We just installed the unit on 5-1-14. The rotary phase converter works great, very quiet, very straight forward hook up. We are powering a crane with (3) different motors.
I installed another manufacturers rotary phase converter on a different project a week before ( the customer purchased his own, thought he was getting a bargain) It took me about an hour more to hook up his than it did yours, the noise level when running is louder, finished product not as clean looking. This was for an irrigation pivot.
The rotary phase converter I purchased from you was easy to wire, noise level when running is minimal, the overall finished project looks very good. I will definitely purchase from you in the future.
