Overhead electrical service should be a MINIMUM of how many feet above a flat roof subject to foot traffic?

The minimum requirement for overhead electrical service above a flat roof that is subject to foot traffic is ten feet. This standard ensures that there is ample clearance to avoid accidental contact with the electrical lines. It is particularly important in areas where individuals may be walking or working on the roof, as the risk of injury or electrical hazards increases significantly if there is insufficient height. The ten-foot distance offers a safety buffer that helps to prevent electrical lines from being disturbed or compromised by routine roof maintenance or repairs.

While other heights such as four, six, or eight feet may seem reasonable for less trafficked areas, they do not provide the necessary safety margin needed for roofs with pedestrian activity. Adhering to these code requirements not only enhances safety but also aligns with electrical codes that dictate safe practices in building design and maintenance.
