Overhead Power Lines

There are several things to remember about overhead power line safety. First and foremost is that overhead power lines are NOT insulated. They will energize anything that comes in contact with them and provides a conductive path to the ground. Utilities elevate lines on power poles to higher levels than people can normally reach. However, someone can still lift long metal devices, such as ladders, TV antennas, or other conductive objects into the lines.
It is also important to never approach, or try to move, a power line that has fallen down to the ground. In fact, keep at least 10 feet away for safety's sake. Similar rules apply to sagging lines. National codes dictate the minimum distances from the ground for power lines carrying various voltages. If you suspect that a power line is hanging down too far, let the utility know.
Guy wires are attached to some utility power poles to keep them upright. It is a good idea to stay clear of all guy wires. Even though guy wires are not electrically charged, they are in direct contact with the ground and become an easy path for an electrical current.
In short, remain clear of all overhead power lines and their supporting structures.
