Most overhead power lines are made of either copper or highly conductive aluminum with a steel core – and they are NOT covered with an insulating material. If you look up at a utility pole or tower, you may not be able to identify which lines are communication cables and which are energized wires. You should assume that any wire on a utility pole or tower is energized and dangerous, and stay far away. All downed wires should also be considered energized and dangerous, so stay far away from them as well and call 911 immediately.

Some power lines may appear insulated, but the coating that covers them is meant to protect the line from the elements – it does not protect people from electrical contact. Any contact with overhead lines could cause serious injury or even death.

Keep yourself, your tools and all equipment at least 10 feet away from overhead power lines carrying 50 kV or less. Higher-voltage lines require greater working distances. Contact Duke Energy in your state to confirm power line voltages and distance requirements for your job site.
