Mike Holt side-by-side review (review 2)

Two tools, two different jobs

Mike Holt built an empire teaching the NEC. The books, the videos, the exam prep, all solid. If you are studying for a journeyman or master exam, his material is a proven path. Ask BONBON is not trying to replace any of that.

Ask BONBON is a code reference you pull out on the jobsite when the inspector is ten minutes away and you need to know if that 20A circuit in the garage needs GFCI, AFCI, or both. Different use case, different tool. This review compares them honestly from that angle.

Learning the code vs. looking it up

Mike Holt's strength is teaching. His illustrated guides walk you through 210, 250, 300, and 430 with diagrams, practice questions, and the reasoning behind each rule. You come out understanding why a grounding electrode conductor sizes off 250.66 and not 250.122. That depth matters for exams and for becoming a better electrician.

Ask BONBON is built for the moment you already know the concept but forgot the exact number. You type "receptacle height kitchen island" and get the answer with the NEC 210.52(C)(2) citation, not a 40 minute video. Both have a place. One teaches, one answers.

• Mike Holt: best for pre-exam study, classroom, and deep code understanding
• Ask BONBON: best for in-the-field lookups, inspections, and same-day code calls

Speed on the jobsite

A working electrician does not have time to scrub through a chapter of a PDF or queue up a Mike Holt video while standing on a ladder. The books are great at the truck or the shop. On the roof or in a crawlspace, they are not realistic.

Ask BONBON is designed for one-handed phone use. Ask a plain English question, get the cite. For example, "can I run NM cable exposed in a basement" returns the rule from NEC 334.15 with the specific conditions about running boards and guard strips. Mike Holt has that same info, but it is buried in chapter 3 material you have to navigate to.

If you are on a service call and the homeowner is watching, you need the answer in 20 seconds, not 20 minutes. Keep the Mike Holt book for Sunday morning. Keep a fast reference on your phone.

Accuracy and trust

Mike Holt's material is peer reviewed, hand edited, and has been the industry standard for decades. When his book says something about NEC 250.24(C), you can bet your license on it. That trust is earned over 40 plus years.

Ask BONBON is an AI tool that cites the NEC directly. It is fast and accurate for most lookups, but it is still a reference tool, not a replacement for the code book. Verify critical calls against the actual NEC text, especially on anything load calculation or grounding related. Same rule applies to any digital tool, Mike Holt's app included.

Cost and format

Mike Holt's 2023 NEC illustrated guides run around $80 to $200 per volume depending on the set. The full library with videos can push past $1,500. For an apprentice or a shop training multiple guys, that is a real investment but worth it for exam prep.

Ask BONBON is a subscription app. Cheaper month to month, but you are paying for access, not ownership. If you cancel, you lose the tool. With Mike Holt's books on your shelf, you own them for life. That tradeoff matters depending on how you work.

1. Buy a Mike Holt illustrated guide for the cycle you are working under
2. Use Ask BONBON for fast field lookups and odd questions
3. Keep a current NEC code book in the truck as the final authority

Where Mike Holt wins

Exam prep is not close. If you are sitting for a journeyman or master test, Mike Holt's practice questions and calculation workbooks are the gold standard. Ask BONBON can help you understand a rule in the moment, but it will not drill you through 500 practice problems with the methodology.

Teaching apprentices is another Mike Holt win. The illustrations, the consistency of the explanations, and the video library give a new electrician a structured path. Ask BONBON is a lookup tool, not a curriculum.

Where Ask BONBON wins

Plain English questions beat index lookups every time on a jobsite. Try finding the rule for EV charger load calculations in a book when your hands are dirty and you have a customer asking questions. NEC 625.42 and 220.57 are not where most people would start digging. Ask BONBON goes straight there.

Updates are another edge. When your local AHJ moves to the 2023 or 2026 NEC cycle, Ask BONBON updates. Your 2020 Mike Holt guide does not, which means a new set of books every cycle if you want current info.

Use both. Mike Holt on the bookshelf for learning and exam prep. Ask BONBON on your phone for the 50 times a week you need a citation in 20 seconds. They are not competitors, they are complements.

Bottom line

Mike Holt is the best in the business for teaching the NEC. That is not a competition Ask BONBON is trying to enter. If you are studying for an exam or training apprentices, buy his books.

For the working electrician who already knows the code but needs fast, accurate citations in the field, Ask BONBON is built for that job. Different tools, different problems solved. A smart electrician uses both.
