What minimum distance should unqualified workers maintain from 12kV power lines?

The minimum distance that unqualified workers should maintain from 12kV power lines is crucial for ensuring safety around electrical hazards. Maintaining this distance helps prevent accidental contact with live electrical components, which can lead to serious injuries or fatalities.

In the context of working near power lines, the National Electrical Safety Code (NESC) and various occupational safety standards recommend specific clearance distances based on the voltage level. For 12kV lines, the recommended minimum approach distance for unqualified personnel is typically around 2'11". This distance is designed to provide a safe buffer zone, considering the potential arc flash and shock hazards associated with high voltage.

Understanding this regulation is critical for anyone working in or around electrical installations to protect themselves from the dangers posed by electrical currents and maintain compliance with safety standards.
