This study guide is organized to match the way topics appear on the Nevada (C-2F) Residential Wiring 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, ohms law and topics that commonly appear on the electrical exam.
Sample questions are sourced from the National Electrical Code (NEC) and Ugly's Electrical References. A subject category index mapped to question numbers is included with the answer key.
Bookmarks have been added to help the user randomly jump to specific questions related to NEC Articles in the code.

We recommend that you purchase one of the two NEC index 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 subjects covered in the exam and are far more detailed than the index at the end of the code book.
