There are others re: Mike Holt's Forum, I've accessed that site 1000's of times for guidance.
Also entertaining; a typical 'safety' sticker on 80's era Asian import machines "Electrical System and Components Approved by Los Angeles City Electrical Code"; except didn't specify which particular Los Angeles they refer to. Recall the Mandarin Oranges "Made in USA'? Turns out they named a city 'USA'.

A peek in the panel didn't reinforce the sticker. Look in panels of an old Kearney Trecker, Cincinnati, DeVlieg, Lodge & Shipley, American Tool Works, Cleereman...THOSE ARE COMPONENTS! THAT'S WIRING!
Now, in my estimation the most stringent codes are New York for fire and electrical, electrical, building and plumbing in Los Angeles. They each expand the NEC, UPC, NFPA etc, and models for so many municipalities it isn't funny.
