This study guide is organized to match the way topics appear on the Washington (06) Limited Energy Electrical 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 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.
This set of questions applies to the following subclasses of PSI exams: Administrator, Master Electrician & Electrician.
Questions are sourced from the NEC and Washington statutes shown in the allowed book section below and match the subjects shown in the PSI bulletin.
Additional bonus questions are included from Ugly’s Electrical References.
Study material will include sample questions for “Major Load Calculations” and “General Trade Knowledge” from Ugly's References and Chapter 9 Tables of the NEC.
All study materials are delivered electronically for instant access after purchase and are provided as ZIP archives containing standard US letter-size PDF files. For reliable access, files should be downloaded and extracted on a computer, tablet or printed for offline study.
NOTICE: For the calculations portion of the examination, Annex D in the NEC is a good source of examples. There are no questions from Annex D contained in our set of questions. Additionally, we give you a list of questions in our answer key that may apply to calculations. You will want to purchase a separate book that covers calculations in more depth like the one we recommend in the “Additional Allowed” section below.
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.
All responsibilities and scope of work specifications are detailed in statute section WAC 296-46B-920 accessed from the button below.
The books below must have original binding with no written notes in margins.
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.
