Multiple Choice

After a fault occurs, operators re-establish service by routing current to circuits that are not ______.

Explanation:
After a fault, the goal is to restore service by energizing only healthy, unfaulted paths. Operators isolate the faulted section and use switching to transfer load to circuits that are not faulted, so the restored feeders can carry load safely without reigniting the fault. A faulted circuit should not be re-energized because the existing fault would cause protection to trip again. An operable circuit might still harbor a fault or be constrained by protection settings, and an online circuit simply means it’s energized, not guaranteed to be fault-free.
