Run Capacitor Selection Guide
Voltage: 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 capacitor will work, though the 440 volt unit will actually last longer. A run capacitor will have a marked voltage indicating peak voltage acceptable - not operational voltage.
