Mike Holt reviews from electricians (review 4)

What electricians actually say about Mike Holt

Spend any time in the trade and Mike Holt's name comes up. His books sit on supply house counters, his videos play on lunch breaks, and his courses show up on continuing education rosters in nearly every state. The reviews from working electricians are mostly positive, but not without caveats.

The short version: Holt is excellent for learning the code. He is less useful when you are 18 feet up a ladder trying to figure out if a junction box needs a bonding jumper under NEC 250.148. That gap is where most of the criticism lives.

Where Mike Holt earns the praise

The teaching is the strongest part. Holt breaks down NEC articles in plain language, with diagrams that actually match how the work gets installed. Apprentices preparing for the journeyman exam tend to rate his prep materials at the top of the pile, and journeymen studying for the master's exam say the same.

Common points electricians bring up in reviews:

• Clear explanations of grounding and bonding (NEC Article 250), which is where most exam takers lose points.
• Solid coverage of branch circuit calculations under NEC 220 with worked examples.
• Illustrations that show the conductor, the conduit, and the box, not just abstract diagrams.
• Updates that track each new code cycle, including the 2023 changes to GFCI requirements in NEC 210.8.

For passing a test or studying a specific article in depth, the material holds up. Most of the negative reviews are not about the teaching quality.

Where the complaints come in

The biggest complaint is format. The textbooks are heavy, the video courses are long, and the search tools on the digital products are limited. If you already know what you are looking for, finding it can take longer than just opening the NEC handbook.

One commercial foreman in Ohio put it this way in a forum thread:

I love Mike Holt for studying at the kitchen table. On the job I need an answer in 30 seconds, not a 12 minute video on the theory of voltage drop.

That is a recurring theme. The depth that makes Holt great for learning becomes a liability when you are billing time and the inspector is waiting. Reviews from service electricians and troubleshooters are noticeably cooler than reviews from apprentices and exam takers.

Price and what you actually get

Holt's full code library and exam prep bundles run several hundred dollars. The individual books are reasonable, but the video courses and online programs add up fast. For a non union electrician paying out of pocket, that is real money.

What is included varies by package, but typically:

1. NEC code book (sold separately or bundled).
2. Holt's annotated textbooks for specific articles.
3. Video instruction with practice questions.
4. Online access for a limited subscription period, usually one or two years.

The subscription model bothers some reviewers. Once your access expires, the digital tools go dark. The physical books you keep, but they get outdated each code cycle. That is not unique to Holt, but it shows up in negative reviews often enough to mention.

Study tool versus field tool

This is the distinction most reviewers miss. Mike Holt built a study and education brand. He did not build a field reference. The two jobs are different, and the tool that wins one usually loses the other.

A study tool wants depth, narrative, and worked examples. A field tool wants speed, accuracy, and a way to get to the exact subsection of NEC 314.16(B)(1) for box fill calculations without scrolling through three chapters of context. Most electricians end up using both, one for the truck and one for the kitchen table.

If you are studying for an exam, buy Holt. If you are running service calls, you need something faster on your phone.

That advice shows up in some form in nearly every honest review thread on Reddit's r/electricians and on Mike Holt's own forum.

The bottom line from the field

Mike Holt is the gold standard for code education. The reviews back that up. If you are preparing for a journeyman or master's exam, his materials are worth the price and the time.

The criticism is not that the product is bad. It is that it is built for one job, and electricians have two jobs. Studying the code and applying the code on a live panel are different problems. Holt solves the first one well. For the second one, most electricians keep a code book in the truck and a phone reference in their pocket, because flipping through 800 pages while standing in an attic is not a workflow anyone defends.

That is the honest read from working electricians. Holt is excellent at what it was designed to do. Just know what it was designed to do before you spend the money.
