You ever go book shopping, and just read the preface? , well sales will pick up on the 2002 ....
First of all, we gotta say "luminaire" , which i suspect is french for "thing on the cieling", but i'm not sure. Apparently this change is made so many times in the 2002, from the two worded "lighting fixture" that stocks will likely drop in ink.
Art 90-1-d introdues "retroactivity" a 6 sylable beast meaning "I liked it yesterday, but not now"
Art 90-2 is a turf war, utilities have been doing retro's and other usually contracted work for years, NEC exempt.
90-4 is a "special permission" goodie that allows the AHJ the space he/she should have, hats off to Fred H.
Art 80 defines the AHJ. It's wordy, long , and reads like the golden goose for the legal community to really make a living off.
