For proper safety, what is the minimum height for electrical service conductors over sidewalks?

The minimum height requirement for electrical service conductors over sidewalks is specified to prevent accidental contact and enhance safety for individuals using those walkways. Service conductors need to be adequately elevated to ensure that there is no risk of people making contact with them, especially in areas where pedestrian traffic is common.

Requiring a height of 12 feet above sidewalks establishes a significant clearance, providing a safety buffer that minimizes the risk of electrocution or injury. This height is particularly important in ensuring that taller individuals and objects, such as ladders, do not inadvertently come into contact with the conductors. In contrast, lower heights may not offer enough clearance and could lead to safety hazards.

Other options suggest heights that either do not meet the safety standards or could increase the risk of accidents, thereby reinforcing the necessity for the 12-foot requirement. By adhering to this standard, compliance with safety codes and regulations is maintained, ensuring a safer environment for pedestrian activities.
