How about 230.8, this is one item that I see missing in a lot of installations. Don't forget 300.5(G) and 300.7(A).
With that installation being installed 25 years ago, I can see the size of the neutral conductor, but with todays concerns for neutral capacity, I doubt you will see neutrals that size.
BTW - for a 25 year old installation, it looks to be in very fine shape. That is why Capt Al's infrared inspection is so important.
