The books listed below are NOT allowed at the exam location
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.
Ugly's References contain practical applications of the NEC such as Ohm‘s Law, series/parallel circuits, voltage drop, load calculations, motor phases, impediance, inductance and math formulas you are expected to know. The "Basic Knowledge" covered in the exam is assumed and sometimes not listed as a subject. This book also covers subjects listed as "Calculations and Theory".
A practice exam is currently NOT AVAILABLE
