New Pump Connection
(OP)
I have an Emergency Panel 480/277 V 3 Ph,4 Wire,60 HZ . It has in outgoing 3ph 4 wire breakers connected. I need to purchase a new de watering motor of 1 HP & to give power from this panel.
1. Can i connect 1 phase also from the outgoing 3 ph breakers.
2. The voltage for 1 phase is 277, so will 230 V 1 ph will be suitable.
thanks

RE: New Pump Connection
You other option will be to purchase a 480V:240V transformer and run a 230V single phase pump.
No, 277V is not quite the same as 240V. That;s why they call one 277V and the other one 240V.
Supply voltages are multiples of 120V.
Motor voltages are multiples of 115V.

Yes, the 460 V motor will be more expensive. Just deal with it.
