________ switching is for maintenance, construction, cleaning, testing, etc.

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

Answer: (A)

The main idea is that switching actions are categorized by purpose, and for planned work you use routine switching. This is the set of actions done on a scheduled, controlled basis to prepare equipment for maintenance, construction, cleaning, testing, and similar tasks. It means de-energizing the equipment in a safe, verified state, applying locking or tagging to prevent inadvertent re-energization, and ensuring the system remains in that safe configuration while work is performed. Only after the work is finished is the equipment re-energized following proper procedures to restore service.

This differs from emergency switching, which is used to restore service or clear faults after an outage or incident; automatic switching, which occurs as part of protection or control systems without manual intervention; and protective switching, which is designed to isolate equipment to protect people and assets during abnormal conditions. Routine switching is the planned, controlled method used specifically for maintenance-related activities.
