What is the minimum safe distance for a fence from energized parts when required by station height or housing?

• A. 3 feet
• B. 6 inches
• C. 10 feet
• D. 15 feet

Answer: (A)

When there’s a fence required by station height or housing, the important idea is to establish a safe buffer between energized parts and the boundary so a worker cannot easily reach or contact live equipment. The minimum distance used here is three feet. This provides a practical, achievable gap that accounts for human reach, tools, and some movement or sag in the fence, while still keeping the fence as a protective barrier around energized parts. It’s the smallest distance that still offers a meaningful separation consistent with standard safety practices. Distances like six inches are not enough to prevent contact with energized parts, and stepping up to ten or fifteen feet goes beyond the minimum for this situation, though those larger distances might be used in higher-voltage or different protection scenarios.
