Texas Fire Alarm License Practice Test

When located within 7 feet of the floor, how shall cables be secured?

1. Cables shall be fastened at intervals of 24 inches

2. Cables shall be placed at ground level

3. Cables shall be fastened in an approved manner at intervals of 18 inches

4. Cables do not need to be secured at this height

The correct answer is: Cables shall be fastened in an approved manner at intervals of 18 inches

When cables are located within 7 feet of the floor, they must be secured at intervals of 18 inches in an approved manner. This requirement ensures that the installation maintains safety and prevents any potential hazards related to loose or improperly secured cables. Securing cables at this height prevents them from hanging freely, which could create tripping hazards or damage to the cables themselves. Proper fastening is critical for both functional reliability and to comply with safety regulations, minimizing risks in both residential and commercial settings. The emphasis on an approved manner for fastening means that the method used should adhere to industry standards, ensuring that the installation meets code requirements. Using materials and methods that have been evaluated for safety and effectiveness contributes to the overall integrity of the electrical system.
