Mike Holt reviews from electricians (review 8)

What electricians actually say about Mike Holt

Spend ten minutes in any apprentice break room or contractor forum and Mike Holt's name comes up. The reviews from working electricians tend to land in the same place: the content is solid, the man knows the code, and the production value beats most trade education. The complaints are also consistent, and they matter when you are pricing out a study path or trying to pass the exam next month.

This is an honest read from the field, not a sponsored take. If you are weighing Mike Holt against other study tools or against a code reference like Ask BONBON, here is what the reviews actually say once you cut through the marketing.

What electricians praise

The strongest reviews come from journeymen prepping for the master's exam and apprentices in the back half of their program. Holt's grounding and bonding material, in particular Article 250, gets called the gold standard. Electricians say his explanations of NEC 250.4(A) for grounded systems and 250.4(B) for ungrounded systems finally made the why click after years of just memorizing the how.

The other consistent praise: his treatment of NEC 310.15 ampacity adjustments, NEC 220 load calculations, and the GFCI/AFCI requirements under NEC 210.8 and 210.12. Reviewers say the illustrations and worked examples are what separate his books from a dry code commentary.

• Strong on grounding, bonding, and the 250 series
• Clear on motor calcs (NEC 430) and transformer sizing (NEC 450)
• Exam prep tracks with a high reported pass rate
• Free YouTube content is genuinely useful, not a teaser reel
• Updated for each code cycle, currently NEC 2023

What electricians complain about

The complaints cluster around price, format, and field usability. The full exam prep bundles run several hundred dollars, and the textbook plus video plus question bank combos push past a thousand. For an apprentice making first-year wages, that is real money. Reviewers who paid out of pocket are noticeably more critical than those whose locals or employers covered it.

The bigger complaint is format. Holt's material is built for studying, not for looking up an answer on a Tuesday afternoon when you are standing in a panel and the GC is asking why you cannot land that circuit. Flipping a 600 page workbook on a ladder is not a workflow. Several reviewers note they keep Holt at home for study and use something else on the truck.

• Price point is steep for self-funded apprentices
• Not designed for quick code lookups in the field
• Video courses can feel slow at 1x speed
• Some examples lag the latest code adoption in your state

Study tool, not a field reference

This is the distinction that comes up over and over in honest reviews. Mike Holt is excellent at teaching you the code. He is not trying to be the thing you pull out when you need to verify working clearance under NEC 110.26 with a customer waiting. The product is a curriculum, not a reference.

That matters because electricians often buy Holt expecting it to do both jobs and end up frustrated. The reviewers who are happiest are the ones who treat it as exam prep and continuing education, then pair it with a separate tool for jobsite lookups.

Field tip: keep your Holt textbook on the bookshelf at home and run through one chapter a week. Use a fast lookup tool on the truck. Mixing the two roles is how the book ends up covered in wire pulling lube.

Who Mike Holt is right for

Based on the pattern of reviews, the buyer who gets the most out of Holt is the electrician with a clear study goal and a few months of runway. Master's exam in 90 days, journeyman exam in 60, or a contractor wanting to actually understand grounding instead of guessing. If that is you, the price pencils out.

The buyer who regrets it is the electrician who wanted a code companion on the job and bought a curriculum by mistake. Reviewers in this group say the material is good but they are not going to sit down for two hour video sessions after a ten hour day in an attic.

1. Apprentices in years three and four prepping for the journeyman exam
2. Journeymen targeting the master's or contractor's license
3. Electricians who want to deeply understand NEC 250 grounding
4. Anyone teaching apprentices and looking for a structured curriculum

The honest comparison

If you already own a current NEC handbook and you need to pass an exam, Mike Holt is hard to beat for the curriculum side. Reviews back that up. If you are looking for the tool you reach for when you are roughing in a kitchen and need to confirm the receptacle spacing under NEC 210.52(C) or the GFCI rule under NEC 210.8(A), Holt is not built for that and the reviews say so.

Most working electricians end up with a stack: the code book itself, a study program like Holt for exams and CEUs, and a fast lookup app for the truck. The reviews stop being contradictory once you stop expecting one product to do all three jobs.

Field tip: before you spend $400 on a course, check whether your local, your employer, or your state CEU reimbursement will cover it. A surprising number of electricians pay full price for material their union hall already licensed.

The short version of the reviews: Mike Holt is a strong teacher, a fair-to-expensive product depending on who pays, and the wrong tool to bring up a ladder. Buy it for the exam. Use something else on the job.
