Can a Bad Capacitor Trip a Breaker?
The capacitance has dropped significantly below its rated value – A reduction in capacitance will reduce the impedance of the system or circuit as compared with when it was new. This can cause too much current flow through some components, leading to increased temperatures that could trip the breaker if left unchecked.
