Which of the following is NOT a listed raceway for power-limited fire alarm circuits in hoistways?

• A. RMC
• B. NMC
• C. IMC
• D. PVC conduit

Answer: (D)

Raceways for power-limited fire alarm circuits in hoistways must be listed for that specific use, providing the appropriate protection in the elevator environment. RMC and IMC are metallic raceways that are commonly listed for hoistway installations, offering strong mechanical protection. NMC, when listed for this application, is also an allowed option. PVC conduit is not listed for hoistway use with power-limited fire alarm circuits, so it’s not permitted in this particular setting. The takeaway is to choose a raceway that the listing specifically approves for hoistway fire alarm circuits, not just any conduit type.
