Thanks for the clarification and much more detailed explanation. I was aware of the split-phase nuance and have been hit by 277 a couple of not-so-fun times.

Thanks for the clarification and much more detailed explanation. I was aware of the split-phase nuance and have been hit by 277 a couple of not-so-fun times. As to the benefit to motors, it was my understanding that using split-phase or a single phase and a capacitor creates a less-than-optimal magnetic field which results in more noise/vibration and wear on the motor as opposed to 3 phase.
