NOTE: The study material we are offering for this exam will NOT include sample questions for “Major Load Calculations” and/or “General Trade Knowledge” specifically because they can not be created from code books or statutes. This subject matter CAN be extracted from Ugly's Reference shown below and Chapter 9 of the NEC.
We highly 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.
The book above contains 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".
Questions are sourced from the NEC and Washington statutes shown above.
An answer key with detailed code sub-section references is included.
The approx. number of practice questions in this package: 1,625
Additional bonus questions (60) are included from Ugly‘s Electrical Reference and the American Electricians‘ Handbook.
