How is an overhead power line classified according to ASME B30.3?

An overhead power line is classified as energized until the power company verifies that it is not energized according to ASME B30.3. This classification is critical for safety protocols in crane operations and other constructions involving heavy equipment near power lines.

The reasoning behind this classification lies in the inherent dangers associated with unverified power lines. The assumption that a power line remains energized helps ensure that operatives maintain a high level of caution and follow necessary safety precautions while working in proximity to these lines. This includes maintaining appropriate distances and employing safety measures to mitigate the risk of electrocution or other electrical hazards.

Understanding that power lines are treated as energized until confirmed otherwise reinforces the need for clear communication with utility providers and proper verification processes. This knowledge is vital for crane operators and personnel involved in site operations to ensure the safety of the work environment.
