Overhead service conductors require a minimum vertical clearance of how many feet over residential property where voltage does not exceed 300 volts-to-ground?

The requirement for overhead service conductors to maintain a minimum vertical clearance of 12 feet over residential property applies when the voltage does not exceed 300 volts to ground. This clearance is established to ensure safety and prevent accidental contact with electrical conductors, which can be hazardous to individuals and property.

The 12-foot clearance provides ample space for typical activities that occur in residential areas, such as the operation of vehicles, outdoor equipment, and construction activities. Adequate clearance minimizes the risk of electrical shock and ensures compliance with electrical safety codes and regulations that govern overhead installations. This specification is crucial for maintaining safety standards in residential environments, where it is important to balance accessibility for everyday activities with the necessary precautions against electrical hazards.
