Wiring ceiling fan with can lighting

Hi,

I can't seem to wrap my ahead around the wiring on this one! That's nothing new though.

Anyway, this is a garage conversion that currently has one fluorescent shop light in the center, controlled by a switch at the garage's outside entry door and a switch at entrance to house. I have installed 6 can lights in the ceiling and will add a ceiling fan in the center of room, replacing the shop light.

I have discovered that the switches each have a 14/2 wire going to them, with no wire leaving their boxes. I assume this means the power goes to the shop light first and the switches are on the end?

I would like the ceiling fan to have constant power to it (we'll use pull chain), however would like to have the new can lights on a switch or dimmer switch. How would I go about using the same circuit for both the fan and lights?

I have attached a very crude diagram below. Oh, the can lights will be using low power LED bulbs.

Thanks for any help!


Howard

Well, It's time to start fishing...

There are several ways to do this. You will be changing the two switches to 3-ways, so you need to pull new cable.

You will need to run a new 14/3 between switch box 1 and switch box 2.

There are more steps but let's see if you're willing to do that for now.

Hi Brian,

Oh absolutely, I have no problem pulling cable and am fairly adept at making connections and such stuff.

Thanks for the help!

Start by changing out ceiling box to a fan rated one.
Run new 14/3 w/ground between 2 switch boxes. (assuming 15amp breaker)
Confirm and leave source power at fan ceiling box.

The next step you have a choice, whichever is easiest.
- Currently, you have 2 14/2 cables going to ceiling box from each of the switches.
One of these cables will be moved to first can light location you want to wire.
One of these cables will stay at (new) fan box and feed power to either one of the 3-way switches.

You still need to wire switches, I or another will explain that later. Cables first.

Here is one way to consider if you are on 2008 NEC or earlier. Does not meet 2011 NEC or later.

Thanks, Brian. I will get material this afternoon and run the cable between the 2 switches in the morning as well as relocating the existing cable from the switch to the first can light.

Ray, thanks for that. I think I'll stick with Brian's way as I can see where he's going with it.....and he was first!

There are almost always multiple ways to wire something. Which is best is often a matter of opinion. The diagram is my opinion of simplest with existing cables but if you are on 2011 NEC a more complicated wiring is necessary to satisfy the requirement for a neutral in each switch box even if not needed.

Thanks Ray, it's an older house from the late '70's. After finally understanding your diagram, I see you were both on the same page. It's about as efficient as it gets with what I have already in place. I have the material now, guess I'll get it done in the morning. Good stuff for a rainy day!

Thanks to both of you!

I didn't include the second 3-way switch but the wiring is basic. Be sure the black goes to common. The red and white travelers are interchangeable.
