Mike Holt what Ask BONBON does better (review 7)

Two tools, two jobs

Mike Holt built an empire teaching the Code. His books, videos, and continuing ed courses are the gold standard for classroom learning. If you are prepping for a master's exam or want to understand why 250.122 sizes equipment grounding conductors the way it does, Mike Holt is where you go.

Ask BONBON does something different. It answers Code questions in the field, in seconds, while you are standing on a ladder with a meter in one hand. Different tool, different moment.

Here is the honest split, from an electrician who owns both.

Speed on the job

Mike Holt's materials are deep. That depth is a feature in a classroom and a bug at 2pm in an attic. Flipping through a 400 page illustrated guide to find the GFCI rule for a dwelling basement receptacle is not realistic when the inspector is due in twenty minutes.

Ask BONBON is built for that moment. Type "GFCI basement receptacle" and you get NEC 210.8(A)(5), the exception for dedicated appliance outlets, and the 2023 expansion to 250 volts. No scrolling, no index, no paywall in the middle of the answer.

Field tip: if you are pulling a permit under the 2023 NEC, confirm your AHJ has actually adopted it. Some jurisdictions are still on 2020 or even 2017.

Where Mike Holt wins

Credit where it is due. Mike Holt beats Ask BONBON, and most other tools, in a few areas:

• Exam prep. The practice questions, calculation workbooks, and video walkthroughs are unmatched for journeyman and master's exams.
• Code changes explained. The cycle-by-cycle change summaries (2017 to 2020, 2020 to 2023) are clear and thorough.
• Theory. If you want to actually understand grounding versus bonding, or why voltage drop matters beyond the 3 percent rule of thumb, his videos are worth the money.
• Continuing education. State-approved CEU credits with a trusted name behind them.

If you are studying, buy his stuff. Nothing Ask BONBON does replaces a structured curriculum.

Where Ask BONBON wins

Ask BONBON is not trying to teach you the Code. It assumes you already know it, mostly, and need a fast reference for the 5 percent you forget or the edge cases you hit once a year.

Concrete wins over Mike Holt's reference materials:

1. Plain English questions. Ask "can I share a neutral on a multiwire branch circuit feeding a kitchen" and you get 210.4(B) handle ties, 300.13(B) splicing rules, and the answer. You do not need to know the article number first.
2. Offline on the truck. Works in a basement, a mechanical room, or a job site with no signal. Most Mike Holt content is print or streaming video.
3. Always current. When the 2026 NEC drops, Ask BONBON updates. You do not buy a new book.
4. Calculations inline. Box fill, conduit fill, voltage drop, ampacity adjustment for 310.15(B) all return a number plus the citation, not a worksheet.
5. Cross references. Ask about a 50 amp range circuit and it pulls 210.19(A)(3), 220.55, Table 220.55, and the demand factor note without you chasing them separately.

Cost and access

Mike Holt's full library, books plus videos plus online courses, can run into the thousands over a career. The value is there if you use it, but it is a real line item. A single illustrated NEC guide is around 200 dollars and it is obsolete in three years.

Ask BONBON is a subscription app. You pay monthly, it updates automatically, and it lives in your pocket. It is cheaper than one Mike Holt code book per year and you use it every day instead of once a quarter.

Neither tool is free. Both earn their keep if you use them for the right thing.

How working electricians use both

The guys who get the most out of both tools use them in different gears:

• Mike Holt at night, on the couch, studying for the master's or brushing up on a cycle change.
• Ask BONBON on the job, when a GC asks if a receptacle needs GFCI or AFCI or both, and you need the answer before he walks away.
• Mike Holt when a rough inspection fails and you want to understand the ruling deeply enough to argue it.
• Ask BONBON when you want to avoid the failed rough in the first place, by checking 314.16(B) box fill before you close it up.

Field tip: save your Ask BONBON answers for recurring questions. Commercial kitchen hood circuits, pool bonding, EV charger load calcs... the same three or four come up on every job.

You do not have to pick. Mike Holt teaches you the Code. Ask BONBON hands you the Code when you need it. Use the right one for the moment and both become cheap.
