What is the minimum clearance required for a crane operating near a 250 kV energized power line?

The minimum clearance required for a crane operating near a 250 kV energized power line is 20 feet. This requirement is established to ensure safety and prevent electric shock hazards that can occur when operating equipment close to high-voltage lines.

When working with cranes, maintaining an appropriate distance from electrical lines is crucial because the high voltage can create a potential arc, which can reach beyond the immediate physical distance to the power line. The established clearance distances are based on the voltage level of the lines, with higher voltages necessitating greater clearance to ensure that operators and equipment are safe from electrical hazards.

In this case, the choice of 20 feet aligns with regulatory guidelines designed to protect personnel and equipment operating under or near power lines. Understanding these clearance requirements is vital for ensuring safety in rigging operations that involve cranes and electrical infrastructure.
