What is the required minimum clearance from final grade for overhead service conductors over areas accessible only to pedestrians?

The minimum clearance requirement for overhead service conductors over pedestrian-accessible areas is established to ensure safety and prevent accidental contact with electrical conductors. The appropriate clearance for overhead conductors above walkways or pedestrian areas is 10 feet. This height provides a buffer that helps protect individuals from electrical hazards and potential injury when passing underneath the conductors. It is crucial for maintaining a safe distance, especially in areas where people regularly walk or gather.

The code and regulations set these clearance standards based on safety considerations, accounting for factors such as the potential for people to reach up or raise equipment. Therefore, a clearance of 10 feet is deemed adequate and necessary for ensuring safety in areas that are exclusively for pedestrian access.
