What is the minimum clearance from the bottom of a pole-mounted 240-V transformer to the ground?

• A. 14 Feet
• B. 10 Feet
• C. No Minimum Required
• D. 8 Feet

Answer: (D)

The main idea is providing a safe vertical buffer so people and equipment can’t easily contact energized parts. For a pole-mounted 240-V transformer, the minimum bottom-to-ground clearance is eight feet. This height keeps the transformer out of reach of most pedestrians and maintenance gear, while still allowing access for service trucks and ladders. It also takes into account ground variations, snow, and weather. Higher clearances aren’t required for this voltage and would just add unnecessary height, whereas no minimum would create a safety risk by allowing contact with live parts.
