During transit, the minimum safe distance to an 800V line is which?

• A. 4 feet
• B. 6 feet
• C. 8 feet
• D. 10 feet

Answer: (B)

Maintaining a safe clearance from energized overhead lines is essential to prevent electric shock and arcing when equipment is moving. For an 800V line, the minimum safe distance during transit is six feet. This gap provides a margin for line sway, equipment movement, and environmental factors like wind or wet surfaces—conditions that can bring parts closer together or allow an arc to jump a small gap. The aim is to keep the path of travel well clear so a spark or contact cannot occur as you move the crane or other equipment. If conditions worsen, or if the line voltage is higher, increase the distance accordingly and follow site rules or utility guidelines. Always treat overhead lines as live, use a spotter to maintain the clearance, and plan the route to avoid lines; if you cannot maintain the required distance, halt transit and coordinate with the utility to achieve a safe working clearance.
