    2020 Nec-- Equipment Grounding Conductor & Box Fill

    This one my cause some issues with conductor fill in multi gang boxes



    314.16(B)(5) Equipment Grounding Conductor Fill.

    Where up to four equipment grounding conductors or equipment bonding jumpers enter a box, a single volume allowance in accordance with Table 314.16(B) shall be made based on the largest equipment grounding conductor or equipment bonding jumper entering the box. A 1∕ 4 volume allowance shall be made for each additional equipment grounding conductor or equipment bonding jumper that enters the box, based on the largest equipment grounding conductor or equipment bonding conductor.

    Thats a change that will be missed by many... and will require all the box fill test questions to be rewritten!

        Are we the point where people just need to come up with ridiculous code changes and the CMP accepts them with little or no substaniation? Really, more than 4 each counts as 1/4, this is starting to sound like a joke.

          Yes, we are. It's a steady decline. I mean it when I say we need to go to a ten year code cycle.

            The constant micro-tweaking is very annoying, more often than not unsubstantiated, and not in line with the real purpose of the NEC which is safety.

              It does appear to be bordering on the insane.

                That's the general course that the NEC is taking. What happened to these CMP's?

                  They are well meaning I'm sure, but there is just not enough real problems out there any more so we are left with these nick picky changes because there is nothing left to act on.
