I have a 20HP, 3ph motor on my lathe. The label says it is a 220/440, but
there are only 3 wires coming out of it. I assume it was rewired straight
some time in the past. Motor appears to be 1940's model. Is there a way
to test the motor to tell if it is wired for strsight 220 or 440 ? The
controls have 440 stickers on them. So I assume the motor has been rewired
for 440. But is there a way to test for sure? thanks, McGee



Check the voltage rating on your contactors and/or what voltage
position the control transformer input is set at.

"First Law of Leftist Debate
The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
losing face the chance of him calling you a racist, bigot,
homophobe approaches infinity.

This is despite the thread you are in having not mentioned
race or sexual preference in any way that is relevant to
the subject." Grey Ghost
