Unfortunately, Mike Holt himself doesn't offer a specific, published "highlighting guide" or list of what to highlight in the NEC (National Electrical Code) book. This is primarily because: Highlighting is Personal

What's important for one person (based on their job role, experience level, and type of work they do) might not be as critical for another. Highlighting should be tailored to your individual needs.

Dynamic Code

The NEC is updated every three years. A highlighting guide would quickly become outdated.

Holt's Teaching Style

He emphasizes understanding the concepts and how to find the information, rather than rote memorization or following a rigid set of highlights.

However, you can glean a lot from Mike Holt's videos and resources


Watch and Emulate

The best approach is to carefully watch his videos. Pay close attention to:

What articles he references frequently

These are clearly important.

Key words and phrases he emphasizes

These are often the terms he highlights. Look for words like "shall," "shall not," "permitted," "required," "approved," "listed," "labeled," and quantities/numbers (voltage, current, distances, etc.).

Definitions

He frequently points out the importance of understanding definitions (Article 100).

Tables

He often uses tables. Note the sections of tables he uses and consider highlighting those for quick reference.

Exceptions

Always note and highlight exceptions.

Warnings and Cautions

Highlight any warnings or cautions.2.

Consider the Type of Work You Do

If you primarily do residential work, focus on articles related to dwellings (e.g., Article 210 - Branch Circuits, Article 220 - Feeder Load Calculations, Article 230 - Services, Article 250 - Grounding). For commercial or industrial work, pay close attention to articles covering those types of installations (e.g., Article 500-516 - Hazardous Locations, Article 600 - Electric Signs and Outline Lighting, Article 620 - Elevators, Dumbwaiters, Escalators, Moving Walks, Platform Lifts and Stairway Chairlifts). If you're an inspector, focus on common violations and areas where confusion often arises.3.

Start Small and Iterate

Don't try to highlight everything at once. As you study and use the code, you'll naturally identify the sections that are most important to you. You can then go back and highlight those.4.

Use a Consistent Highlighting System



Color-coding

Use different colors for different categories (e.g., yellow for general requirements, green for grounding, blue for calculations, orange for warnings). Mike Holt often uses this.

Underlining vs. Highlighting

Consider underlining key words or phrases within a highlighted section.*

Marginal Notes

Write brief notes in the margins to remind yourself of the key points of a section. This is very helpful.5.

Take Practice Exams

Identify the articles you need to reference most often to answer practice questions, and use those articles to guide what you highlight.6.

Mike Holt's Products

Mike Holt offers courses, study guides, and exam preparation materials. These are not direct highlighting guides, but they implicitly point to the most important sections of the NEC by focusing on those concepts in the material. These are often good indicators of sections you should focus on.

In summary, while there isn't a ready-made list, carefully observing Mike Holt's videos, understanding your specific needs, and using a consistent highlighting system are the best ways to create a code book that works for you. Remember that the goal is to make the code book a useful tool for finding information quickly and efficiently, not just to decorate it with highlighters. Flag for review
