Most run capacitor applications use a rating of 2.5-100 uf (microfarads) capacitance and voltages of 370 or 440 VAC. They are also usually always 50 and 60 Hz rated.

AI Customer ServiceThe capacitor size calculator is based on the concept of the start-up energy stored in a capacitor. Such energy is computed using the equation: where: V V — Voltage of a capacitor. From this previous equation, you can see that the capacitor size formula is
If you cannot get an exact size match to the original motor capacitor, it is acceptable to use a capacitor rated one step higher in µF. The substitute capacitor must be able to handle the voltage. Run capacitors typically range in micro-farads from 1.5 to 50µF. or 50 microfarads or MFDs.
The voltage range for the capacitor should be 440V min. Enter the input voltage, motor power in watts, efficiency in percentage, frequency, then press the calculate button, you get the required capacitance value.
Believe it or not, there is a simple method to figuring the correct size capacitor, without waiting on hold for the distributor's guru. Of course, you could use a multimeter that reads microfarads (uf), but this will only tell you if the existing capacitor is weak - not the correct size!
This is where the rule of +/- 10% of the rating came from, for Start Capacitors ONLY! The voltage rating should be no less than the listed amount for the motor, for central heat pumps and air-conditioners this is usually a minimum of 370VAC.
Initially single phase motor needs little rotor push to rotate the rotor at the rated RPM. Selection of right capacitor for single-phase motor is really tough, it could lead to starting the motor or not.
