What is the minimum vertical clearance of the service drop above residential property grounds?

The minimum vertical clearance of the service drop above residential property grounds is set to ensure safety and reduce the risk of electrical hazards. The correct clearance is 12 feet. This height is critical to prevent accidental contact with electrical lines, particularly in areas where people walk or work. It allows for adequate space for ladders, tree branches, and other potential hazards that could reach the wires.

Having a clearance of 12 feet also complies with the National Electrical Safety Code (NESC), which dictates safety standards for utility lines. This standard helps to prevent power outages, electrocutions, and other dangerous scenarios that could arise if the wires were positioned too low. Other clearance heights outlined in the choices would consequently increase the risk of these safety issues.
