Im working on a generater switching it from single phase to three phase we need to get 460 volts how many volts per lag do we need generater is twelve wire also should i use delta configuration or y configuration i need to run a electric motor that is 460 volts
Hello. Welcome to Just Answer.
I prefer the wye configuration, when I have a choice.
If you do choose to set it up in a wye configuration, each leg to ground or neutral should be 277 volts.
Any hot leg to either of the other two hot legs should be 480 volts.
thank you very much
