Yeah, after thinking a little more about it I realized that a motor that is rated for 240/208 volts will draw more current at 208 volts than it does at 240, without any change in the wiring. The tables at the end of article 430 show that.

I guess an inductive load like a motor tries to compensate for the drop in voltage to maintain power output? I'm sure this was all covered in one of my classes about 25 years ago or so [Linked Image]
