What is the minimum clearance required over residential property for overhead spans of conductors rated under 1,000 volts?

The minimum clearance required over residential property for overhead spans of conductors rated under 1,000 volts is 12 feet. This standard is set to ensure safety and accessibility for both the electrical conductors and the area below. The 12-foot clearance helps prevent accidental contact with the conductors by people, vehicles, or objects, significantly reducing the risk of electrical hazards.

In residential settings, maintaining a distance of 12 feet also accommodates for potential growth of vegetation and allows for safe passage of any structures that could be introduced below the overhead spans. This clearance requirement is essential for public safety and plays an important role in minimizing the chance of electrical faults due to low-hanging conductors.
