Which outcome occurs when ice storm loading surpasses the capacity of a three-phase distribution transformer’s pole-mounted circuit breaker?

💡 Explanation

Cascading breaker trip-out follows overload because the circuit OVERCURRENT PROTECTION trips upstream breakers progressively, therefore isolating sustained faults, rather than immediate winding failure, and affecting adjacent regions rather than localized issues.
