What is the required minimum clearance between power lines rated at 50kV and any part of a crane or load?

The required minimum clearance between power lines rated at 50kV and any part of a crane or load is indeed 20 feet. This clearance requirement is established to ensure safety for workers operating cranes near high voltage power lines, as an electric arc could occur if any part of the crane or load comes too close to the power lines. Maintaining a distance of 20 feet helps mitigate the risk of electrical hazards, such as electrocution or electrical shock, which can be fatal. This clearance distance is a standard guideline set by safety regulations, emphasizing the importance of maintaining a safe working environment when operating heavy machinery near potentially dangerous electrical infrastructure. Understanding and adhering to these clearance regulations is critical for the safety of all personnel involved in crane operations.
