Run Capacitor Selection Guide

Start vs. Run Capacitors. Start capacitors give a large capacitance value necessary for motor starting for a very short (seconds long) period of time. They are only intermittent duty and will fail catastrophically if energized too long. Run capacitors are used for continuous voltage and current control to a motor''s windings and are therefore continuous duty.
