Which outcome occurs when exceeding the interrupting rating of a circuit breaker in a high-voltage industrial power grid?

💡 Explanation

Severe arc flash and physical equipment damage result because exceeding the breaker's interrupting rating means fault current surpasses the breaker's `arc quenching` ability, leading to uncontrolled plasma discharge; therefore, catastrophic failure happens, rather than simply improving power quality metrics like voltage or harmonics.
