Power lines from big metal towers emit the highest voltage creating the strongest magnetic fields. The safe distance from these power lines would be at least 700 feet. If you are using a gaussmeter, make sure that the reading shows 0.5 milligauss or less. Is living near high tension wires dangerous Power Lines Over Streets and Roadways With Commercial Traffic For any driveways, alleys, roads, or streets likely to carry vehicles more than 8 feet in height, the guideline is for all power lines to be at least 18 feet above the ground measured at their lowest point. Wires Above Pools, Hot Tubs, and Pond *According to 1926.1409, for power lines over 350 to 1,000 kV, the minimum distance is presumed to be 50 feet. Over 1,000 kV, the utility/owner or a registered engineer must establish it. Cranes cannot be assembled/disassembled below an energized power line or within the Table A clearances from a power line You must avoid any machinery, people or equipment coming within the 'safe distances'. As set out in the Electrical Code of Practice for Electrical Safe Distances , this is within 4 m of overhead power lines. For overhead transmission lines, the recommendation is to allow a distance of 6 m
Approach distances are one way of separating people from hazards. An approach distance is the minimum space from an energised overhead electric line that should be maintained by a person or an object held by or in contact with that person. The approach distances in specified zones should consider different levels of technical knowledge and items of plant The need for design guidelines National Grid is the electricity transmission business in England and Wales.
