In addition to the trade-specific examination, you may be required to pass the Business and Law Exam offered by PSI or take an "approved" Business and Law course
The bulletin calls out an NEC version with "SC modifications" that can be found on the NFPA web site. This is false. NFPA does not provide localized versions of the code.
If you want to see the exact code modifications to the NEC (only effects two sections: 90 & 210), you'll have to start on this web page: Building Codes Council and work your way up from the 2005 version which is where they started. Where it says "Continued", go to the previous version to find the change.
QUESTION: “What is the difference between the National Electrical Code (NEC) and the NEC Handbook?”. The Handbook has the same content as the NEC book with additional drawings and explainations inserted.
The Handbook was designed for engineers and inspectors. The typical exam candidate should not use it as a prefered reference unless they are using it for inspection jobs in their day-to-day work.
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".
Sample questions are based on the PSI publication titled “29 CFR PART 1926 Selections, as of June 2013” (hightlighted in green above).
This file contains approx. 800 sample questions.
REMINDER: PSI uses this book for many exams they offer. Not all sections of this code will apply to your exam.
