Quick Take
For anyone working in the HVAC electrical trades, the first decision is about study style: do you want a portable, illustrated code guide or a complete exam-prep system? The three Illustrated Guide to the National Electrical Code paperbacks by Charles Miller are all under $100 and built around visual explanations. Mike Holt's Electrical Exam Prep Course, Master/Contractor Comprehensive, is a DVD/mixed-lot package aimed at a much bigger goal: passing a Master or Contractor license exam. The right choice depends on whether you need to look up code rules or sit for a high-stakes test.

- If you are preparing for a Master or Contractor license exam, the Mike Holt course is the only option here designed around the 2026 NEC and packaged as a DVD/mixed lot.
- If you need a specific course-series edition, two of the Miller paperbacks share that series, so compare the lower-priced copy first.
- If you are unsure how deep to go, start with the lowest-priced Miller guide and add more materials only after you know the exam format you face.
Product Notes
Illustrated Guide To The NEC Charles R Miller PB Blue Cengage 2021 USA
At the lowest price in this group, this Cengage trade paperback is an illustrated companion to the 2020 National Electrical Code. The format is portable, and the content is aimed at electricians, instructors, and students who want diagrams and code explanations in one place. If you're buying a reference to use alongside your current work, this is the least expensive place to start. The trade-offs are the Good condition and the 2020 code focus, so it is not the copy to choose if your study plan depends on the 2026 NEC.
Illustrated Guide to the National - Paperback, by Miller Charles-9780357766712
This Very Good paperback belongs to the MindTap Course List series and carries ISBN 9780357766712, which helps you match it to a course that uses that identifier. The book includes the illustrated approach used across the Miller guides, and the adult/further education level points to learners beyond the basics. The limitation is the format and price position: it's a printed guide rather than a multimedia course, and it costs more than the lowest-priced Miller edition. If you don't need the MindTap identification, the lowest-priced Miller edition is the more direct value.
Mindtap Course List Ser.: Illustrated Guide to the National Electrical Code
This edition shares ISBN 9780357766712 with the previous copy and is also Very Good. The MindTap Course List series name appears in the title, so it is easy to identify if you are collecting course materials from that series. The trade-off is price: it is the highest-priced of the three Miller guides, and it shares the same ISBN and format as the lower-priced copy. If the exact series name matters more than the extra cost, this is the one to pick.
Electrical Exam Prep Course, Master/Contractor Comprehensive, 2026 NEC Mike Holt
This is the comprehensive option. The Mike Holt course is Brand New and comes in a DVD / mixed lot format, and the title targets the 2026 NEC Master/Contractor exam. If you want a complete study system rather than a reference book, this is the course to pick. The limitation is the scale: it costs over $1,000, and the mixed-media format is not built for quick flipping. It's a deliberate purchase for someone preparing for a licensing exam.
Final Recommendation by Use Case
- For a portable, low-cost code reference: Choose the $64.99 Illustrated Guide To The NEC if you want an illustrated paperback and are comfortable with Good condition.
- For a course-series edition at a lower price: Choose the $80.00 Miller paperback if you want that edition in trade paperback form.
- For the same course-series when the series name matters: The $89.00 edition is the other copy with the series name in the title, so it works when you want that exact series name on the book.
- For a full Master/Contractor exam-prep system: Choose Mike Holt's $1,050.00 course if you want a DVD/mixed lot rather than a printed guide.
