One other question. Will the amp draw be more at 230 volts or at 208 volts?
The FLA will be higher when running the Motor on a 208 VAC Circuit - when the Motor is developing rated Horsepower.
I was wondering if the Nameplate Ratings of the new Motor show the FLA on a 230 VAC Circuit as 3.0 Amps, and the FLA on a 208 VAC Circuit to be higher - like maybe 3.6 Amps.
If not, could it be that the Ammeters are "True RMS" type, and may be measuring harmonic currents, in addition to currents flowing within the "normal" Apparent power package (just curious..).
A 10 µF Capacitor - with like a 370 VAC rating, sounds about right for a 1/4 HP - 1/3 HP PSC Motor.
Does the Motor Start "Slowly", and Stop "Quickly"?
If yes, sounds like the shaft, or blower, is binding against something; possibly the Motor's enclosure is out of alignment.
