What type of outlet boxes must be listed for the future installation of a ceiling-suspended fan in a habitable room?

For the installation of a ceiling-suspended fan in a habitable room, it is essential that the outlet box is specifically listed for such use. Boxes that are listed for the installation of ceiling-suspended fans are designed to support the weight and movement of the fan, ensuring safety and stability.

Selecting an outlet box that is rated for dwelling occupancies means it has been tested and approved for the conditions typically encountered in residential settings. These boxes must be able to withstand the potential dynamic loads generated by the fan's operation over time, which is crucial for preventing accidents or damage.

Using outlet boxes that are not specifically rated, such as standard or temporary boxes, may not provide the necessary support and safety, especially in a habitable room where proper installation is critical to the integrity of the electrical system and the safety of the occupants. Non-habitable room boxes similarly would not comply with the requirements for appropriate load-bearing capacity and stability for ceiling fans. Thus, the only suitable choice for this application is one specifically designed for dwelling occupancies to ensure compliance with the NEC and safety standards.
