Mike Holt 1-year review (review 5)

One Year With Mike Holt: The Honest Take

Bought into Mike Holt's program last spring. Continuing ed, code books, the Understanding the NEC video library, plus the app. Twelve months later, I've run service calls, pulled commercial branch circuits, sat through an inspection that hinged on 250.122(B), and used the material for all of it. Here's what held up and what didn't.

Short version: the teaching is excellent for sit-down learning. The field experience is mediocre. If you're studying for a license exam or trying to actually understand grounding theory, Mike Holt is hard to beat. If you're on a ladder at 2pm trying to figure out box fill for a 4-square with three 12-2s and a switch leg, you'll be flipping pages.

What Mike Holt Does Well

The graphics and explanations are the gold standard. Bonding versus grounding in 250 finally clicked watching his videos, and the way he walks through 310.16 ampacity tables with the correction and adjustment factors is cleaner than anything else out there. For exam prep, especially journeyman and master tests, the practice questions track real test logic.

His take on 690 and 705 for solar interconnections saved me on a job last fall where the AHJ wanted load-side tap calcs spelled out. I had the reference, I had the math, the inspector signed off. That's worth real money.

• Strong on theory: grounding, bonding, GFCI/AFCI logic, transformer secondary protection
• Excellent exam prep for licensing, especially the 2023 cycle
• Continuing education credits accepted in most states I checked
• Calculation walkthroughs (Article 220, 230, 250) are best in class

Where It Falls Short in the Field

Here's the friction. The Mike Holt app is essentially a digital code book with bookmarks and search. Search is okay. It is not fast. When you're standing in an attic with one bar of LTE, typing "210.8" and waiting for the article to render, then scrolling to find (A)(7) for sinks, you're losing daylight. The PDF based viewer wasn't built for one-handed lookup.

Cross referencing is the bigger issue. Half of NEC compliance is one article pointing to another. 210.8(F) sends you to consider outdoor receptacles, which loops back to 406.9(B) for weather resistant requirements, which references 110.3(B) for listed equipment. Mike Holt's materials explain these links beautifully in a classroom. In the field, you're tab hopping.

Real tip: if you use Mike Holt PDFs on your phone, pre-download the chapters you hit most (Article 210, 220, 250, 300, 314) before you leave the truck. Reception in basements and mechanical rooms will eat you alive otherwise.

The Price Question

I spent roughly $600 over the year between the comprehensive library, the code book, and a continuing ed bundle. That's not nothing for a one man shop. The continuing ed alone is competitive with what the union halls charge, and the depth is better than most live classes I've sat through.

But I want to be straight: a lot of guys on my crew use the free Mike Holt YouTube content and a $60 NEC handbook and get 80% of the value. The paid tier earns its keep mainly if you're chasing a license, doing PV or commercial work where the calc-heavy articles matter, or you genuinely enjoy studying code. If you just need to look stuff up on a job, the ROI is thinner.

Mike Holt vs. Field Reference Apps

This is where the comparison gets honest. Mike Holt is a teaching company. The app is an extension of the textbook business. Tools built specifically for code lookup on the job, including Ask BONBON, are solving a different problem: how fast can you find 314.16(B)(1) when a homeowner is staring at you.

I still keep Mike Holt for the deep dives. Sunday mornings, coffee, working through a chapter. That's where it shines. But for the truck and the toolbelt, I want something that handles three things faster than flipping a paper book or a PDF:

1. Box fill and conduit fill calcs without a calculator and Chapter 9 tables
2. GFCI/AFCI requirements by location, current 2023 cycle, including the 210.8(F) outdoor changes
3. Equipment grounding conductor sizing per 250.122 with parallel conductor adjustments

Mike Holt teaches you why those rules exist. That matters. But on Tuesday at 3pm with an inspector waiting, knowing why doesn't help if you can't surface the citation in fifteen seconds.

The Verdict After 12 Months

Keep Mike Holt for learning. Use a purpose built reference for the field. They're not actually competitors, even though guys treat them that way. One is a teacher. One is a tool.

If I had to pick one for a brand new apprentice, I'd say Mike Holt YouTube plus the printed handbook for the first two years. After that, they need a fast lookup tool because the job moves faster than book pages turn.

Would I renew? The continuing ed portion, yes, automatically. The full library, probably not for year two. I've absorbed what I needed from the calc heavy chapters, and the videos don't change much cycle to cycle except for the actual code updates. For 2026 cycle prep, I'll buy the update materials when they release and skip the rest.

Bottom line: Mike Holt earned its reputation. It's also not the answer to every problem in this trade, and pretending otherwise sells working electricians short.
