What is the minimum clearance for residential service drops over driveways?

• A. 8 feet
• B. 12 feet
• C. 10 feet
• D. 18 feet

Answer: (B)

The minimum clearance for residential service drops over driveways is set at 12 feet. This standard is established to ensure both safety and accessibility. Vehicles, especially larger ones such as vans and trucks, require sufficient vertical space to pass under utility lines without risk of contact, which could lead to electrical hazards. Maintaining this height protects drivers and passengers in vehicles and allows for the safe passage of emergency and service vehicles as well. In addition to safety, having a greater clearance minimizes the chances of the utility lines being damaged by any tall vehicles or equipment that may be in transit beneath them. Following this clearance requirement also aligns with the National Electrical Code (NEC) guidelines, which set minimum standards for electrical installations to promote safety and reliability in residential electrical systems.
