If a transformer station is not 15 feet off the ground or housed, what safety feature must be present?

• A. A fence with a locked gate
• B. A canopy over the station
• C. A warning light system
• D. No special feature required

Answer: (A)

The safety concept here is controlling access to high‑risk electrical equipment. If a transformer station isn’t elevated at least 15 feet or housed, distance or enclosure can’t be relied on to keep people away from energized parts. A fence with a locked gate provides a physical barrier that prevents unauthorized entry, greatly reducing the chance of accidental contact with live equipment. The other options don’t offer the necessary protection: a canopy doesn’t stop access to the hazard, a warning light system only indicates status and doesn’t prevent entry, and saying no special feature is required would ignore the real risk.
