Mike Holt reviews from electricians (review 6)

Mike Holt's name comes up every time electricians talk about code training. His videos, books, and seminars have trained a generation of us. But how does his stuff hold up when you're standing on a ladder with a hot panel open and need an answer in fifteen seconds? I've used Mike Holt materials for years. Here's the honest take from the field.

What Mike Holt Does Right

The man knows the code. His Understanding the NEC books are some of the clearest explanations of grounding and bonding you'll find anywhere. NEC 250 is a swamp, and Holt drains it. His illustrations of fault current paths, the difference between grounded conductors and grounding electrode conductors, and why we bond at the service... that stuff sticks.

His Continuing Education program is solid for license renewal. Most states accept it, the courses are well-organized, and the instructors actually answer questions. If you need CEUs and want to come out the other side knowing more than when you went in, Holt delivers.

• Strong on grounding and bonding (NEC 250)
• Clear treatment of conductor sizing and ampacity (NEC 310)
• Good GFCI and AFCI coverage including NEC 210.8(A) and 210.12
• State-approved CEU paths for license renewal

Where It Falls Short on the Job

Holt's content is built for studying, not for jobsite lookups. The videos are 20 to 45 minutes long. The books are 400 plus pages. When you're on a service call and the homeowner's watching you, you don't have time to scrub through a chapter to find whether a kitchen island receptacle needs GFCI protection (it does, NEC 210.8(A)(6), and yes that includes the ones below the countertop now).

The search inside his digital products is also weak. Searching "tamper resistant" pulls up every video where he mentions the phrase, not the specific code section that answers your question. That's fine for a classroom. It's useless on a roof.

Field tip: keep Holt's grounding book in the truck for studying between calls, but don't try to use it as a live reference. You'll burn an hour and still not find what you need.

Price and Value

Mike Holt materials are not cheap. A full Understanding the NEC bundle runs several hundred dollars. The exam prep packages for journeyman and master are more. For an apprentice or a first-year journeyman, that's real money.

If you're prepping for an exam, the price is justified. The pass rates speak for themselves. If you just need a code reference for daily work, you're paying for a lot of training material you'll never open again after the test.

1. Exam prep: worth it, especially the master's package
2. CEUs: worth it if your state accepts the course
3. Daily code lookup: not what it's built for
4. Quick refresh on a specific article: too slow

How It Compares to Other Tools

Holt is in a different lane than the NFPA's NEC Handbook or a code lookup app. The Handbook gives you the code text plus commentary, organized exactly like the code itself. That's faster for lookups but assumes you already understand the structure. Holt teaches the structure but takes longer to get to the answer.

For trainee electricians who haven't sat for the journeyman test yet, Holt is the better starting point. For licensed guys who already know NEC 230 from NEC 250 and just need to verify a working clearance under NEC 110.26, the Handbook or a fast reference app wins every time.

What Real Electricians Say

Talking with guys at supply houses and on job sites, the pattern is consistent. Mike Holt got them through the test. Most of them haven't opened the books in years. A few keep his grounding book around because NEC 250 still trips people up on inspections, especially the difference between separately derived systems and service-supplied systems.

The complaints are also consistent. Too long. Too much to wade through. Not searchable in a useful way. One master electrician put it like this:

I learned more from Mike Holt than any teacher I ever had. I also haven't watched a single video since I passed my master's in 2019. Different tools for different jobs.

Bottom Line

Mike Holt is excellent at what he set out to do. Train electricians to understand the code well enough to pass exams and work safely. If that's where you are in your career, buy his stuff. You will not regret it.

If you're already licensed and you just need to confirm receptacle spacing under NEC 210.52(A) or whether a panel needs a working space of three feet or more under NEC 110.26(A)(1), Holt is the wrong tool. Use a fast lookup, get your answer, and keep moving. Save the deep training for the truck after hours, when you're prepping for your next license upgrade.
