What is the minimum vertical clearance required for overhead electrical conductors?

The minimum vertical clearance required for overhead electrical conductors is 10 feet above finished grade. This requirement is established to ensure safety and to provide adequate space for vehicles, pedestrians, and other activities that might occur beneath the electrical lines. The 10-foot clearance helps to reduce the risk of accidental contact with the conductors, which can lead to electrical hazards, injuries, or even fatalities.

This standard is aligned with safety protocols set by the National Electrical Code (NEC) and adopted by local jurisdictions, including North Carolina. Adhering to this height helps ensure that conductors are well above common reach, especially in areas where tall vehicles like trucks may pass. The specific clearance requirement takes into account various factors such as the environment and possible obstructions, ensuring that both public safety and electrical system functionality are maintained.
