Taking practice exams is the best way to learn your way around the National Electrical Codebook.  This 300 question practice exam is a code cannon that randomly fires off questions at you without a time limit.  It simply allows you to go through each question at your own pace and get practice flipping back and forth through the codebook.  With 300 questions you’re sure to get a ton of practice trying to find information everywhere throughout the book.

These 300 questions are taken directly from the 2020 National Electrical Code.  Questions are displayed randomly.  When you miss an answer there are code references and explanations that will tell you how to get the answer correct the next time.
