What occurs if a run capacitor remains in the circuit too long?

When a run capacitor is designed for continuous operation, it means that it can remain in the circuit during the entire runtime of the motor. This design enables the capacitor to improve the motor's efficiency by providing the necessary phase shift for optimal performance. Run capacitors are created to handle the continuous voltage and currents they experience when the motor is operational, which means they are specifically meant to function in this capacity without self-destruction or degradation.

In contrast, a start capacitor, by design, is intended for brief burst usage to get the motor up to speed and does not stay in the circuit once it reaches operating speed. Understanding these differences helps clarify that a run capacitor remaining in the circuit doesn't negatively impact its functionality, as it is inherently designed for that role. Therefore, the notion that it will degrade, self-destruct, or cause a shutdown is not applicable in this situation. The capacitor continues to work effectively as long as it is within its operational specifications and not experiencing excessive heat or voltage beyond its rated capacity.
