Minimum clearance requirements for overhead power lines are meticulously defined by national and regional standards to ensure public and worker safety. These distances vary significantly based on voltage levels, the type of surface below (e.g., roads, pedestrian areas, agricultural land), and the type of structure (e.g., buildings, signs, antennas).

For example, the National Electrical Safety Code (NESC), a widely adopted standard in the United States, specifies different vertical and horizontal clearances. A 12,470-volt distribution line will have different clearance requirements over a public road compared to a residential building. A key takeaway is that higher voltage lines require greater clearance distances.

It is crucial to consult the specific local regulations, as they can differ from country to country. For instance, regulations in Europe or Australia may have different metric-based standards (e.g., 4 meters over farmland in Ireland).
