    Question Would it be okay to put 2 Ceiling Fans on one circuit???

    Wondering if it would be okay to put 2 Ceiling Fans on one circuit if that is all that is on it? And would 14-2 be good or 12-2 with a 20 amp breaker???

    Have not got that far yet or better to go with 2 15 Amp circuits one for each of the 2 fans?

    Thanks,

    Including the light, ceiling fans won't use more than 150 watts total, so 300 watts for two. Check your fans to find specific numbers.

    A 15A circuit is rated for a load of 15 * 120 * 80% = 1,440W, so unless there is some bizarre and obscure code that says to the contrary I see no reason to not have two fans on one 15A circuit.

    Remember though that the gauge is determined by the breaker. If you have a 20A breaker, you must use 12 gauge wire throughout. If you put 14 Ga. wire on a 20A breaker, the breaker may as well not be there since the wire will fail before the breaker trips.

    Sure as long as you don't exceed the capacity of the circuit you can have as many as you want.

    If you're putting in a new circuit, by the way, just go with a 20A breaker and 12ga. The cost difference is negligible, and while 12ga. is a little harder to work with it's not that big a deal.

    That way you have much more capacity for future upgrades if needed.

    A little over dramatization there Doug, Although using 14 ga wire on a 20 amp breaker is not code it is also not likely to cause a failure of the wire.

    Thanks but will be controlling each fan with 2 3-Way switches so it might get a bit more in cost with 12-3 between the 2 3-Way switches. being 2 of the 3-Ways will be on the 1st Flr and the others on the 2nd where the fans will be. But it is a loft layout. So the 2 3-Ways will be for convenience of not having to run upstairs to turn them off.

    Also yes 14 gauge wiring for 15 Amp and 12 gauge wiring for 20 Amp.

    Appreciate the info.

    It won't cause a failure of the wire, no. But it does make the wire the weakest part in the circuit, which is contrary to the goals of the circuit breaker - to protect the wire. That's my understanding of the reason for the code.

    Sorry, didn't mean that to sound snippy. Long day at work and I'm feeling punchy. Time for a beer.

    Code requirements are for worst case scenarios and takes into account voltage drop and heat production. The code has a large safety margin built in. In panel wiring 14 ga wire is used for up to 42 amps. It is however always good to point to and comply with code requirements.

    I did not know that. Learn something new every day.

    And this is why I should probably stick to asking questions, instead of answering them
