3 phase in australia is 415 volts I agree between neutral and any phase its 240 volts.
How do you get any torque? even in a TT motor? hmm maybe I have missed something here. Machine tools in Aus are all 4 wire input as well, to comply with MEN system ( Main Earth Neutral) ( regardles of weather its Wye or Delta wound). Is there a text I can read regarding your comments ?
