Bob, 310.15(B)(2) doesn't say anything about exempting "... single conductors or multiconductor cables are stacked or bundled longer than 600 mm (24 in.) without maintaining spacing and are not installed in raceways..." when it points you to table 310.15(B)(2)(a).
OK I see what your getting at. 
That aside how many home panels have the room for a 24" or longer bundle?

No worries, it happens to all of us.
I picked up on it as I could not remember a 300.34 at all which made me go look at it.

Well I’m fixin’ to put a QO130 (SqD type 9 can) in my house. That is 29" tall so it would be easy to bundle 24" of wire in there but I did say this is more likely in a commercial panel.
The 10, 11 and 12 cans have plenty of room.
I will have splices in there too 
That's why I went for the bigger enclosure. I hope I can make it pretty enough to post a picture here. Now if I can just find the time. I wonder if Santa will bring me some minutes.

I almost hate to do this but…
Unless the panel labeling indicates the neutrals can connect to the equipment ground bar we may be looking at a violation.
From what I can see that grounding bar on the left is screwed to the steel enclosure and has no bus bar or conductor connecting it to the neutral bar on the right.
If that is true the panels enclosure is being used as a neutral conductor which is a violation.

I like to loop a 4ga solid (or whatever 250.66 calls for) through all ground busses before I start building a service panel. I know that screw is legal but I like wire.
