There's a lot of designs of ceiling fans to select from out there. We have one in our kitchen. We do not need Air conditioning and we have about a number of days annually that it is very nice to possess the ceiling fan for air flow.
I had been conversing with one of my potential clients whose brand new home we are trimming out at the moment and the subject came around to the ceiling fan/light combination that's going within the family area. He informed me of his neighbor across the road who had hooked up a ceiling fan by just upgrading a light fixture on the ceiling. After about a 7-day period while it was operating they noticed the fan drop from the ceiling. No one was harmed, fortunately.
I reassured him that the fan going into the brand-new residence was solidly fixed onto a truss joist in the ceiling. Whenever I am done you will be able to suspend on that fan and it won't move around in the slightest from its anchor point.
If you would like to mount a ceiling fan within your house then, I propose that you make certain that it is safely anchored to a joist or ceiling column. The majority of ceiling light fittings today are hung on plastic-type containers which are nailed onto a joist with a couple of nails. These are explained in The National Electric Code (NEC) 314.27(A) as capable to hang accessories weighing under 6 lb.
For ceiling fans you will find a couple of specific features, they're in NEC 314.27(D), specialised boxes designated for up to 35 lb of fan, as well as those that could sustain a 70 lb fan. These kinds of boxes normally straddle a joist or column, or perhaps it has a very major anchoring device that covers between two joist/beams and suspends the fan concerning the joists.
Ceiling fan mounting base dimensions vary from the rather typical of approximately 4" diameter to 8". You have now achieved a decision stage. In the event you possess a fan with the small base, installing it on the joist without modifying the box will necessarily mean that the box will be subjected and probably the electrical wiring too. With the 8" base you are able to anchor it onto the joist and continue to cover the container.
I might think about utilizing a 3/0 pancake box (metal) or possibly a special fan container that straddles the joist. Obtain the edge of the joist (next to the current box), the joist is usually a 2x something so it is 1 ½ inch wide, therefore the center is ¾" from the edge. I then insert the 3/0 pancake on the ceiling and draw an contour of the brand-new box on the sheetrock. When you have a hole saw that dimension you may use it, otherwise use a razor blade to cut the rock away from the joist. I'd prefer to conserve the cut out piece of rock to make use of to be a filler instead of the old box.
Then, clear away the old box. This is completed with a stainless steel hacksaw blade to take the nails keeping the old box to the joist. Warning, you don't want to go heavy and cut or damage the wire into the box that's stapled near by. If the box is loose, take away the wire from it. Draw the wire over the ceiling, insert it in to the pancake box and anchor the box to the joist. The mounting ears of the container should be in line with the joist.
