What is the required vertical clearance for service drops installed over a roof surface?

5 feet
6 feet
8 feet
10 feet

The correct answer is: 8 feet

The required vertical clearance for service drops installed over a roof surface is 8 feet. This standard is in place to ensure safety and accessibility. The clearance requirement helps to prevent accidental contact with the service drop lines, which can pose hazards to both individuals on the roof and those below. Maintaining an 8-foot clearance provides adequate space for persons, equipment, or objects that might be present on or near the roof, ensuring that neither the electrical installation nor normal activities are compromised. This distance also considers factors such as weather conditions, potential snow accumulation, and any objects that might be placed on the roof, all of which could reduce the effective height and increase the risk of contact with the service drop. This requirement is part of the National Electrical Code (NEC) regulations and is essential for ensuring safe and reliable electrical service while minimizing risks associated with overhead electrical conductors.
