hey folks. A little update. After moving the start capacitor to the line side and making it so the the start capacitor engages before the contactor, the motor finally turned instead of locking up. Now that it was finally turning, the motor did not come up to speed. I added another 200 mfd start capacitor and this did not help either. I checked my voltage on the line side and the load side on start up and found the voltage droppping down to 175v. I am using 10 awg wire from a 60 amp breaker for approximately 6’. According to the voltage drop calculator I should be just fine, as it is only loading about .17% of the volts. Not being sure if upsizing the wire would work I hooked a 5 hp 3 phase motor and it ran perfect. I balanced the three lines and my Lathe is finally up and running. But, it still bothers me that the 10hp will not come up to speed. Do you think if I upsize the conductors to say, 8awg it will make a difference?
Thanks,
