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)

The key idea is keeping a safe clearance from energized overhead lines to prevent electric shock or an arcing incident as the crane moves. For an 800V line, the minimum safe distance during transit is six feet. This distance accounts for potential line sag, wind, and the crane’s movement or load swing, which could reduce the actual gap and create a path for arcing if you’re closer. Staying at least six feet provides the necessary safety margin to avoid contact or arcing. If conditions could bring the line closer than that, stop and reassess—de-energize the line or adjust the setup and routing before proceeding. Distances of four feet are too close for this voltage, while eight or ten feet exceed the minimum and are not needed unless site-specific requirements call for extra clearance.
