Practice exam
Timed on the published format, and it tells you where your time went. Original questions written for this site.
The North Carolina examinations are open book on the 2020 National Electrical Code, and the state enforces the 2020 edition with its own amendments. This page holds no table values, but the sections it names are the 2026 numbers, so check them against your own 2020 copy.
The article level moves are concentrated at the two ends of the book: Chapter 1 took in load calculations from Article 220 and energy management from Article 750, and the limited energy and communications material was rebuilt across the 720s. Ampacity, overcurrent, grounding, motors and boxes kept their articles, and Chapter 9 is still the tables. What we hold on the moves compares the 2026 edition with the 2023 one, and the record does not reach a 2020 book, so it cannot tell you what any of these numbers is in the edition North Carolina tests on. Look each one up in your own copy.
Before you start
Have your code book open. Every question here is answerable with it, and working without it trains a skill you will not use in the exam room.
Questions supply any looked-up value as given data. What is being tested is the method, which is where the marks actually go.
Exam simulation uses this site's own mix, roughly seven knowledge questions to every three calculations, and clocks you at the pace the North Carolina paper sets. It withholds every answer until you submit, the way the real one does, and gives you a review screen first. Practice deliberately leans the other way, toward the calculation questions, because those are the slowest ones to work. It explains each question the moment you answer it.
