Mike Holt code update support (review 5)

What Mike Holt Actually Sells

Mike Holt Enterprises has been doing code education since the 80s. The catalog is deep: textbooks, DVDs, online courses, exam prep for journeyman and master, continuing education for license renewal, and code change updates every cycle. If you have ever sat through a CEU class, odds are the instructor used Holt material or learned from someone who did.

The flagship code update product is the Understanding the NEC Changes book, plus the matching video library. When the 2023 cycle dropped, Holt had the change book, the workbook, and the streaming videos out before most states had even adopted. The 2026 cycle is shaping up the same way.

This is not an app. It is a curriculum. That distinction matters when you compare it to anything you carry in your pocket.

The Code Update Workflow Holt Is Built For

Holt's update product assumes you sit down for a few hours, watch the video, mark up the book, and walk away understanding why 110.26 working space changed or why 210.8 keeps eating more receptacles every cycle. It is structured like a class because it is a class.

For continuing education hours, this is the right tool. Most states require 4 to 16 hours of code update CE for renewal, and Holt's courses are pre-approved in a long list of jurisdictions. You get the certificate, you keep your license, you actually learn something.

Tip: if your state requires NEC update CE, check Holt's approval list before you pay anyone else. The price per hour is competitive and the material is dense enough that it will stick.

Where It Stops Being Useful

You are on a service call. The homeowner added a kitchen island, the inspector flagged the receptacle layout, and you need to know right now whether NEC 210.52(C)(2) requires a receptacle on that island under the cycle your AHJ enforces. Holt's book is in the truck, in a milk crate, under a roll of MC. The video is on a laptop at the shop.

This is not a knock on Holt. It is a knock on the format. A 400 page change book is a study tool, not a lookup tool. The index is good, the cross references are good, but you still have to flip pages with one hand while holding a flashlight with the other.

Same problem with the videos. Great for learning. Useless when you need an answer in 30 seconds before the GC walks back over.

Honest Comparison: Holt vs Ask BONBON

These are not the same product and they are not trying to be. Here is how they actually fit together:

• Holt: learn the code, earn CE hours, build deep understanding of why a rule exists and how it changed.
• Ask BONBON: answer a specific question fast in the field, with the cited article, on the cycle your jurisdiction adopts.
• Holt: 2023 changes covered comprehensively in book and video form, 2026 update product on the way.
• Ask BONBON: 2017, 2020, 2023, and 2026 lookups in the same app, switchable per job.
• Holt: CE certificate at the end. State approved.
• Ask BONBON: no CE credit. Not a class. A reference.

If you only buy one, it depends on what you need. If your license is up for renewal and you need hours, Holt. If you are losing 20 minutes a day flipping through the codebook on rough ins, the app pays for itself before lunch.

What Holt Does Better

Three things, plainly:

1. Depth on the why. Holt explains the panel discussion, the substantiation, and the field problem that drove a code change. No app does this well, including ours.
2. Calculations practice. Box fill, conduit fill, voltage drop, motor sizing... Holt's workbooks force you to do problems until they are automatic. Critical for exam prep.
3. Instructor credibility. When Mike Holt or one of his senior instructors walks through a 250 grounding scenario, you trust it. That trust is earned over decades.

If you are studying for the master's exam or you have a new apprentice you want to train right, the Holt library is hard to beat.

What Holt Cannot Do

Code update support, the way Holt sells it, is retrospective. You learn what changed after the cycle is published, you take the class, you move on. It does not help you on Tuesday morning when an inspector cites a 2023 rule and you trained on 2020.

It also does not help when your AHJ is still on an older cycle. Plenty of jurisdictions are running 2017 or 2020 in 2026. A change book for the latest cycle does not solve the daily problem of working under whatever your inspector is actually enforcing.

Tip: before you start a job in a new town, call the building department and ask which NEC cycle they have adopted. Adoption lags publication by 1 to 4 years in most states. Use the cycle they enforce, not the one on the cover of your codebook.

Holt teaches the code. A good field reference helps you apply it. Different jobs, different tools, both worth owning.
