Which type of raceway is primarily nonmetallic and suitable for various indoor wiring applications?

Surface nonmetallic raceways are specifically designed for indoor wiring applications where nonmetallic materials provide advantages such as resistance to corrosion, ease of installation, and lower cost. These raceways are typically made of materials like PVC or other plastics, making them lightweight and easy to handle compared to metal alternatives.

The nonmetallic composition is particularly valuable in environments where moisture and chemicals may be a concern, as they do not rust or corrode like metal materials can. Additionally, their design allows for a clean and aesthetically pleasing installation, as they can be easily painted or blended with existing interior finishes.

This type of raceway is versatile and can accommodate a variety of cable types, making it suitable for residential and commercial applications. The ability to manage wires while providing protection and maintaining a neat appearance is crucial in many indoor scenarios, enhancing both safety and overall aesthetics within the space.
