According to ASME B30.3, what is the prohibited zone distance from power lines that are 60 kV?

The correct distance for the prohibited zone from power lines carrying 60 kV, according to ASME B30.3, is 15 feet. This regulation is crucial for ensuring the safety of workers and equipment during crane operations. The specified distance helps prevent accidental contact with electrical lines, which can lead to electrical shock, fires, or other hazardous situations.

The rationale behind this distance stems from the need to account for factors such as the potential for sagging lines and the movement of the crane and its load. This clearance allows for a safe operational buffer, minimizing the risk of electrical hazards while maintaining the efficiency of crane functions. Compliance with these guidelines is paramount for crane operators to safely perform their jobs without putting themselves or others at risk.
