This study guide is organized to match the way topics appear on the Residential Electrician exam. Here is what is included in your download:
Use these questions alongside your National Electrical Code (NEC) book. Read a section of the book, then work through the related practice questions to check your understanding.
Each sample question includes a reference to the NEC article number where the subject is discussed. This helps you quickly review why the correct answer is right and reinforces the process of looking up information efficiently — a key skill for an open-book exam.
Bookmarks have been added throughout the study guide to help you:
Use the additional questions drawn from Ugly’s Electrical References to strengthen your coverage of general theory, Ohm’s Law and topics that commonly appear on the electrical exam.
Sample exam questions are sourced from the National Electrical Code (NEC), Ugly’s Electrical References.
Get instant access to the Residential Electrician Exam Study Guide and start practicing with exam-style questions. Use the included code references to build speed, accuracy, and confidence for an open-book exam.
All study materials are delivered electronically for instant access after purchase and are provided as ZIP archives containing standard US letter-size PDF files.
The official exam bulletin is published and maintained by PSI. Bulletin content (subjects covered in the exam) and file names for PDFs change regularly. Always set your “favorite” or “bookmark” to the landing page we have linked above. Candidates should always review the current exam information on the PSI website before applying or testing.
QUESTION: "What is the difference between the National Electrical Code (NEC) and the Handbook version?". As far as the actual NEC code quoted in the text... it's the same.
The NEC Handbook has additional diagrams, graphics and explanations inserted into the text (adding more pages and raising the price). It was designed for engineers and inspectors. The typical exam candidate should not use it as a preferred reference.
NOTE: We do not recommend buying older (out-of-print) editions of Ugly's References as suggested in the exam bulletin which tend to be more expensive and harder to find.
The books listed below may be allowed at the exam location as long as they have the original binding and no written notes. Read your exam bulletin and look for the "What to bring" or "What is allowed" statement for specific restrictions.
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.
