Sep 30, 2017· Workers look to the Occupational Safety and Health Administration (OSHA) to understand how close they should be to power lines. As a general rule, 10 feet is the minimum safe working distance from power lines. To follow exact regulations, you should know the voltage of the power lines that you will be working near.

23-09-2019· So, although scientists don't yet understand it, the research does seem to suggest that living near high voltage powerlines is indeed dangerous. Now, as you probably gathered from reading this, how dangerous living near a power line depends entirely on the distance between you and the power line

You're probably dealing with a distribution line. Overhead distribution lines consist of wires that are supported by utility poles about 10 m (30 ft.) high. These poles are most often made of wood but are sometimes concrete. The wires at the top of the poles are medium-voltage conductors, which carry 750
