Outlet boxes that are designed to support paddle fans must indeed be listed and marked by the manufacturer as suitable for this specific purpose. This requirement ensures that the box can safely handle the weight and dynamic forces associated with the operation of the fan, which typically includes a significant amount of vibration. The listing and marking indicate compliance with safety standards and confirm that the box has been tested under conditions that mimic real-world use.

This requirement is in place to help prevent electrical hazards, such as short circuits or fires, that could arise from using an inadequately rated box for heavy fixtures like paddle fans. A box that is properly rated and labeled for fan support provides assurance that it has been engineered to maintain structural integrity while accommodating the electrical connections necessary for the fan's operation. Adhering to this guideline is crucial for ensuring both safety and functionality in electrical installations.
