i have a hanging light and a sealing fan that i need to install..i have a three-way switch installed already for the fan... i would like them to be on different switches.. can i continue to run my 14-3 wire up to them control both fixtures but on different switches???? like give the fan the black wire and the light on the red ??and tied the white together and grounds together

 

What do you mean by "different switches"? Do you mean that you would like to have one pair of 3-way switches control the fan motor, and a second pair of 3-way switches control the fan light? Or would you like to have one of these two existing switches work the fan motor and the other work the fan light?

So do I infer correctly that you currently just have one pair of 3-way switches (perhaps at two entrances to the same room) that were installed by somebody other than you? And perhaps this used to operate a light? If not, what did it previously operate?

 

Yes, you need to explain yourself better.

Are these switches together? Are they on opposite sides of the room?

What is the entire setup?

 

sorry i'll try again..
i'm wireing my log home ,, ,,i have 2-- 3-way's set up now in the same box.. one i would like to give power to the fan ...fan has no light ...on the other side of the room i have a hanging light. i have with 14/2 for power coming in and 14/3 crossing over to the other switch...my question is the wire going up to fixtures do i have to run 2 different 14/2 wires,or can i just run a piece of 14/3 to run both???



thanks inadvance

 

It's still very confusing.

You mention that you have two 3-ways switches in this double-gang box. But where are the other two 3-way switches?

 

ok i have 2 --3-switch metal gang boxes one on either side of my house.i have installed 2-different-3-way switches set ups.....two switches on the right side of the house and two of them on the left side of the house i want one of the 3-way to control the fan and the other 3-way controls the light...the light on one circut and the fan on the other there is no light on the fan...can i use 14/3 to power both fixtures or do i have to run2 seperate 14/2 wires

 

Okay,

Now we have a picture (I think) of what your setup is. Now we need to know the wiring. Where does the power comein, are the three way switches already wired, etc.

Three way switches can be wired in a variety of ways. With one device on one side of the room and the other device on the otherside of the room, I might use two different methods to wire the devices, or I might wire them the same way.

 

Your description is still confusing, but I think that I can make sense of it.

You have two double gang boxes.

In each double gang box you have two three way switches.

You want to use a pair of three ways switches (one from each of the double gang boxes) to control a lamp.

You want to use the other pair of three way switches to control your fan.

You have a 14-2 coming into one of the double gang boxes to supply power.

You have a 14-3 going from this gang box to the other gang box for the three way switch loop. ===> Note: you _must_ have a 14-3 for _each_ of the three way switch loops. This means that you would need _two_ 14-3s between the double gang boxes in order to use _both_ three way switches.

You are then going to run a cable (or cables) from one of the switch boxes up to the lamp and fan.

Yes, you can run a _single_ 14-3 cable to do this. The black would supply switched power to one of the fixtures, and the red would supply switched power to the other fixture, and the white would be the return for both.

What Winnie siad is true with very important fact. The fan and the light must be drawing power from the same breaker. If they are on separate circuits then you must run separate neutral(white) wires.
Tie all the grounds together even if they are on separte circuits.
