What is the minimum vertical clearance for overhead conductors above residential properties?

The minimum vertical clearance for overhead conductors above residential properties is set to ensure safety and accessibility. In residential areas, the National Electrical Safety Code (NESC) typically requires a minimum clearance of 12 feet. This height helps prevent accidental contact between the conductors and any structures, vehicles, or individuals below. Adequate clearance is crucial to mitigate risks such as electrocution and electrical fires, particularly in locations where people might be in close proximity to the electrical lines.

The specification also takes into account various factors like potential future constructions, foliage, and changing conditions that could affect the vertical space above residential properties. While options such as 10 feet may seem adequate, they do not provide the buffer needed to address these safety concerns effectively. The clearance of 12 feet strikes a balance between safety regulations and practical considerations for maintaining electrical infrastructure above residential areas.
