Mike Holt update frequency comparison (review 3)

Why update frequency matters more than feature lists

Code changes every three years. The NEC moves on a fixed cycle, and your reference material has to keep up or it becomes a liability. When you pull a permit under the 2023 NEC and your reference is still showing 2017 language, you are guessing. Guessing on bonding, GFCI placement, or working space clearances is how callbacks happen.

Mike Holt's products and Ask BONBON take very different approaches to keeping current. One sells you a new edition every cycle. The other updates in the background. Both have tradeoffs, and the right pick depends on how you actually work.

How Mike Holt handles code cycles

Mike Holt sells edition-locked products. The Understanding the NEC Volume 1 and Volume 2 books, the Illustrated Guide series, and the exam prep materials all ship tied to a specific code year. When the 2026 NEC drops, you buy the 2026 versions. The 2023 books stay on your shelf, accurate for 2023 jurisdictions, frozen otherwise.

The video library and online courses follow the same pattern. New cycle, new recordings, new purchase or renewal. The instruction is solid and the illustrations are some of the clearest in the industry. But the delivery model assumes you will refresh your library every three years.

• Books: republished per code cycle (2017, 2020, 2023, 2026)
• Videos: rerecorded per cycle, typically 6 to 12 months after NEC release
• Errata: posted to the website as PDFs, you have to check manually
• Continuing education: state-specific courses updated as states adopt

The lag problem nobody talks about

NFPA publishes the new NEC, then there is a gap before any third-party reference catches up. For Mike Holt, that gap is usually 6 to 12 months for books and longer for video content. During that window you are working off the old cycle while inspectors in early-adopting jurisdictions are already citing the new one.

Then there is the errata gap. NFPA issues Tentative Interim Amendments and errata throughout a cycle. Mike Holt posts corrections as PDFs on the site, but you have to know to look. If you bought the book in March and an erratum drops in November, your copy is wrong until you check.

Real tip: before any inspection on a job in a newly adopted code year, check the NFPA errata page and your reference's errata page. Five minutes saves a failed inspection.

How Ask BONBON updates

Ask BONBON pushes updates over the air. When the 2026 NEC is adopted in your state, the app reflects it without you buying anything new. Errata, TIAs, and clarifications get rolled in as they are published. You open the app, and what you see is current.

The model is different on purpose. Working electricians do not want to track which edition they own against which edition the AHJ enforces. The app handles that. Search NEC 210.8(A) and you get the language enforced in your jurisdiction, with the prior cycle available for comparison when you need it.

1. NFPA publishes change or erratum
2. Update is reviewed and pushed to the app
3. Your reference reflects it the next time you open it
4. No new purchase, no version tracking

Where Mike Holt still wins

Be honest about this. Mike Holt is the gold standard for code instruction. The illustrated explanations of grounding and bonding under Article 250, the breakdown of motor calculations in Article 430, the working through of services and feeders, that is teaching you how the code thinks. An app cannot replace sitting through a Mike Holt video on parallel conductors when you are studying for a master's exam.

If you are prepping for a license exam, doing a deep study of a specific article, or want a permanent reference for your truck or shop, the books earn their place. The depth is real and the production quality is high.

Picking the right tool for the work

The question is not which one is better. It is which one fits the moment. On the truck at 2pm trying to confirm whether NEC 210.52(C)(1) requires a receptacle on that 18 inch counter section, you want an app. Studying Article 250 on a Sunday morning to actually understand bonding jumpers and the grounded conductor, you want Mike Holt.

The update frequency difference matters most for daily field use. If your reference is six months behind your AHJ, you will eventually get burned. If your reference updates in the background while you focus on the work, that risk goes away.

Real tip: ask your inspector which code year they enforce and which errata they apply. Most will tell you straight. Then make sure whatever reference you carry matches.

Use both if you can. Mike Holt for learning, Ask BONBON for working. The tools solve different problems, and the update model is the clearest line between them.
