What is the minimum overhead clearance for open conductors above finished grade or a sidewalk?

The minimum overhead clearance required for open conductors above finished grade or a sidewalk is indeed 10 feet. This requirement is crucial for ensuring safety in areas where people may pass underneath overhead electrical conductors. The 10-foot clearance prevents accidental contact or entanglement with the conductors, which could lead to serious injuries or electrical hazards.

Additionally, maintaining this height allows for adequate space for large vehicles, equipment, or future construction activities that may occur in proximity to the conductors. Compliance with this standard is necessary to minimize risk not only to pedestrians but to maintenance personnel who may work in the vicinity of these power lines.

The specific height requirement fits within national and local electrical codes, which emphasize the importance of safety in electrical installations, particularly in public areas. Overall, adhering to this clearance is vital for both safety and regulatory compliance.
