I respectfully disagree with the your interpretation of the canopies/domes.
370-16(a) permits using the volume of the canopy/dome. I believe the exception you are referencing is to allow for those fixture wires not to be counted as part of box fill.

Pierre,
370-16(A) (and 314.16(A)) talks about "domed covers, extension rings, etc that are marked with their volume in cubic inches..".
I've never seen a fixture canopy that had its volume marked in cubic inches. If this is a 4 cu. in box what code section allows 3 #14s to be in it?

This came up before. I have also never seen a canopy with a volume indicated ?
However, wouldn't the volume be based on a (pancake) box with a blank cover installed?

The ones that I usually see are used in residential and are non metallic (without the clamps).
With that in mind, how do you view it as an inspector? What do you allow or not allow? I will permit (1) 14-2 cable and no more at the rough stage. My reasoning is that I see very few lights with the volume marked on the canopy, and I don't want people having to change out their expensive lights because the rough doesn't comply. Any thoughts on this?

Ryan,
Would you flag a 14/3 NM installation to a pancake for a ceiling fan?
This is commonly installed around here.

Yes I would, unless the installer could show me that the fan has a volume allowance in the canopy. Otherwise I would ask for a "4-O" box instead of a "3-O" box.

Are "pancakes" rated for a ceiling fan (50 lbs, off the top of my head)?

Thinkgood,
There are specific pancakes designed for fans and heavier fixtures.

The problem with these things is that they are often installed so that they are not flush with the wall surface.
Has anyone ever seen extension rings for them?
