You made the comment that we were assuming the ECG inside the box to be 14 AWG, but that it was 12 AWG and could be considered as causing us to exceed the volume calculation. However, as you also showed, 314.16(B)(5) says that the calculation will be made on the largest "entering the box." The ECG that comes preinstalled in the box does NOT "enter the box."

When a fixture is connected to a pancake the space it provides for wire connections should be taken into account when calculating max fill values. 314.16 (A) Box Volume Calculations. The volume of a wiring enclosure (box) shall be the total volume of the assembled sections and, where used, the space provided by plaster rings, domed covers, extension rings, and so forth, that are marked with their volume or are made from boxes the dimensions of which are listed in Table 314.16(A).

I wonder if an inspector might look at that "bushing" as being an internal cable clamp (314.16(B)(2) which I believe would bring the required space to 8.25
@SparkyChannel3 жыл бұрын
They might. The actual truth is that inspectors might say just about anything. But most of that clamp is outside the box so just about everybody would agree that it's an external clamp and not counted. Also, there is a picture in the 2020 NEC handbook with a set-up just like mine. Good question. Merry Christmas! 🎄

Thankfully, CEC is much nicer. We only count insulated conductors, so the ground is out. And #14 AWG only uses 1.5 cubic inch per insulated conductor. Although, we have a rule that counts every two wire-caps as an insulated conductor. So our fill only goes up to 4.5 cubic inches. Also, where are you getting 6 inches from for pancake boxes. The number I googled says they're 5.5 inches cubed.

Why use a bonding jumper when you can wrap the romex bonding wire around the green screw it’s self? Even if we used a 14 awg jumper and don’t have to count it, it still does take up some room. I also like using small orange wire nuts in that situation because they are smaller then the wagos. We don’t have to figure them in for box fill code wise but in reality they do take up room and depending on the fixture bigger wire nuts or wagos can get in the way.
@kenbrown28083 жыл бұрын
I agree. I'll also have to double check when I get my handbook, because I prefer the 3.5" pan box, which is only made legal by the volume of the fixture canopy, so if they've started to prohibit adding canopy volume, I'll have to find another way to get box volume without cutting into my margin of error by using 4 inch boxes. also, if you haven't played with them, I like the 3M O&B wire nuts for connecting fixtures in close quarters.

My boss, as I was an apprentice, never let use use 3” pancake boxes and so i still don’t. Usually fixtures thar require a small splice box NEED a metal 1gang box, because of the size and shape of the canopy. I’m always surprised they are allowed to make such fixtures seeing as how there’s no boxes technically rated to hold them. (As far as i know) And I’ve never seen a 1gang metal mudring tapped for 8-32’s...that would be great lol

years ago, I had an inspector tell me that if everything is folded in neatly, and there is obviously plenty of space for the devices or fixture connections, he wasn't going to be bothered counting conductors. which was a relief because the box he was looking at was at its maximum conductor fill.

It looks like your ground pigtail may actually be #12 AWG so wouldn't that push you over the 6.0 CU INCH limit or does the pigtail not get counted? Seem odd that because of the regs, using #12-2 wouldn't be allowed even though the biggest issue with those boxes is fitting the wire nuts into that tiny space and not the air gap around the wires. Those flat Wago lever-nuts sure are a big help and yet they're not required.
@jamesalvin57352 жыл бұрын
You're right that the pigtail is #12, but 314.16(B)(5) says that the calculation shall be based on the largest conductor "entering" the box, which would be the bare #14. The "entering" distinction was added in the 2020 edition, so if you're using an older edition, that would explain your confusion 🤙

it means you count the first four grounding conductors as 1 conductor count of the size of the biggest. say you have a #12, a #14, and a #18, like in his example, you would count them all as 1 #12. if you had a multigang switch box with 6 #14 grounding conductors, you would count the first 4 as one #14, and then count the next two as two quarters of a conductor count,
