Make a Safety Boundary Look Up Home< BackNext >


When working with ladders or long tools:
Stay at least 10 feet away from overhead power lines carrying up to 50 kV.

When cranes or derricks are used in construction:
Keep equipment 20 feet away for voltages less than 350 kV and 50 feet away for voltages greater than 350 kV. If voltage is unknown, contact Duke Energy before work begins.

As voltage increases, clearance distances also increase.
Contact Duke Energy and consult the OSHA regulations at for specific safety clearance requirements.

Clearly mark boundaries.
Use tape, signs, or barricades to keep workers and equipment the required distance away.


If you are in doubt about line voltages, clearance requirements, or how to work safely near power lines, contact Duke Energy.
