Question How do I put a ceiling fan box here?

In the middle of these recessed lights, how do I put a ceiling fan box and wire it?

You will have to cut the ceiling drywall between joists unless you have a open joist. Have to drill hole in each joist and pull wire.
You will also have to cut top of drywall you want switch mounted so you can drill and pull wire to the ceiling.
You need to pull power to new switch as well. Best place often will be from existing light switch.


If you don't mind ceiling fan powered with existing recessed lights, you could just pull power line from one of the lights. That way you can minimize drywall repairs.

No need to cut the ceiling between the joists if you follow the joists.

If your ok to run the cans at the same time as the fan, you could install the fan in the same joist space as the middle cans and fish a feed off one of the cans.

1. How do I run NMB from a recessed light in a finished ceiling?

2. Can I use a saddle box on a crossbeam that runs across two joists?

1. If you're in the same joist bay, you can pull the can out from below and stick your arm up there to pull the cable. If you're in a different joist bay, you may need to use a long flexible drill bit. These can get you an extra bay or two to the side.

2. You can install a cross beam or use one of the many old work fan boxes. They have various kinds of crank out and expandable support braces. For example: http://www.aimedia.co/media/spec-sheets/FBRS4200R.pdf

Note that if you feed the fan from one of the cans you will not be able to use a dimmer switch on the lights, and the fan will only run when the lights are on. If you want to control the fan separately you'll need to run wiring to the switch and/or another nearby circuit.

There is already a crossbeam where I want to put the fan box. The joist is in the background.

A saddle box or a pancake box would be your option.

You will need to use a fan rated pancake box and be limited to two wires plus a ground.

Yes, if it is solidly mounted.

What is stronger:

A. Fan-rated pancake box

B. Fan-rated Half saddle boxes:

As long as they are both rated for a fan they are both fine. One is not stronger then the other.

Both are just as strong, but saddle box may be better option because you will have more room for the wiring. You will need that room if you plan on installing remote controller.
With half saddle box type, you are screwing fan mounting bracket straight into the joist. So, it is probably stronger, but way more then you need.

Question

So if I push up one of the recessed light cans, I can access the junction box above?

You'll have to pull it down. Remove a couple screws or clips inside the can and the can will slide out of the mounting frame. You may have to cut or loosen up some of the drywall compound around the opening and it might take a little effort to get it to come out. You'll be able to access the junction box once the can is removed.

Depending on which recessed light was used, it may not be possible to access junction box above.
If it is remodel type, there are 3 clips that you can undo and pull the can down.
With most new installation types, you cannot access junction box above without cutting drywall. There are some that you can remove can from the frame by pulling it down and access. Some may require removing screws inside for access.

If you have non accessible type, you will have to cut drywall near or around recessed light to access junction box and patch.

I've never seen one that is completely inaccessible -- it would violate code and could not be approved for sale. They are a huge PITA to access, and you'll probably cut your hand at least once in the process, but they are accessible through the can hole. A pair of stubby screwdrivers will help.

Well. Its possible that I'm remembering something wrong. Cause I remember not being able to remove can, but when I search for pictures, all of them are removable.
May be it was because drywall was installed over the can.
Hm..

Look in the can and you will see three or four 1/4" hex head screws. Remove them and the main can housing will come down.

The junction box must be accessible by code. It may be a pain to work in, but it is accessible.

Thumbs up

Everything worked out fine.

I pushed can up into ceiling and accessed junction box easily.

Decided to put chandelier, not ceiling fan.
