Mike Holt search comparison (review 2)

What I use, what I wanted, what I found

I've been pulling wire for 17 years. Most of that time, my code lookups happened on the tailgate with a dog-eared NEC handbook or a bookmarked Mike Holt forum thread. When I started testing Ask BONBON against Mike Holt's tools, I wasn't looking for a winner. I was looking for what actually saves me time when the inspector's standing behind me and the GC is asking when we're energizing.

This is a working electrician's read. Not a feature chart. I ran both through the same real jobs: a 200A service upgrade, a commercial kitchen with a mess of GFCI questions under 210.8(B), and a solar tie-in where 705.12(B) grammar matters.

Mike Holt: the library is the point

Mike Holt's strength is depth. The forum archives go back decades. If you want to read three electricians and a master argue about the neutral on a 3-phase 4-wire system, it's there. The illustrated graphics books and video training are the best in the trade, full stop. I learned service calcs from his material, and I still recommend the apprentice series to every first-year I run.

Search, though, is a different story. The site search is basically a forum search with a filter. You type "240.21(B)(1) tap rule" and you get a results page of threads, some 12 years old, some contradicting each other, with no way to tell which reply is from a CMP member and which is from a guy who got his license last month.

Tip: when you search Mike Holt, sort by date descending and look for replies from Mike himself or the named moderators. Everything else is crowd-sourced, which is useful but not authoritative.

Head to head: the GFCI question

Here was the test. Commercial kitchen, dishwasher receptacle inside a cabinet, 120V, 20A. Does it need GFCI under the 2023 NEC? The answer lives in 210.8(B) and the definition of a kitchen in Article 100. It's a question I get asked on job sites twice a month.

Mike Holt search: typed "dishwasher GFCI commercial kitchen." Got 40+ forum threads. First three were from 2017, 2019, and 2021, all predating the 2023 cycle change. Took me about 8 minutes to find a thread with the current language, and even then I had to cross-check against my code book because the thread was discussing a proposal, not the final adopted text.

Ask BONBON: typed the same query. Got the 210.8(B) citation, the 2023 revision callout, and a plain-English answer with the cabinet-mounted receptacle specifically addressed. Total time: about 20 seconds. I still opened the code book to verify, because that's the job, but I knew exactly where to look.

Where Mike Holt still wins

I'm not here to bury good work. Mike Holt beats everything when you need:

• Long-form explanation of why a rule exists. The historical context in his books is unmatched.
• Calculation walk-throughs. Service and feeder calcs per Article 220, motor calcs per 430, transformer sizing... his worked examples are how most of us learned.
• Exam prep. If you're sitting for a journeyman or master's test, his prep materials are the gold standard.
• Community. The forum, for all its search weaknesses, is where real problems get argued out by real electricians.

None of that goes away. I still buy his books. The point is that reading a 40-page chapter on grounding is a different task than figuring out whether a specific receptacle on a specific wall needs AFCI protection under 210.12.

Where search-first matters on the job

On a service truck, I have three or four minutes between a question from the apprentice and the next call. I don't need a forum debate. I need the article, the subsection, and the exception if there is one. The difference between a tool that answers in seconds and one that requires me to read five threads is the difference between billable work and standing around.

Mike Holt's material was built for study. Study time is real and valuable. But the job site is a different context, and a forum search doesn't fit it well.

Tip: if you're troubleshooting under pressure, ask the question the way you'd ask it out loud. "Can I land two neutrals under one lug on a 200A panel?" Natural-language search handles that. Keyword search on a forum often does not.

My actual recommendation

Use both. They solve different problems.

1. Keep Mike Holt for study, exam prep, deep-dive learning, and community. His books and videos belong on every electrician's shelf.
2. Use a fast search tool, whether Ask BONBON or something else, for in-the-field lookups where you need the right article in under a minute.
3. Always verify against the adopted code for your jurisdiction. 2023 NEC is not adopted everywhere yet, and amendments vary by state and city.

The honest take: Mike Holt built a library. Ask BONBON built a lookup. A library is where you learn the trade. A lookup is what you want in your pocket when the inspector asks why you ran 3/0 copper instead of 4/0 aluminum on that feeder. Different tools. Both earn their place on the truck.
