Correct answer to question 6030
- B: By independent support wires, not the ceiling grid wires
Explanation
Wiring in a fire-rated floor-ceiling or roof-ceiling assembly may not be secured to the ceiling support wires. Independent support wires, distinguishable from the ceiling wires, are permitted. See 300.11 in NEC 2020 and 2023 (300.13 in NEC 2026).
