According to ASME B30.3, an overhead power line is always considered to be what?

According to ASME B30.3, an overhead power line is always considered to be energized. This classification emphasizes the importance of assuming that power lines are live and capable of delivering an electrical shock. This is critical for ensuring safety during operations involving cranes and other equipment near power lines, as it necessitates taking appropriate precautions and establishing minimum clearance distances.

This approach is based on the potential hazards associated with overhead power lines, and it underlines the necessity for operators to treat them with extreme caution at all times. Operators are required to implement safety protocols, which may include maintaining a safe working distance and using insulating equipment when necessary, to protect against the risks posed by electrical current. This understanding is vital for ensuring the safety of personnel and equipment on job sites where overhead power lines are present.
