Mike Holt what they do better (review 8)

Who Mike Holt Is and Why It Matters

Mike Holt Enterprises has been teaching the NEC since 1975. Their textbooks, illustrated graphics, and video courses are in apprenticeship programs, JATC libraries, and CEU classrooms across the country. If you sat through code class, you probably opened one of his books.

Ask BONBON is a field tool. Mike Holt is a learning platform. Different jobs. But pretending they compete on the same ground would be dishonest, and electricians can smell that a mile off. Here is where Mike Holt genuinely beats us, and where the gap is real.

Illustrations That Actually Teach the Article

Mike Holt's graphics are the single biggest reason his material sticks. A color drawing of a service with grounded conductor, grounding electrode conductor, and bonding jumpers all labeled does more in 10 seconds than three paragraphs of 250.24 ever will. His team has been refining these illustrations for decades.

An app can define terms and cite articles. It cannot, today, replace a well drawn diagram of a 120/240V service showing exactly where the main bonding jumper lives. When an apprentice asks me what 250.28 is really saying, I still pull up a Holt illustration.

If you are studying for the journeyman exam, buy the Understanding the NEC Volume 1 workbook. Read it with the code book open on the bench. No app beats that workflow for learning.

Depth on Grounding and Bonding

Article 250 is where most electricians, including licensed ones, get tripped up. Mike Holt built his reputation on teaching it. His grounding and bonding course goes line by line through 250.4, 250.24, 250.30, 250.50, and the separately derived system rules in a way that very few instructors match.

That depth shows up in his written material too. When you hit a weird situation like a second building fed from the main, parallel feeders with individual equipment grounding conductors per 250.122(F), or a generator install under 250.35, his courses walk through the logic and not just the citation.

• 250.4 performance requirements, explained with circuit drawings
• 250.24(A)(5) restriction on the grounded conductor past the service
• 250.30 separately derived systems, step by step
• 250.66 vs 250.122 sizing, side by side

Exam Prep Is a Real Product

For journeyman and master exam prep, Mike Holt has a structured path. Practice questions, simulated exams, calculation workbooks for load calcs under Article 220, conduit fill under Chapter 9 Table 1, and voltage drop. Thousands of electricians have passed state and local exams using that material.

A reference app can help you look up an article fast when a proctor lets you bring the code book. It does not teach you how to do a 3 phase feeder calc under 220.61 with demand factors, and it does not drill you on the 50 questions you will see on a Florida or Texas master exam. Holt's exam prep does.

Video and Classroom Presence

Mike Holt himself, plus instructors like Ryan Jackson, are on camera explaining code changes every cycle. When the 2023 NEC dropped the expanded GFCI requirements in 210.8(A) and (F), or the emergency disconnect rule in 230.85, Holt had video walkthroughs out quickly with panel diagrams and install examples.

Video is a different learning channel than text. Some electricians learn better watching a guy point at a panel and explain why the neutral is not bonded on the load side. That is not a gap an app can close by adding more text.

Watch the free NEC code change summary videos Mike Holt posts every cycle on YouTube. Even if you buy nothing, you will catch the big changes before your AHJ cites you for them.

Where Ask BONBON Fits Differently

Here is the honest split. Mike Holt is the best tool on the market for learning the NEC, passing exams, and understanding why a rule exists. Ask BONBON is built for the moment you are already on the job, under a panel, and need to know if a specific install is compliant right now.

Field lookup speed, plain English answers to install questions, and working on a phone with gloves on is a different problem than classroom instruction. Both can live on your phone. They solve different halves of the trade.

• Studying for a test, learning a new article, understanding theory, go Mike Holt
• Standing on a ladder trying to remember if 210.52(C)(2) applies to an island under 9 square feet, go Ask BONBON
• Training an apprentice on grounding, Holt illustrations plus code book
• Settling an argument with the GC in 30 seconds, a fast reference app

What We Are Not Trying to Be

We are not a replacement for Mike Holt's training catalog. If an apprentice asked me how to prepare for their journeyman exam, I would send them to Holt first. If a journeyman asked me for the fastest way to check a receptacle spacing rule on a kitchen remodel, I would send them to a field reference tool.

Pick the tool that matches the moment. Most working electricians end up with both, and that is the right answer.
