I hadn't given much consideration to the 120/208 that is also available to me. Question though: Isn't it true that open delta only gives you 57.7% of the power that a true three phase transformer would...
I teach in an electrical apprenticeship program, and focus on motor controls. Recently, we received 4 donated 330/575V (8.5/4.9A) three phase, six lead (Y or delta), 3.7Kw (European) motors for our lab. In the lab, we have a three phase 120/208 panel, and a step down 480 to 208Y/120...
