Mike Holt 30-day review (review 3)

Thirty days with Mike Holt's training materials and code apps. I bought the package, used it on real jobs, and timed how often it actually answered what I needed in the field. Here's the honest read from someone pulling wire, not someone writing curriculum.

What I Bought and How I Used It

I picked up the Understanding the NEC Volume 1 and Volume 2 package, plus the digital code app with the illustrated graphics. Used it for thirty days across a mix of resi service changes, a small commercial tenant fit-out, and two pool bonding inspections. Phone in pocket, tablet in the truck, books on the bench at home.

The goal wasn't to learn the code from scratch. I've been licensed twelve years. The goal was to see if Mike Holt's stuff replaces my dog-eared NEC handbook and the three apps already on my phone when I'm standing in an attic at 2pm trying to confirm a clearance.

• Resi panel swaps: 14 jobs
• Commercial branch circuit work: 6 jobs
• Pool and spa bonding: 2 jobs
• Inspector callbacks: 3 (all resolved with a code citation)

The Illustrations Are the Real Win

Mike Holt's graphics for working space, NEC 110.26, and grounding electrode systems under NEC 250.50 are genuinely the clearest visual explanations I've seen. When I had a green apprentice trying to understand why the 3-foot working space matters in front of a panel, I pulled up the illustration and he got it in 30 seconds. The book had been getting blank stares for a week.

For pool bonding under NEC 680.26, the equipotential bonding diagrams saved me an argument with a pool contractor who swore the perimeter wire wasn't required. Pulled up the graphic, showed him the 18 inch to 36 inch zone, done. Inspector showed up two days later, signed off without a word.

If you train apprentices, the Volume 1 illustrations alone are worth the price. Print the working space and grounding diagrams, laminate them, stick them in the truck.

Where It Falls Short in the Field

Mike Holt's material is built for learning and exam prep. It's not built for the moment you're on a roof and need to know if NEC 690.12 rapid shutdown applies to a microinverter system installed in 2019. The search in the app is slow, the results are organized for study flow, not lookup speed, and you're often three taps deep before you find the actual code text.

I timed it. Average time from "I need an answer" to "I have the citation" was 47 seconds on the Mike Holt app. On my NEC handbook PDF with bookmarks it was 22 seconds. On Ask BONBON it was 9 seconds, but I'm biased because I built it after getting tired of exactly this problem.

• Search prioritizes course content over raw code text
• No quick offline citation lookup by article number
• Tables are images, not searchable text
• Cross-references require navigating back to the table of contents

The Continuing Education Side

Where Mike Holt absolutely earns the money is the 2023 code change videos and the CEU courses. I knocked out 8 hours of state-required CE in two evenings. The instructor walks through every significant change with the actual code language on screen, which is exactly how a working electrician wants to absorb updates.

The changes to NEC 210.8(F) for outdoor outlets, the expansion of GFCI requirements, and the new emergency disconnect rules under NEC 230.85 were all covered with practical examples. I came out understanding why the changes happened, not just memorizing them for a test.

If you need CE hours and you actually want to learn something instead of just clicking through a slideshow, Mike Holt's video courses are worth twice what they charge.

Price vs. What You Actually Get

The full Understanding the NEC package runs around $400 for the books and another $80 to $150 for various app subscriptions and code change material. For a journeyman or master who trains people, that's a reasonable annual investment. For someone who just needs to look up code on a job, it's overkill and slow.

Compare that to keeping a current NEC handbook on your phone (free with the right setup), a fast lookup app, and one good CE provider per cycle. You can cover the same ground for under $200 and get answers faster in the field.

1. Apprentice or training role: buy the full package
2. Working journeyman who wants strong CE: buy the videos, skip the books
3. Field-only lookup needs: skip Mike Holt, use a dedicated code reference tool

Final Verdict After 30 Days

Mike Holt's stuff is the best teaching material in the trade. Nothing else explains the why behind a code section as clearly. The illustrations, the video instruction, and the structured curriculum are unmatched if your goal is to learn or to teach.

It is not the right tool for fast field lookup. The product was built to help you understand the code, and it does that beautifully. But when you're 20 feet up a ladder and the GC is asking why the receptacle has to be GFCI under NEC 210.8(B)(8), you need a citation in 10 seconds, not a curriculum. Use Mike Holt for the classroom and the truck cab at the end of the day. Use something else for the moment of truth.
