What is the standard clearance for electric service lines over roads and public spaces?

The standard clearance for electric service lines over roads and public spaces is 18 feet. This requirement is put in place primarily for safety reasons, ensuring that vehicles, including trucks with tall loads, can pass beneath without risk of contact with the power lines. This standard helps prevent accidents and outages that could occur if lines were too low and came into contact with vehicles, especially in areas with heavy traffic or where larger vehicles are common.

The height requirement reflects both practical considerations and regulatory standards set forth by organizations such as the National Electrical Safety Code (NESC). When establishing such clearances, authorities take into account various factors, including the type of road, traffic conditions, and the size of vehicles using the roadway. Adhering to these standards is essential for the safe operation of electric service and the protection of the general public.
