___________ deck can be used to provide a chase for electrical distribution.

1. Cellular

2. Composite

3. Metal deck

4. Solid deck

The correct answer is: Cellular

A cellular deck is designed with a series of openings or cells that allow for the passage of electrical wiring and distribution. This structure is beneficial because it provides a concealed space for running electrical conduits without the need for additional construction, allowing for a neat and organized electrical distribution system. The integrated channels help manage the routing of electrical systems while maintaining the integrity and aesthetics of the ceiling below. Cellular decks are particularly favored in commercial construction settings where extensive electrical installations are typical. They help streamline the installation process and reduce the risk of exposure to wiring, enhancing safety and compliance with electrical codes. In contrast, the other types of decks do not provide the same level of support for electrical distribution. Composite decks are primarily used for their structural strength, metal decks offer durability but lack the enclosed spaces for wiring, and solid decks do not feature any openings for conduits, limiting their functionality in this context.
