What is the minimum vertical clearance required for service drops installed over roofs?

6 ft
8 ft
10 ft
12 ft

The correct answer is: 8 ft

The minimum vertical clearance required for service drops installed over roofs is 8 feet. This requirement is established to ensure safety and accessibility for maintenance as well as to prevent any potential hazards that could arise from lower cables. The National Electrical Code (NEC) specifies this clearance to ensure that there is adequate space between the roof surface and the electrical conductors, reducing the risk of accidental contact by personnel, equipment, or debris. Maintaining this vertical distance is crucial, especially in areas where maintenance work is conducted on the roof. If the clearance is insufficient, it may lead to electrical hazards, particularly if someone inadvertently comes into contact with the conductors while on the roof. The 8-foot requirement reflects a balance between safety and practical installation needs, ensuring that service drops can function effectively while safeguarding individuals accessing the roof. The other options suggest clearances that exceed what is mandated. While higher clearances may provide additional safety in specific situations, the code has determined that 8 feet is the minimum necessary standard to protect both people and property effectively in typical scenarios.
