What is the minimum vertical clearance required for open electrical service conductors over public streets?

The minimum vertical clearance required for open electrical service conductors over public streets is typically 18 feet. This requirement is intended to ensure safety and prevent accidental contact with vehicles or other objects, which could lead to electrical hazards or outages.

Maintaining this clearance helps protect both the public and utility workers, as it reduces the risk of electrocution and potential damage to vehicles. Regulations governing this standard are typically derived from the National Electrical Safety Code (NESC) and may be adopted or adapted by local jurisdictions.

While some options suggest lower clearances, they do not meet the minimum safety standards typically enforced for electrical installations in public areas. Adhering to the 18-foot measurement safeguards against various safety risks associated with low-hanging electrical lines.
