Timed on the published format, and it tells you where your time went. Original questions written for this site.

Minnesota reads the 2026 book

The Minnesota examinations follow the 2026 National Electrical Code from 8 September 2026, and the state adopted the same 2026 edition for permits filed on or after 17 August 2026, without Minnesota amendments. This page holds no table values, and the sections it names are the 2026 numbers.

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.

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 Minnesota 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.

If your notes still say 2023

The 2023 to 2026 section crosswalk maps every section that moved, both directions, $29 once.

Every rule here is cited to the section it comes from, and corrections are logged in public with the date. This is study material rather than electrical advice, and it does not replace your own code book or your inspector.

The Minnesota examinations are open book on a book the department hands you. DLI provides the National Electrical Code in soft cover with no tabs or other aids, allows a laws and rules booklet and a basic calculator, and allows no other materials or electronic devices in the building. The questions follow the 2026 edition from 8 September 2026, and 17 August 2026 is the permit date rather than the exam date.

All practice questions are original. They are not actual exam questions.
