I would like to know why pigtails are not included in the volume count for outlet receptacle boxes.
I recently upgraded to a two way outlet and had a total of four 14/2 wires coming into the box and stay under four wires per wire nut I used pigtails. This ended up leading to quite a few pigtails in the box but based on NEC codes I’ve seen people quote on here pigtails aren’t added to the count and I don’t understand why. It definitely can crowd the box!
Edit 1/8/2020 9:51pm: For example my situation is as follows: I’m looking at new handbook and maybe getting confused. I thought the point of this was to ensure there was enough space ( conductors to space ratio) for heat related issues. In my case , The outlet box is 38 cubic inches. I have 3 14/2 wires going in and 1 14/3 wire going in. I have two receptacle outlets for it. I wired the outlets in parallel instead of daisy chain (I created daisy chain to limit to a max of four wires in a wire nut). In total I have 6 black, 7 white , 1 red, and 7 ground. I had a total of 7 ideas protwist wire nuts used. So what does that put me at for total volume then?
