What is the minimum height for secondary lines over streets or alley ways?

The minimum height for secondary lines over streets or alleyways is established to ensure safety and accessibility for various types of vehicles, pedestrians, and equipment that may be navigating below the lines. A minimum height of 16 feet allows for adequate clearance for delivery trucks, emergency vehicles, and other tall transportation methods, reducing the risk of accidental contact with power lines which can pose a significant hazard.

In many jurisdictions, this height standard is established based on electrical safety regulations and infrastructure design practices. Such a height ensures that lines are safely elevated above normal vehicle and foot traffic while also considering factors like the potential for snow accumulation, which may further lower the effective height. Therefore, selecting 16 feet provides the necessary balance of safety and practicality for urban and suburban environments alike.
