Distance between distribution box and main line
There must be a minimum HORIZONTAL distance of 3 m between any part of a building and the closest medium-voltage line. Example: Adding a storey to a building near a distribution lineElectrical clearances set the minimum safe distances for panels, overhead lines, pools, and buried wiring — and ignoring them has real consequences. They would have done better to use an LB or a gutter. • The. The following table of Safe Distances from EMF Sources is offered below to help reduce your exposure to electromagnetic fields (EMFs). But the actual EMFs emitted from different sources can vary greatly, and the distances needed to reach a desired “safety level” are difficult to predict.
