after 25 years of requiring this...amen...

"lettering on their receptacle plates in the living room." I believe the requirement is at the panelboard & Switchboard & not at the final wiring device or eqiupment, except for health care facilities- 517-30 (E).

I love the education strings you are doing, but this one in particular I feel you needed more work on. Twice you mention four (4) reels of #1/0 or #1 to feed panels (brown, orange, yellow, white). You also mention the cost of reeling it on to one (1) reel. Try reeling it to one reel some time and you won't like the tangle you are left with, especially in long pulls. With all the 'grounding' education you have done, you went right through the video without the mention of the grounding conductor added to the reel lineup.

With the new arc flash requirements being required I have a feeling more labeling will be done so future wearing of arc flash gear will be avoided

On larger projects we add the location of the 'up-stream' protective device to our labels for the convience of the Owner. This is not a code requirement of course.

Wow learn something new every day. I never knew this was a actual code requirement, just thought that it was a good practice.

This has got to be the most ignored electrical rule!

Hey Mike, What 110.22 doesn't say is that the circuit directory included with the panel isn't big enough to write all that clear,evident,and specific. It works good in industrial and commercial. you can label device plates etc. But, most home owners don't like PL2 CKT12 lettering on their receptacle plates in the living room. Moat inspectors around here are good about it, as long as you make the effort. But, if they enforced the letter of the code, you'd sure have to do a lot of writing and that directory would be the size of a roadmap

This section and I have been at odds with each other for some time.

Not that I mind identifying breakers; indeed, I really like the practice. I even have gone so far as to apply printed labels directly on the breakers - handy when the cover is off the panel!

The trouble has come from that part of the code section that says the identification shall be in a 'directory' mounted on the cover. Some have insisted that an identification upon, or next to a breaker is not enough ... you MUST use that little white card.

In the current code cycle, I made a proposal ... to change the wording to specifically allow my practice. The response of the code panel? "No need to - the code already allows for this."

I suppose it comes down to that a 'directory' is. For those who wish to see the code panel's exact ruling, it is found in the 2008 ROP.

I'm not a fan of this, either. I don't think it works well in many cases. I prefer to rotate circuit numbers on multi-wire branch circuits when going around a room (1, 3, 5, 1, 3, 5, etc.) so that adjacent receptacles aren't on the same leg. How do you write that in a directory? "Every third receptacle in room 101, starting with the second receptacle from the door, going in a clockwise direction." There's no provision to use tags on device plates (and my wife would never allow them in her kitchen), and even if there was there's no guarantee that the device plates won't be replaced with unlabeled plates or that plates won't get swapped? And how do you identify rooms? Is "Sam's office" OK? What about if he relocates? "Room 101" is only meaningful if the room itself is really labeled Room 101. "East receptacles" doesn't do any good if you have a poor sense of direction.

This is great in theory, but not very workable in practice.
