NEC Fundamentals

Learn to navigate the National Electrical Code the way a journeyman does on a jobsite: the three-year revision cycle, NEC chapter structure, Table 310.16 ampacity and the termination-temperature rule, 210.8 GFCI and 210.12 AFCI locations, Article 250 grounding and bonding, 110.26 working space, and 314.16 box fill. Codebook Navigation teaches the lookup skill, then residential wiring and service panel guides give you the real circuits the code is written around.
