Cilling Fan

Ok I just installed a cilling fan with 3 lights in my bedroom and I use
AWG # 14. I find out that the wire were #14 after I did everithing :D Now I just not sure if this wire is ok. If it will be ok or do I has to upgrade to #12.
Plus if any boddy can tell me how to find out like in this case if the wire is ok for such installation I mean any installation?

Ya lost me pretty early on with what you have going on there...but:

#14 = 15 amps MAX
#12 = 20 amps MAX
#10 = 30 amps MAX

80% of MAX rating for continuous draw which equates to:

#14 = 12 amps continuous
#12 = 16 amps continuous
#10 = 24 amps continuous

Hope this helps.:)

Yea like JP said. If your on a 15 amp breaker your probably fine. HS

(3) 150 watt lights draw a little more than 4 amps total. Even the least efficient ceiling fans aren't going to draw more than 5 amps ( a good fan might draw 3 amps). If that's all that's on the circuit you're under 10 amps fully loaded.

 brandon83 11-09-2005 03:27 PM

you should be fine, most cieling fans won't draw more than 5-6 amps with fan motor and lights on at the same time. 14 gauge wire is good for 15 amps

Well I have beside the fan 6 receptacles in the circuit with they are hardly used.
I know I'm not using more than 80%
Because 6x180=1080 plus the fan is about 4.5av
and the breaker is 15a
so 15x120x.80=1440 =1440 so this is no more than 1080
But I just wasn't sure if AWG#14 was ok for a ceiling fan with 3 lights.
But thanks jproffer that help me much.
And thank you all for your help.

Whoa, whoa, whoa...where'd you get "6 x 180"...what is the 180?

And when did 1440 become less than 1080...where have I been?:confused:

If you have 6 of what I assume are 15A/120V receptacles, plus 4.5 for the fan (is that calculated or as found on the fan info?), then you'll be OK (legal) on #14 conductors, as long as you only feed it with a 15A breaker. The breakers may trip, or may not, depending on the load you put on it, but thats not against code. The code requirements are written to protect poeple, not to make life more convenient for them.

You can also use a 20 amp breaker to feed six(or any number more than one) 15A rec. plus the fan and be legal IF, and only if, you change to #12 conductors.

;) :D
Well as I know when you calculate a circuit you has to calculate each receptacle at 180v even know there is only 120v
And about 1440 is less than 1080--------ooooopppsss----you right actually I mean 1080va is not more than 1440va.
How did I do this calculation?????
Well 6 receptacles x 180 volts = 1080va------why 180? Because is supposed to be best to calculate more that way you will never have a over load. Plus hey I still in school so don't expect everything I say is right.
Anyway.
Now 15a breaker x 120 volts x .80 = 1440va. And I supposed you know what the .80 is right?
See 1080+ 4.5 (cillin fan) = 1084.5 or 1085va still this is lass than 1440va
than's every one help.
And I hope I have everything right this time
:D

OK First off the 180 va only applies to commerical and indusrtial. Not counting the required outlets in a hoouse, kitchen, bath, laundry, the code has no requirements on the number of outlets on a breaker. That being said, local codes may, and do apply. Also, the .80 only applies to continuous loads, which in a house are also usually unheard of. You can load the 15 amp breaker to the full 1800 watts if you so desire. If you have only six outlets and a fan with lights you will be fine with 15 amp breaker and #14 wireUnless you are putting heaters, and coffee pots and such on this circuit. Anymore questions, just ask!
