2008 NEC 314.20-Ceiling boxes--employing a flush-type cover????

[prorod67]

Ceiling box for light fixture/fan, as I see it does not employ a flush-type cover. New to residential wiring, so please excuse me. But as I read the code, it should not apply. Am I wrong, and if so, what part am I missing?

It is not clear at all what you are asking.

Was just looking for opinions on ceiling boxes. As I read the code, 314.20 and the 1/4" rule, it applies to "boxes employing a flush mount cover". I am installing ceiling fans or light fixtures to all ceiling boxes, none of which are flush mount covers. My question is ( i guess) does 314.20 require me to mount light/ceiling boxes to within the 1/4".

Which code reference are you referring to?

It's right in the title, from the 2008:

314.20 In Wall or Ceiling. In walls or ceilings with a sur-
face of concrete, tile, gypsum, plaster, or other noncombus-
tible material, boxes employing a flush-type cover or faceplate
shall be installed so that the front edge of the box, plaster ring,
extension ring, or listed extender will not be set back of the
finished surface more than 6 mm ( 1 ? 4 in.).
In walls and ceilings constructed of wood or other com-
bustible surface material, boxes, plaster rings, extension
rings, or listed extenders shall be flush with the finished
surface or project therefrom.

I think I see your question.
The wording "boxes employing a flush-type cover or faceplate" would indicate it might my apply to a ceiling fan.
IMO, the "backplate" for the ceiling fan would be considered a 'faceplate".

They make box extenders to cover the gap if the box is further than 1/4". These are made by Arlington

Just curious...I probably missed it, but could not find a definition for flush-type. Does this basically cover everything installed in noncombustibles must be 1/4" or are there situations otherwise.
