How far should ceiling suspended paddle fans be supported from the outlet box?

The requirement for how far ceiling-suspended paddle fans should be supported from the outlet box is based on safety and functionality to ensure proper installation and operation. The correct distance of 12 inches allows for adequate clearance and alignment of the fan to ensure it operates efficiently without risking contact with the ceiling structure or fixtures.

Installing the fan too close to the ceiling could lead to inefficient airflow and might impede the fan's performance. Furthermore, a 12-inch distance helps to provide enough space for the wiring and connections made at the outlet box. This distance also allows for safe access to the electrical connections and ensures the fans are stable while in operation, reducing the risk of the fan swaying or causing electrical issues.

Other options suggest distances that are either too short or excessively long, which could compromise the fan's effectiveness or safety. The code requirements aim to ensure that electrical installations are both safe and functional, and a 12-inch distance is recognized as a standard practice in these installations.
