Ceiling fan horse power ratings:
The majority of modern ceiling fans use less than an amp, averaging between 0.5 and 1 amp, depending on the model and the setting. One amp drawn by a ceiling fan is equivalent to about 120 watts. Low settings use less amperage while higher settings use more. Horse power ratings vary from 1/60 to 1/3 hp and should work with any ILLUMRA relays.
