Question: 1 / 400

What is the minimum vertical clearance required for communication wires and cables above all points of the roof they pass over?

6 feet

7 feet

8 feet

The minimum vertical clearance required for communication wires and cables above all points of the roof they pass over is 8 feet. This distance is established to ensure safety and accessibility. Maintaining a clearance of 8 feet helps prevent accidental contact with the wires, particularly in areas where people or equipment may frequently pass underneath.

This standard is intended to withstand various environmental factors, including potential snow accumulation or other temporary obstructions that might reduce the effective clearance. The requirement also facilitates adequate space for maintenance and repair activities while adhering to building codes and safety regulations.

In considering the other options, they either do not provide sufficient clearance to ensure safety and accessibility or exceed what is specified in the applicable codes for communication lines.
