What is the minimum clearance required for residential entrance cables over a driveway?

The minimum clearance required for residential entrance cables over a driveway is determined to ensure safety and accessibility. A clearance of 12 feet is established to allow for the safe passage of vehicles, including taller vehicles such as trucks and RVs. This standard helps prevent accidental contact with power lines, reducing the risk of electrical hazards.

Clearance requirements vary depending on the location and type of thoroughfare; however, for residential driveways, the 12-foot clearance accommodates most vehicle heights and provides a margin of safety. Standards such as those set by the National Electrical Code (NEC) guide these requirements, focusing on protecting both utilities and the public.

In contrast, options that specify higher clearances, such as 10' 6", 15', or 18', would exceed what is typically mandated for residential settings. Therefore, the 12-foot guideline is adequate without being overly restrictive.
