Which risk dramatically increases when capacitor bank switching causes repeated overcurrents?

💡 Explanation

Repeated overcurrents generated during capacitor bank energization subject the circuit breakers to excessive thermal and mechanical stress; because the *electromagnetic force* increases, breakers will experience contact welding. Therefore breaker damage accelerates there rather than other electrical system components that tolerate short bursts.
