capacitance
Even if the capacitor plates were able to survive the negative voltage for a short time the effective AC impedance of a 100uF capacitor connected to the AC mains without many other series components to limit the current would result in a goodly amount of power being dissipated in the component resulting in the sealed can expanding and exploding.

How to Hook Up a Pool Pump Capacitor Like a Pro and Avoid
Capacitors can leak over time, which can cause your motor to malfunction or fail. Inspect your capacitor regularly for any signs of leaks or bulges. If you notice any leaks, replace the capacitor immediately to prevent further damage to the motor. Test Capacitor and Motor. Test the capacitor regularly to ensure that it is functioning properly
Why Your Submersible Motor Keeps Burning: Causes and Solutions
1. Common Causes of Motor Burnouts. a) Voltage Fluctuations. One of the primary reasons for motor failure is voltage instability. If there are significant fluctuations in the high tension (HT) or low tension (LT) sides of your power line, your motor is likely to burn out. The drastic changes in voltage can overload the motor, leading to severe
DC MOTORS —Against Back-EMF. How to Prepare
