Overhead Power Line Clearances

Everyone's resources have been affected by the COVID-19 pandemic. You can help prevent locate delays by pre-marking your proposed dig area in white and notifying 811 of your planned excavation with as much lead time as possible: up to 10 business days in Pennsylvania.

Review these tips with coworkers at your tailgate or toolbox meetings before work begins to help avoid potential hazards when working near overhead lines.

The Deal on Clearances

When working with ladders or long tools: Keep yourself and all tools and equipment at least 10 feet away from overhead power lines carrying up to 50 kV.  


When cranes and derricks are used in construction: Keep the crane boom and load at least 22 feet away from lines up to 350 kV and 50 feet away from lines greater than 350 kV but at or less than 1000 kV. Always assume the line is energized, and allow nothing closer unless you have confirmed with the utility owner/operator that the line has been de-energized.


If voltage is unknown, contact Duquesne Light Company before work begins and we will send a representative out to your job site.


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


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

If you are unsure of the power line's voltage, contact Duquesne Light Company at 412-393-7100 for power line assistance or questions before work begins.

Look Up and Live
Don't Forget

Power lines are not insulated. Always consider them energized and dangerous. Any contact with overhead lines could cause serious injury to operators and ground crew.
