For which reason must ceiling fans be specially supported?

Ceiling fans must be specially supported primarily for reasons of safety and structural integrity. Ceiling fans can be quite heavy and, when in operation, create movement and potential vibrations. If they are not properly supported, this can lead to the fan becoming loose or falling, posing a safety hazard to anyone in the vicinity.

Additionally, a securely mounted ceiling fan helps ensure it operates correctly without excessive swaying, which could strain the electrical connections or support structure over time. Proper support involves using designated support brackets or boxes that can hold the weight of the fan and accommodate its motion. This installation practice also protects the wiring connections from undue stress, which can lead to electrical failures or short circuits.

While aspects like aesthetics and grounding are important in overall electrical work, they are not the primary reason for the special support of ceiling fans. The focus should be on the safety and structural integrity to prevent any mishaps while the ceiling fan is in use.
