Short-term, limited outages are intentionally caused to isolate circuits to clear a ______.

Explanation:
Short-term, limited outages are used to isolate a portion of the system so the abnormal condition can be cleared. When equipment faults occur, they create an abnormal current flow that protection devices are designed to detect. Protective relays and circuit breakers trip to interrupt current in the affected path, effectively isolating it from the rest of the network. By purposely causing a brief outage only in the faulted section, the fault can be cleared without knocking out power to the entire system, allowing a quick return to normal operation once the fault is isolated and verified safe. A circuit or a load refers to the parts being powered, not the unwanted condition being addressed, and a hazard is a risk, not the specific electrical condition being cleared by protection.
