For power lines rated at less than 50kv, what is the required minimum clearance for crane operations?

The required minimum clearance for crane operations near power lines rated at less than 50 kV is 10 feet. This clearance is established to prevent electrical hazards and ensure the safety of personnel and equipment on the job site. The 10-foot clearance is based on industry standards and regulations, which recognize the risks associated with working near power lines, such as electrical shock and arc flash. Maintaining this distance allows for safe operation of cranes and reduces the likelihood of inadvertent contact with the lines, which can have severe consequences.

The rationale behind the 10-foot requirement is rooted in ensuring that enough space is maintained to protect workers from potential electrical exposure while allowing for the necessary operational flexibility of the crane. Therefore, 10 feet is a widely accepted standard that supports safe practices in construction environments where cranes and high-voltage power lines coexist.
