What is the minimum overhead clearance for service drop conductors over residential property and driveways not subject to truck traffic where the voltage does not exceed 300V?

The minimum overhead clearance for service drop conductors over residential property and driveways not subject to truck traffic, where the voltage does not exceed 300V, is established to ensure safety and accessibility. The correct clearance of 12 feet helps prevent accidental contact by individuals or objects, minimizing risks of shock or disruption in service.

This height is in line with the requirements specified in the National Electrical Code (NEC), which dictates that clearances must be sufficient to accommodate typical residential activities and prevent issues from potential obstructions. The specified distance also accommodates items such as ladders or other maintenance equipment that may be extended vertically in residential settings.

In contrast, options that suggest a clearance of 10 feet, 15 feet, or 18 feet exceed or do not meet the standard set for this specific scenario. A 10-foot clearance may be insufficient, while 15 feet and 18 feet would apply to different conditions, such as areas with higher traffic or specific commercial settings. Understanding these regulations helps ensure compliance and enhances safety in residential electrical installations.
