In which location is a multi-outlet assembly permitted to be installed?

A multi-outlet assembly can be installed in a dry location, which is the primary reason this choice is correct. Dry locations are defined as areas that are not normally subject to dampness or wetness and where the risk of moisture damage is minimal. In such spaces, electrical equipment, including multi-outlet assemblies, can function safely without the threat of moisture intrusion, which can lead to electrical hazards such as short circuits, corrosion, or electrical shock.

In contrast, while damp or moist locations may have some allowable installations under certain conditions, they pose higher risks due to moisture presence, which can jeopardize the safety and functionality of electrical equipment. Wet locations, which are subject to saturated conditions, also require special equipment designed for those environments to ensure safety against moisture-related issues. Therefore, the preference for installation of multi-outlet assemblies in primarily dry areas aligns with best practices for ensuring safety and longevity of electrical installations.
