• B. 15 feet
• C. 18 feet
• D. 20 feet

Answer: (C)

The minimum clearance required for service drops over public areas where truck traffic is present is 18 feet. This standard is in place to ensure the safety and reliability of electrical service as well as the protection of vehicles passing underneath. The height requirement considers the size of the vehicles that may travel under the drops, including larger trucks, ensuring that there's sufficient space to prevent any accidental contact with the wires that could cause electrical outages or safety hazards. The 18-foot clearance is also in line with the National Electrical Code (NEC) and local regulations, emphasizing the importance of maintaining safe distances in areas with potential vehicular traffic. This height requirement mitigates risks associated with electrical interactions and traffic, prioritizing both electrical safety and public safety.
