Mike Holt 30-day review (review 2)

Thirty days with Mike Holt's training materials. I'm a journeyman pulling residential and light commercial in the field, and I wanted to know if his stuff actually saves time on the truck or if it's just exam prep dressed up as a reference.

Short version: it's exam prep dressed up as a reference. That's not an insult. It's just what it is.

What Mike Holt actually is

Mike Holt Enterprises sells NEC training. Books, video courses, illustrated graphics, exam prep bundles. The flagship product is the Understanding the NEC series, which walks you through articles with color illustrations and plain-language explanations. There's also a code app, but the bulk of the value is in the printed and video content.

If you're sitting for a journeyman or master exam, this stuff is gold. The illustrations alone are worth the price because they show you what a code section looks like instead of just quoting it. Article 250 grounding makes sense after you see his diagrams. Article 310 conductor sizing clicks when you watch him work a load calc on video.

Tip: if you're studying for an exam, buy the illustrated book before the video set. The book is faster to reference, and the videos repeat what's in the book about 80 percent of the time.

On the truck, day to day

This is where it falls apart for me. I'm not studying. I'm in a crawl space at 2pm trying to figure out if a 20-amp circuit feeding a kitchen island countertop receptacle needs GFCI, AFCI, or both, and whether the disconnect requirements in NEC 422.31 apply to the dishwasher I just pulled.

Mike Holt's app and books are organized like a textbook. Chapter, then article, then commentary. That's great for learning. It's slow when you need an answer in 30 seconds. I found myself flipping past three pages of explanation to get to the actual code text, which I could have read in the NEC handbook in half the time.

The search in the app works, but it searches Mike's commentary, not just the code. So a search for "GFCI kitchen" returns six training videos and four article summaries before it shows you NEC 210.8(A)(6).

What it gets right

Credit where it's due. A few things Mike Holt does better than anyone else:

• Grounding and bonding. Article 250 is the most confusing part of the code, and his illustrations are the clearest explanation I've seen in 12 years.
• Load calculations. The worked examples in his calc book cover real scenarios, not just textbook problems.
• Code change summaries between cycles. When the 2023 NEC dropped, his change-tracking material was faster to digest than the official ROC.
• Service and feeder sizing. Article 215 and 230 examples are well done.

If you're a first-year apprentice or you're switching from commercial to residential and need to ramp on grounding fast, the cost is justified.

What it gets wrong for field use

The real problem is speed and density. When I'm troubleshooting a tripping AFCI on a bedroom branch circuit, I don't need a 15-minute video. I need to know:

1. What's the code citation? NEC 210.12(A).
2. What are the exceptions? Listed in 210.12(B) and (C).
3. Does this install fall under one of them? Yes or no.

Mike Holt's material answers question 1 eventually. Questions 2 and 3 require flipping, scrubbing, or skimming. On a service call where the homeowner is watching the clock, that's a problem.

The other thing: it's a paid ecosystem. The illustrated book is around 200 dollars. The video set is more. If you want the full Understanding the NEC bundle plus the calc book and the change tracker, you're looking at 600 to 800 dollars depending on which edition cycle you buy into. That's fine for a one-time exam push. It's a lot for ongoing field reference when the actual NEC PDF from NFPA is free to read online.

Who should buy it

Honest breakdown after 30 days:

• Apprentices and exam candidates: yes, buy it. Worth every dollar.
• Instructors and CE providers: yes, the illustrations and slides save prep time.
• Inspectors who need to explain a citation to a contractor in the field: maybe, the visuals help in disputes.
• Working journeymen and masters who already passed the exam: probably not. You already know the code. You need lookup speed, not commentary.

Tip: if you're past your exam and just want code answers fast, the NFPA's free read-only NEC plus a good searchable reference will serve you better than a 600-dollar training bundle.

Bottom line after 30 days

Mike Holt is the best NEC teacher in the industry. That's a different job than being the best NEC reference for a working electrician. His material is built for the classroom and the exam room, and it shows.

I'll keep my illustrated grounding book on the shelf because Article 250 still trips me up sometimes. Everything else I'm reaching for something faster on the truck. If your day involves more troubleshooting than studying, your money is better spent elsewhere.
