Which outcome occurs when a three-phase transmission line experiences a severe short circuit, exceeding a circuit breaker's interrupting rating?

💡 Explanation

Fault escalation occurs because without sufficient interrupting capacity, the circuit breaker's arc-quenching _mechanism_ fails under overcurrent conditions. This leads to continued current flow and further damage, therefore, the fault spreads, rather than being contained, under ideal or under-rated breaker conditions.
