What is the requirement for an outlet box when installing a ceiling paddle fan?

The requirement for an outlet box when installing a ceiling paddle fan is that it must be listed and marked as acceptable for fan support. This is crucial because ceiling fans can weigh significantly more than standard light fixtures and generate vibrations during operation. An outlet box specifically designed for fan support is engineered to handle these loads safely and securely, ensuring the fan remains stable and preventing accidents or damage.

Using a box that is not rated for fan support can lead to various issues, including the box failing due to the weight and movement of the fan, which could result in the fan falling and potentially causing injury or damage. Therefore, it is vital to check for labels indicating that the box is suitable for fan installation, ensuring compliance with safety standards.
