How to choose a start capacitor?
Select a capacitor with a voltage rating at or above the original capacitor. If you’re using a 370 volt capacitor, a 370 or 440 volt one will work. The 440 volt unit will actually last longer. A capacitor will have a marked voltage indicating the accpetable peak voltage, not operational voltage.
Also, What is the difference between start and run capacitor?
The start capacitor creates a current to voltage lag in the separate start windings of the motor.
