What is the minimum safe distance to a powerline during transit energized with 300,000V?

• A. 10 feet
• B. 4 feet
• C. 20 feet
• D. 16 feet

Answer: (A)

The main idea is that higher voltages require greater clearance to prevent arcing and electric shock. At 300,000 volts, you need enough gap to stop an electrical arc from jumping to you or a conducting path in normal conditions. Ten feet is the minimum safe distance because it provides a practical safety margin that accounts for variations in weather, dust, humidity, and movement, reducing the chance of arcing or incidental contact during transit. The other options either cut the gap too close for reliable protection (a few feet) or give more clearance than the minimum needed, though they’re not the standard minimum in typical safety guidelines. So, maintaining about ten feet away from a 300 kV energized line is the appropriate minimum practice to stay out of reach of arcing and shock hazards.
