When passing over roofs, coaxial cables shall have at least __________ ft of clearance from all points on the roof.

Coaxial cables passing over roofs must maintain a clearance of at least 8 feet from all points on the roof to ensure safety and compliance with industry standards. This requirement is designed to prevent physical interference and damage to the cable, which can lead to signal degradation or loss. Additionally, maintaining this clearance helps avoid potential hazards for maintenance workers and minimizes the risk of environmental wear and tear on the cables from roof movement, such as snow or debris accumulation. Compliance with this standard reflects good practice in maintaining the integrity of the electrical and communication installations.
