Welcome Knox!
As you study & learn, be sure to ask here any questions which arise. People here are very helpful!
Heck, I've been a master since 1976 and work industrial and high voltage distribution. No residential or commercial other than friend and family freebies, so I don't keep up with interpretations to section changes. When I ask a question about a current code section for dwelling units, lots of people jump in & cheerfully help. This is a nice place to learn!
