Frequently Asked Questions

How do amps compare to watts?

For comparison, one amp is equivalent to 120 watts, based on 120V input voltage, so 0.5 amps would be 60 watts. This measurement and comparison for electricity is standard at all times. If voltage drops to 110, then one amp equals .54 amps, and so forth. 

How many ceiling fans on a 15 amp circuit?

A 15 amp circuit should be able to run 4 ceiling fans without any problem. For example, a 52 inch fan is between 90 and 100 watts at a high speed setting with three 60 watt light bulbs. That means that each fan will use around 280 watts. A 120 volt, 15 amp circuit can supply 1880 watts. Four fans at 280 watts each is about ⅔ of the total wattage that can be on the 15 amp circuit.

What size wire is needed for a ceiling fan?

The minimum size wire that is required for a ceiling fan is 14-2 gauge wire, which is standard for lighting or fans, but if your fan has an adjustable switch or speed control, 14-3 wire is needed.
