Understanding & Selecting Capacitors

The start capacitor is connected into the motor''s electrical circuit at rest. It gives the motor an initial "push" on start-up, briefly increasing its starting torque and allowing the motor to be cycled on and off quickly. A typical start capacitor rating ranges from 25 µF up to 1,400 µF and 110 Vac to 330 Vac.
