What is the minimum clearance required above flat roofs for overhead service drops?

The minimum clearance required above flat roofs for overhead service drops is 8 feet. This requirement is established to ensure safety and accessibility. Maintaining this specific height prevents accidental contact with the service drop lines, which can carry significant electrical voltage. By specifying 8 feet, it accommodates various conditions, including maintenance work on the roof and helps to avoid potential hazards from falling objects or personnel working near the lines.

This clearance standard also allows for proper drainage and prevents water pooling around the service drop, which could lead to electrical hazards. Electrical codes, such as the National Electrical Code (NEC), emphasize the importance of these safety measures to protect both individuals and property.

In essence, this requirement is crucial for ensuring a safe environment around overhead electrical wiring, particularly in areas where maintenance and other activities may occur on flat roofs.
