What is the minimum safe distance to maintain from overhead power lines?

2025-08-10

The minimum safe distance from overhead power lines is determined by the line's voltage and the specific work being performed. There is no single universal "safe" distance, as the risk of an electric arc, or "flashover," increases with higher voltages.

  • General Rule: A common industry practice and OSHA (Occupational Safety and Health Administration) guideline for unqualified personnel and equipment is to maintain at least a 10-foot (3-meter) clearance from power lines up to 50 kV. This distance increases as the voltage goes up.

  • High Voltage: For lines with voltages above 50 kV, the required minimum clearance distance is greater. For instance, a 500 kV line may require a clearance of 25 feet (7.6 meters) or more.

It is crucial to assume all power lines are energized and dangerous. Always consult with the local utility owner/operator to confirm the line's voltage and specific safety requirements before starting any work. Our extensive range of overhead line equipment is designed with these safety standards in mind, ensuring a safe work environment for all field personnel.
