Answer :
Final answer:
PVC is the only raceway option allowed for installation in cinder fill without additional protection. Rigid Metal Conduit, Electrical Metallic Tubing, and Intermediate Metal Conduit all require further safeguards. PVC's resistance to corrosion and structural flexibility make it the ideal choice for this scenario.
Explanation:
Understanding Raceways in Cinder Fill
When installing raceways in cinder fill, it is important to choose the appropriate type that can withstand the conditions without requiring additional protection. In this context, the options provided are:
- RMC (Rigid Metal Conduit)
- EMT (Electrical Metallic Tubing)
- IMC (Intermediate Metal Conduit)
- PVC (Polyvinyl Chloride)
Among these options, PVC is permitted for installation in cinder fill without additional protection. PVC is non-metallic, lightweight, flexible, and resistant to corrosion, making it suitable for various environments including those with a cinder base. In contrast, RMC, EMT, and IMC typically require further safeguards, such as additional mechanical protection due to their susceptibility to damage in harsh conditions.
Conclusion
Therefore, the correct answer to the question is D) PVC.
