I'm planning on installing 2 ceiling fan, 1 in each of 2 bedrooms. There's no electrical on the ceilings and need to come down from the attic. The attic has several different white plastic contained wires running throughout the attic. I'm wondering if I should splice from 2 separate sources, or is it OK to splice off one source to create the 2 separate wires I need going in 2 separate rooms below for the ceiling fans.
I bought 50 ft. of 14-2 NM-B with ground. I know how to splice off an existing wall plug outlet, but haven't spliced off a whole line. I only bought 1 large metal junction box with cover.
Also, should I going into a 15 AMP circuit, or is a 20 AMP circuit OK to use for a ceiling fan.
So many questions. Thanks in advance. :confused:

You can use either a 15 or 20 amp circuit but if it is 20 amp make sure you are using 12-2 or 12-3. Since you already bought the 14-2 I would use a 15 amp circuit.

Both fans can be on the same circuit, make sure if you are adding them to an existing circuit it is not one that is already "full".

Thanks for the info.

Let us know how it works out!

Unfortunately, I'm installing these fans from scratch. I have no existing fixture in the ceilings. I do plan on splicing both of these fans into an existing splice I have in a junction box in the attic. I'm putting in a larger metal junction box, and running both new lines into the current splice. I'm just hoping there's enough juice to handle both.
Thanks again for your help. :)

Please, please, before you cut into any wires, make sure you have the correct breaker cut off. It will also help if you know what is connected to the other end of this circuit so that you do not inadvertently create an overload condition.

Also, just as a suggestion, when you make the cut, realize that you need to re secure both sides of the wire within 12 inches of entering the junction box. You will need wired clamps if you are using a metal box. Also, when you are finished setting up the box, mark on the cover what is connected inside the box.

Thanks for the info Don F. Believe me, I'm petrified when I work with electric, and actually shut off every single circuit breaker in my place. I located an existing plastic small junction box that has a Romex cable coming in and it's spliced with what I think is the upstairs bathroom exhaust fan. I plan on replacing that small junction box with a larger metal junction box that I bought with a cover. Today I bought 4 metal 1/2 cable clamps and some assorted wire nuts at Lowe's. I had already bought 50 ft. of 12/2 Romex which will be plenty to serve both areas where I'm installing the fans.
Now, I just need to cut a hole in the ceiling after tracing the outline of the fan box attached to the stability bar I bought to nail in between the 2 flr. Joists in the attic. I'm assuming that the box needs to be flush with the bottom of the ceilings which in my case have a wood cross strap going across them in the attic giving a good 1/2 to 3/4" gap from the bottom of the joist to the top of the ceiling sheetrock. That will make it so I have to lower the fan box an additional 3/4" so it won't be set too high above the ceiling.
I may attempt to tackle after work each day this week or after next wknd. I'll keep you posted on the outcome. Thanks.

Suzie,

This is where you need to know what is connected to the other end of the branch circuit. I doubt that it is just the bathroom light and exhaust fan.

You need to know for certain what is there.

On that circuit, there are other outlets in the bathroom and outlets in the 2 upstairs bedrooms as well. Nothing major though.

Apparently, the junction box I added my wires into had wires in there in which one of the 2 sets of wires was connected to a 3 way switch somewhere along the line, and although my 2 fans worked, the hall light also went on very dim and the switch wouldn't shut it off.
I had to break down and call my electrician who had it rewired to a different junction box in about 45 min. He also check out my wiring in the attic to the fans, and the support fan boxes I put in the attic as well.
He said I did a good job and for a rookie wouldn't have known that a 3 way switch was connected within that junction box.
Alls well that ends well. It was a lot of effort put into installing the fans. Frustrating at times, but the fans are awesome. I'm so glad they're finally in and working.
Thanks for your suggestions.

Good job. Especially that the electrician approved of your fan installs.
