What is the minimum vertical clearance for overhead service conductors over residential properties and driveways when the voltage does not exceed 300 volts?

The correct answer is based on the National Electrical Code (NEC) requirements regarding overhead service conductors. For residential properties and driveways, when dealing with conductors that do not exceed a voltage of 300 volts, the NEC specifies that the minimum vertical clearance must be 12 feet. This clearance is crucial to ensure safety and prevent accidental contact with the overhead conductors by vehicles or individuals, thereby reducing the risk of electrical hazards.

In residential settings, this requirement is particularly relevant as it aligns with safety standards meant to protect both property and public safety. The elevation of 12 feet above driveways allows for various types of vehicles, including larger ones like trucks and vans, to pass without the risk of hitting the overhead lines. It's essential to adhere to these standards to comply with code regulations and maintain safety in electrical installations.
