There is no one way to determine a safe distance from street power lines, but a good range is between 10 to 200 feet from the wires. For high voltage transmission lines with larger cables and tall towers, a safe distance is around 700 feet.


The minimum distance when working on construction around power lines depends on the voltage of the power lines. The standard recommended distance is a 20-foot radius around the line, but the distance can range from 10 to over 45 feet depending on the voltage.


Working distance is a term used in microscopy to describe the distance between the specimen and the lens. Microscopes usually have a short working distance.


Use the online distance calculator tool on DistanceCalculator.GlobeFeed.com, FreeMapTools.com or DistanceFromTo.net to find the straight-line distance between two cities. Other names for straight-line distance include flying or air distance.


It is possible to get Internet via power lines in certain areas. As of 2014, the technology was being tested in select U.S. and UK cities.


In basketball, the three-point line is at differing lengths depending on the age and level of competition. In the National Basketball Association, the three-point line is 22 feet when measuring from the center of the rim to the sides. The top of the arc is 23 feet 9 inc...


The red balls attached to high-voltage transmission lines are aerial markers to increase the visibility of power lines for low-flying aircraft. These early warning devices reduce the risk of airplanes and helicopters colliding with thin power lines that are barely seen ...
