Network-powered broadband communications cables attached to the building structure should be protected by raceway if located within how many feet of finished grade?

The correct response is that network-powered broadband communications cables should be protected by raceway when they are located within 8 feet of finished grade. This requirement is based on safety standards that aim to prevent damage to cables which can result from environmental factors or potential physical impacts.

Raceways provide a protective pathway for the cables, shielding them from moisture, debris, and other elements that could compromise their integrity. The 8-foot distance is significant because it represents a common threshold where these communications installations may be exposed to potential hazards, such as landscaping activities, pedestrian traffic, or animal interference.

This standard is consistent with electrical and communication installation codes, which emphasize protecting sensitive wiring in areas where they are most vulnerable to damage. Therefore, utilizing raceway within this specified distance ensures that the communication infrastructure remains reliable and uninterrupted.
