Need to install ceiling fan box and wiring
 
Hi,

I am planning to install a ceiling fan, but my room does not have a ceiling fan. I am a newbie at installing the wiring and the box, so this will be my first time.

I assume that I will have climb into the attic and carefully walk on the joist.
I would have to measure where the center of the ceiling and insert a long nail so I can see it in the attic.
I would take the roll of wire up to into the attic and crawl until I find the inserted nail and drop the wire into the opening.
I would need to find an opening to where the wall switch is located and drop the wire done the wall. I do hope there is an opening. i noticed that from the center of the ceiling to the doorway, there is a ceiling fire alarm wired up.

When I get back down from the ceiling I would need to start cutting a hole with drywall knife and insert a bracket between joist. For the wall switch, I am assuming that I can connect the wire from the ceiling fan to the light switch, which turn on/off to one of the room outlets.

Is this a good and accurate plan? I want to make sure I have everything correctly plan.

Any advice or additional information is greatly appreciated.

Thanks,

JC

Sounds like you have a good idea of what to do. Here are some more tips.

1) Find the center of the room and insert a wire (I use a wire hanger) from below, up into the attic so you can find it. You need to mount a fan rated ceiling box where the fan will hang from.
2) Trace out the fan box from below and cut the hole so the box fits real nice. Make sure you are clear of the rafter before you cut the hole. Move over a little if needed.
3) Use a 2x4 in the attic to hold the box up. Screw the 2x4 to the rafters and screw the box to the 2x4. Note: ( they do make a kit for this. Box and expandable support arms). A fan rated box "MUST" be used.
4) You will need to drill a hole in the top of the wall plate where the switch will be located.
5) You will need to install an "old work" switch box.
6) You will need a power source for the fan.

Once you start, you will see what needs to be done. Just make sure the fan is on a strong support and a fan box is used.

Hi,

I mounted the ceiling fan with the Westinghouse Saf-T-Brace, which can support fans up to 120 lbs. My ceiling fan was about 30 lbs.

While up in the attic, I was looking for the opening to where the wall light switch is located. I found an opening where another wired was routed down the wall. I want to connect the ceiling fan power wire to the light switch. I was wondering how to snake the wire to the box. I will be doing this job on my own. I already mounted the ceiling fan and just got the power connection left to do. Any advise on how to complete the last steps. I am trying to avoid too many trips in the attic. Any help is appreciated. Thanks... -JC

If you drop a weighted string into the wall cavity you can sometime use a small hook through a knockout in the switch box to pull the string into the box. Once you get the string into the box you would tape the cable to the string and pull the cable into the box.

Depending on how the switch is wired you may need to make wiring changes at the receptacle.

Hi,

Thanks for the wire snaking tip. I removed the light switch panel. The light switch box is secured in the cutout. I am assuming that is nailed to the stud, but I am only guessing here. I have not taken out the switch or pulled out the existing wires.

How would I take out the light switch box without damaging the drywall? Do I just cut a large hole on top of the box to snake the wire or is there another easy way?

Thanks and very much appreciated!!

You may not even need to remove the existing switch box.

If you do need to remove the box you use a hacksaw blade to cut the nails between the stud and the box.

Thanks. If I do not need to take out the light switch box, do you recommended drilling a large hole in the box to snake the fan wire?

Jim Port 07-05-2012 08:50 PM

There should be tabs that you can punch out if the box is plastic or metal knockout you can remove.

I checked and it the cheap plastic box with not second push out. I will have to drill a large hole. I will try to snake the wire down to the second open on the box. Thanks for the tips.

If there's no room To snake the wire down to the box, you can always drill a new hole just to the right or left of the existing hole the old wire is using to go down . Just make sure you have enough distance that you don't accidently clip the old wire and that you are on the correct side of the stud that you want to fish down.

I know my attic had 2 wires feeding down so there was no more room to feed a 3rd wire down into the exsisting hole.

Thanks for the advise. I will charge up my drill. I am hoping to find the correct location of the wire that leads to the light switch.

Good advise here. Just trying to avoid too many trip in the attic because of the heat and insulation material.

I plan to finish up the wiring this coming weekend. I will post my update. Thanks.

If it was anything like my attic a standard bit isn't long enough, I had to buy a long drill bit to have enough room.

HI adgjqetuo, I took some time off and went up to the attic. Yeah, u are correct, I think I have to drill a hole on the wood board. I guessed wrong on the first wire, so I assume that it has to be the 2nd wire. For the newbies, it is a dark attic and it like a guessing game on the wires. I going back up this weekend to try again with the drill. If you got some tips, Thanks.. u have been helpful. JC

I had my wife tap on the ceiling near the switch to get my bearings in the attic. Once I was close to where I needed to be I took my voltage test stick to nearby wires as my wife flicked the switch on and then off as I was talking down to her. Once I found it it was easy to know where I needed to be. I labeled the wire up there too for any future reference.

Thanks. I will be back in the attic this weekend..
