Thanks all, for the replies.
Had a Non-Compliance issue in Fullerton just recently, where I was helping my Father do a Residential Service upgrade.
I left the GEC's Insulation Black, and that was written up as the only correction. AHJ wanted Green, so I taped them Green and all is OK now.
Not something to start an arguement or debate over, but I would have liked to ask for an article quote, just to verify we were all on the same Hz
