What is the minimum clearance a crane in operation can maintain from a 250 (kv) energized power line?

To ensure safety when operating cranes near energized power lines, specific clearances must be maintained to prevent electrical hazards. In this case, the correct distance of 20 feet is in line with safety regulations set by organizations such as the Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI). These regulations stipulate that a minimum clearance of 20 feet should be maintained from power lines energized at 250 kV to protect workers and equipment from the risk of electrical shock or accidental contact.

This clearance distance is designed to account for various factors such as the possibility of swinging loads and the electrical field around high-voltage lines. Maintaining this minimum distance minimizes the risk of arching and ensures that the crane operation is conducted safely without interference from the electrified surroundings.

The other distances provided, while they may seem reasonable, do not sufficiently comply with the established safety standards for high-voltage lines, which specifically recommend the 20-foot minimum clearance in this context.
