What should be the vertical clearance between overhead service drop conductors and any roof they pass over?

The vertical clearance between overhead service drop conductors and any roof they pass over is critical for ensuring safety and compliance with electrical codes. The requirement for an 8'6" clearance is designed to prevent accidental contact with the conductors by individuals on the roof, as well as to protect the integrity of the electrical service and reduce the risk of electrical hazards.

This standard clearance helps mitigate the risk of personal injury to maintenance workers or anyone who may be on the roof. It also accounts for any potential structure movement or maintenance activity that might occur closer to the conductors. Adhering to this clearance is important in avoiding violations of safety codes, which strive to ensure both occupational and general safety around electrical installations. Hence, the specified clearance ensures compliance with safety standards and serves to protect life and property.
