Ceiling Fan Installation
 
I am in the process of replacing a 52 inch ceiling fan in my great room with a 60 inch Hunter ceiling fan. The existing fan has a 48 inch down rod that hung with a "ball" from the bracket that was attached from the box in the ceiling. The Hunter fan does not use a "ball" but has a mounting plate that is supposed to be somewhat flush to the bottom of the electrical box in the ceiling and then you attach the own downrod to that somehow.

My issue is, how are you supposed to attach the Hunter mounting plate to the electrical box? Are you supposed to drill holes through the top of the electrical box to run the 3 inch screws through the plate and up through the electrical box into a wood support that is supposedly above the box in the ceiling for support? The "ball" bracket on the existing fan attached to the electrical box by using screws and going through the bracket into holes that are already on two corners of the box. Very simple...

What is the best way to procced here? Thanks for your assistance.

Your ceiling box needs to be rated to carry the weight of the fan. The fan will attach to the ceiling box.

So are you saying that I need to replace the box?

Not nessicerely, if the fan is supported by the structure than that will work as well.

Also, what type of box is installed at the moment? Is it already a fan box? If so then just re-use the screws that you removed, all fans pretty much go up the same way. ALL fans will come with long screws even though you may not have to use them. You need to find out what type of installation your dealing with.

I'm assuming that it is a fan box. does it look different than a non fan box? I just removed a fan from this box to put up a different one. I am also assuming that there is already a fan brace in the ceiling since I just removed an existing fan.

If I use the screws that I took out of the "old" fan, would that be sufficient to hold the heavier fan? Is screws enough to hold the fan to the box? Thanks!

Without knowing what box is installed I cant answer your question. Any alot of people install fans without the proper support... so your orignal fan could have been illegal....


Can you see a model # on the box? a picture would be the easiest.

How is the box installed? Is it nailed to the side of a joist(not a fan rated install) or does it have a bar behind it with a nut in the center of the box holding the box to the bar(probably a fan rated box)?

I have looked in the attic above some other fans in my home and a piece of 2 x 4 has been nailed between two joists for support and it appears that the box has been attached to the board. I am assuming that this is what has been done for the fan in my great room. I will send picture shortly. Thanks!

If the box is plastic it is not fan rated.
I believe fan rated box are stamped inside with the weight rating.

kennykenny 07-08-2008 02:46 PM

It's not plastic it's metal

I put a ceiling fan up at home, using ceiling fan box, the fan attached using the ears on the box, when doing a bigger size ceiling fan at work, instructions called for placing the bracket onto the ceiling box by using 3" screws, that screwed up through the ceiling box. I used the existing holes in the box, but I guess you could drill new holes in the box to put the long screws through. on the screw length, maybe 2 1/2" but they are long.

after looking again at your present box, that looks like a regular box, the ceiling fan boxes I've seen are much shallower, and they are heavier guaged. I was told that the ears on a reg. box aren't strong enough to take the movement of a ceiling fan and the ears will snap off. Now, I have seen a regular box used like that but the brackett for the fan had the screws going up through the box and into wood.

THE BOX DOES NOT HAVE TO BE A FAN BOX.... with that said, if you screw the fan bracket to the 2x4 above the box its a legal install... :thumbsup:
