What is the minimum height for outdoor service conductors to ensure safety?

• A. 8 feet above ground
• B. 10 feet above ground
• C. 12 feet above ground
• D. 14 feet above ground

Answer: (C)

The correct answer is based on safety regulations governing the minimum height requirements for outdoor service conductors. In residential and commercial settings, the National Electrical Code (NEC) specifies that service conductors must be elevated to prevent accidental contact and to protect them from physical damage. The height of 12 feet above ground level is mandated for conductors that pass over areas like sidewalks, driveways, and other locations where people may gather, ensuring a safe clearance. This height is significant to minimize hazards associated with accidental contact from individuals or vehicles, particularly in high-traffic areas. Not only does this standard enhance safety, but it also provides adequate space underneath the conductors for activities such as landscaping or construction without interference from the overhead electrical lines.
