Well, at least they wrote a disclaimer about the black, red and blue wires being 277.
They forgot to write: "This box is messy and over crowded and contains code violations"
Is 120 and 277 mixed in this box?

Where's the problem? A simple calculation reveals---
1) There are (3) 1/2" KOs. on each side of the box
2) There are 4 sides
3) That makes (12) 1/2" KOs
4) 1/2" thinwall is good for (9) #12 THWN
5) 9 x 12 = 108 #12s allowed in that box
6) I think there's room for 80 more.

Hmmm, is it ok to put his 277v lighting in with what I'm assuming may be 120v circuits? At least they are warning the next guy. And hopefully he used 12 solid to cut them short, just so they would fit a little better.
12 stranded seems much easier to get into boxes in general, yet to be a packer of sorts, and forget the extension ring at the shop doesn't help either.

Non Linear Load.
200.6 D states:
"Where conductors of different systems are installed in the same raceway, cable, box, auxiliary gutter, or other type of enclosure, one system grounded conductor, if required, shall have an outer covering conforming to 200.6(A) or 200.6(B). Each other system grounded conductor shall have an outer covering of white with a readily distinguishable, different colored stripe other than green running along the insulation, or shall have other and different means of identification as allowed by 200.6(A) or (B) that will distinguish each system grounded conductor." NEC 2002
I wonder which was the neutral, Black, red or blue?

Messy or not... wouldn't a simple extension ring address the box fill issue?
