What is the minimum vertical clearance for service drop conductors above a pedestrian sidewalk?

The minimum vertical clearance for service drop conductors above a pedestrian sidewalk is established at 10 feet. This height requirement is in place to ensure safety for pedestrians, allowing adequate space for people to walk under the conductors without risk of contact. It accounts for various factors, including the potential movement of items such as ladder trucks or the possibility of objects being dropped from elevated locations.

Maintaining this clearance helps to prevent accidents and ensures compliance with safety codes and regulations. Additionally, this standard height can accommodate different types of pedestrian traffic, including those who may be using carts or equipment that extends vertically. The other options represent heights that do not meet the established codes for pedestrian safety, making them unsuitable in this context.
