Where are ceiling-suspended (paddle) fans required to be installed?

Ceiling-suspended (paddle) fans are required to be installed in boxes that are specifically marked for fan installation due to the weight and motion involved in their operation. These marked boxes are designed to support the additional load and the dynamic forces generated when the fan blades are in motion. This ensures safety and prevents potential hazards, such as the fan falling or electrical failure.

Boxes marked for fan installation typically comply with more rigorous building codes and standards, which means they are constructed to handle greater weight and stress. This is crucial because paddle fans can exert significant torque and thrust, which standard junction boxes may not be able to withstand. Compliance with this requirement helps to ensure that the installation is safe, meets electrical codes, and protects the longevity and functionality of the fan itself.
