__________ switching performed by Operators is usually in response to power outages and abnormal conditions such as overloads.

• A. Routine
• B. Emergency
• C. Automatic
• D. Protective

Answer: (B)

Emergency switching is the actions Operators take in response to outages or abnormal conditions, such as overloads, to restore service or safely isolate issues. This type of switching is about a real-time, manual response to keep the system stable when something has gone wrong, which fits the scenario of an outage or overcurrent event. Routine switching is planned work, done on the schedule for maintenance or routine reconfiguration, not in reaction to an outage. Automatic switching happens through protective devices and relays without operator intervention, immediately reconfiguring circuits as faults occur or loads need rebalancing. Protective switching involves actions taken to isolate faults to protect equipment, typically driven by protection schemes rather than operator-initiated responses. So the action described—operators reacting to outages and abnormal conditions with intentional switching—best matches emergency switching.
