Tom Henry's Key Word Index, 2023, Tom Henry
Buy at Amazon

We recommend that you purchase one of the reference books above to study for your exam.  Each book is a comprehensive subject index to the NEC.  They provide an even faster way to look up answers in the code and are far more detailed than the index at the end of the code book.

2.
Ugly's Electrical References, 2020 or 2023, Charles Miller 
Buy at Amazon
3.
Practical Calculations for Electricians, 2023, Ray Holder
Buy at Amazon

Reference #2 above contains practical applications of the NEC such as Ohm‘s Law, series/parallel circuits, voltage drop, load calculations, motor phases, impedance, inductance and math formulas you are expected to know.  “Basic Knowledge” is covered in the exam but detailed subjects are assumed and not specifically called out in the bulletin.

A "calculations" book where you can drill yourself repeatedly is always a good way to remember the most basic math procedures.  Generally, you won't have time during an exam to search for these procedures in a book.
