Which of the following is used for wire management and is typically installed in walls or ceilings?

The installation of Metal Wireways in walls or ceilings serves the essential purpose of providing organized containment for electrical wires and cables. These wireways are designed to facilitate efficient wire management while ensuring the protection of wiring from physical damage and reducing the risk of electrical hazards. Metal Wireways are particularly advantageous because they are durable and can handle a variety of environmental conditions, which makes them suitable for both indoor and outdoor applications.

Moreover, the metallic construction contributes to grounding and bonding capabilities, enhancing safety by providing a path to ground in case of an electrical fault. They are often utilized in commercial and industrial settings where wire organization is critical to ensure compliance with safety standards and to allow for future maintenance or modifications with ease.

In contrast, the other options—Surface Nonmetallic Raceways, Cablebus, and Multioutlet Assembly—do not share the same characteristics or typical applications as Metal Wireways when it comes to installation within walls or ceilings. Surface Nonmetallic Raceways are usually visible on the surfaces of walls, while Cablebus is more suited for high-capacity electrical distribution. Multioutlet Assemblies are generally utilized for plugging in equipment rather than for wire management within walls or ceilings.
