What is the minimum clearance required for overhead outside feeder conductors operating at not over 1,000 volts over public streets?

The minimum clearance required for overhead outside feeder conductors operating at not over 1,000 volts over public streets is 18 feet. This requirement is established to ensure the safety of the public and to prevent accidental contact with electrical conductors. Adequate clearance is crucial in maintaining a safe distance between live electrical wires and vehicles or pedestrians below, thereby minimizing the risk of electrical shock or fire hazards.

In many regions, electrical codes and standards dictate these clearance requirements to ensure safety compliance in utility installations. The specified height helps accommodate larger vehicles that may pass underneath, as well as ensures that the overhead conductors are not within reach of individuals walking or standing in the street. This clearance is vital for both operational safety of the electrical system and the protection of the public using the streets.
