Which type of raceway is addressed in Article 372?

The correct answer refers specifically to Cellular Concrete Floor Raceways, which are governed by Article 372 in the National Electrical Code (NEC). This article outlines the requirements and installation practices for raceways designed to allow for the routing and protection of electrical conductors within concrete floors that feature cellular structures.

Cellular concrete floor raceways are unique as they are designed to be embedded within the concrete itself and provide an effective solution for managing electrical circuits while minimizing visual and physical disruption. They allow for quick access and installation of cabling, which can be particularly beneficial in environments like commercial buildings where aesthetics and space management are critical.

In contrast, the other options do not fall under Article 372. Strut-type channel raceways, surface metal raceways, and multioutlet assemblies are categorized under different articles or sections in the NEC that address distinct types of raceway systems and their respective applications. Understanding which raceway types fall under specific articles is crucial for compliance with safety standards and proper electrical installation practices.
