The Breakdown on Clearances
Maintaining the proper clearance from overhead power lines is not only critical to a safe working environment, it's required by law. Here are some good rules of thumb:

  • If the overhead line is 50 kV or less, stay at least 10 feet away. The clearance distance is 20 feet for cranes and derricks used in construction unless you have taken OSHA-mandated safety measures.
  • Keep all equipment at least 20 feet away from lines carrying over 50 kV up to and including 350 kV.
  • For lines carrying more than 350 kV, keep a minimum distance of 50 feet.

If you are unsure of a power line’s voltage, call SCE at 1-800-611-1911 before work begins. For specific clearance requirements, visit www.dir.ca.gov/dosh.

Don’t Forget!
Power lines are not insulated. Always consider them energized and potentially dangerous.

A typical distribution line along a roadway may carry between 7 kV and 138 kV; major transmission lines carry as much as 500 kV.

Any contact with overhead power lines—even service drop wires—can cause serious injury.
