What raceway type is known for its nonmetallic material, often used in residential applications?

The answer highlights the use of nonmetallic materials that are commonly found in residential electrical applications, making it a suitable choice. Nonmetallic wireways are designed to provide a safe and effective means of routing electrical wiring in situations where metal raceways might not be ideal due to corrosion, grounding, or safety concerns. These wireways are typically made from materials such as PVC, which is lightweight and easy to install, making them particularly favorable for residential settings.

In contrast, the other options represent raceway types that either use metal or are intended for specific applications that do not align with the typical requirements of residential wiring. Surface metal raceways, for example, are primarily used in commercial settings, where a more durable and protective pathway for wires is necessary. Cellular metal floor raceways are designed for more complex installations in commercial environments and may not be applicable to typical home environments. Similarly, strut-type channel raceways are often used in industrial applications to support electrical and mechanical systems, further distancing them from the context of residential applications.

Thus, the focus on nonmetallic materials in nonmetallic wireways makes it the ideal choice for the residential setting described in the question.
