What is the maximum clearance required from a 50kV power line?

• A. 5 feet
• B. 10 feet
• C. 15 feet
• D. 20 feet

Answer: (B)

For a 50kV power line, the National Electrical Safety Code (NESC) specifies that there should be a minimum clearance of 10 feet to ensure the safety of individuals working nearby. This distance is crucial for preventing accidental electrical contact that could result in serious injury or fatality, especially for workers who may be using equipment that could inadvertently come close to the power lines. The rationale behind this standard is based on the potential for electrical arcing, which can occur if someone or something comes too close to high-voltage lines. Maintaining this clearance helps create a buffer zone to protect workers from electrical hazards. Adhering to this guideline is vital for safety in telecommunications tower work, where technicians often work at heights and in proximity to such power sources.
