What is the minimum vertical clearance required for overhead feeder conductors over residential property and driveways when the voltage is limited to 300V to ground?

10 feet
12 feet
15 feet
20 feet

The correct answer is: 12 feet

The minimum vertical clearance required for overhead feeder conductors over residential property and driveways when the voltage is limited to 300V to ground is indeed 12 feet. This requirement is set to ensure safety for pedestrians, vehicles, and structures beneath the conductors. Adequate clearance helps prevent accidental contact with the conductors during normal activities, such as driving and maintenance work around homes. The National Electrical Code (NEC) provides guidelines for these clearances, focusing on protecting people and property from electrical hazards. A clearance of 12 feet is sufficient to allow for the movement of larger vehicles and to minimize the risk from falling branches or other objects. This standard serves to establish a safe operating environment for both electrical systems and the public, aligning with best practices for electrical installation and maintenance.
