Mike Holt what they do better (review 7)

Mike Holt built the training empire for a reason

Mike Holt Enterprises has been teaching the NEC since 1975. That is 50 years of refining how electricians actually learn code. Ask BONBON is a reference tool for the truck, the attic, and the panel. Mike Holt is a training company that turns apprentices into journeymen and journeymen into masters. Different jobs, and he does his job extremely well.

This is an honest look at where Mike Holt beats everything else out there, including us. If you are studying for a license exam or trying to actually understand the code instead of just looking up answers, his stuff is the gold standard.

Illustrated explanations that actually click

The single biggest thing Mike Holt does better than anyone: illustrations. His Understanding the NEC Volume 1 and Volume 2 books walk through articles with full color diagrams showing exactly what the code is describing. Look at a grounding and bonding article cold and it reads like tax law. Look at the same article with a Mike Holt diagram next to it and you see what the conductors are doing.

Text alone cannot teach you why a bonding jumper belongs where NEC 250.102(C) says it belongs. A picture of current fault paths with the jumper in place and then removed shows you in five seconds. That is pedagogy, and nobody in the NEC space does it at his level.

If you are preparing for a journeyman or master exam and you have never cracked a Mike Holt Understanding book, you are studying on hard mode. Borrow one before you buy one, but get your hands on one.

Deep coverage of grounding, bonding, and services

Grounding and bonding is where most electricians get tripped up, and it is where Mike Holt goes deepest. He has entire dedicated books and video series just on Article 250. Same for services, feeders, and branch circuits under Articles 220, 230, and 240. When the code gets dense, his material gets more detailed, not less.

Topics where his training material is hard to beat:

• Grounding electrode systems, NEC 250.50 through 250.70
• Bonding of services, NEC 250.92
• Load calculations, NEC 220 Parts III, IV, and V
• Overcurrent protection and tap rules, NEC 240.21
• Transformer grounding and separately derived systems, NEC 250.30

A reference app can tell you what NEC 250.30(A)(1) says. A Mike Holt video can tell you why it says that and what happens on the actual install when you get it wrong.

Exam prep that gets people licensed

Nobody has a track record on license prep like Mike Holt. His state specific exam prep packages, practice questions, and simulated exams have put a lot of electricians through the journeyman and master tests. The questions are written in the same format the PSI and Prometric exams use, and the timing drills train you to flip pages fast.

If you are sitting for an exam in the next six months, his prep material is worth the money. The code book tabbing guides alone will save you minutes per question, which is the difference between passing and failing when the clock is tight.

A working electrician passing a master exam is not the one who memorized the most code. It is the one who can find the answer in the book fastest. Tabbing strategy matters more than you think.

Continuing education with substance

Most CEU courses are a joke. Click through slides, answer a gimme quiz, print the certificate. Mike Holt CEU courses actually teach the code changes between cycles. His 2023 code change material covered the new GFCI rules under 210.8, the updated surge protection requirements in 230.67, and the emergency disconnect rules in 230.85 in genuine depth.

When the 2026 NEC rolls out in your state, his change analysis will be out fast and it will be accurate. That matters for guys doing commercial work where a missed code change can mean a failed inspection on a six figure job.

Where the two approaches fit together

Mike Holt is for learning the code. Ask BONBON is for using the code on the job. Those are not the same task and they do not compete the way people sometimes assume.

Real workflow for a lot of electricians looks like this:

1. Study a topic deeply through Mike Holt books or videos during apprenticeship or exam prep
2. Build the mental model of why the code reads the way it does
3. Pass the license exam
4. Get on the truck and need to confirm a specific ampacity or clearance at 10am on a Tuesday
5. Pull up a reference app, get the answer in 15 seconds, keep working

You want both. The training builds the understanding. The reference tool keeps the day moving. Anyone telling you one replaces the other is selling you something. Mike Holt built a training empire because training is hard to do well, and he does it better than anyone in this trade.
