Per Subpart K, deenergized equipment must be rendered inoperative and what else?

• A. Tagged at all points where energized
• B. Reconnected after maintenance
• C. Grounded
• D. Tested for continuity

Answer: (A)

When you work on electrical equipment, you must isolate it from all energy sources and clearly indicate that work is in progress. The key safety step is tagging every point where energized energy could be applied. This tag warns others not to restore power and provides who is responsible and when the energy was isolated. By placing tags at all control points—every switch, disconnect, breaker, or other energy source—you close off all potential paths back to a live state, so there’s no confusion about whether any part could still energize the equipment. Grounding, while important in other contexts, isn’t the requirement here, and reconnecting after maintenance or testing for continuity are actions that occur after the equipment has been safely isolated and tagged.
