When you work in the HVAC electrical trades, the right reference book can be the difference between re-reading a code rule and actually understanding how it applies on a job. The four books in this lineup split into two groups: three take on the National Electrical Code with an illustrated, example-driven approach, and one walks through residential wiring methods from the service entrance to branch circuits. Your call comes down to how much condition matters and whether you want a code companion or a wiring-methods text.
Quick take
The three Illustrated Guide copies put the National Electrical Code first, while Electrical Wiring Residential takes a whole-house wiring approach. If you want a National Electrical Code companion, the 2021 Illustrated Guide To The NEC is the lowest-priced copy in that group. If you want a residential methods book, the Electrical Wiring Residential title is the one to choose.

Product notes
Illustrated Guide to the National - Paperback (Miller)
At USD 80.00, this Very Good trade paperback gives you the same Illustrated Guide title as the higher-priced Very Good copy but with a lower listed price. It comes from the MindTap Course List series and is described as an illustrated textbook, so it is a strong choice if you want code explanations with visual support. If you are choosing between the two Very Good copies, this one makes sense when price matters more than the exact page-condition detail called out on the higher-priced copy. Its limitation is that it focuses on the National Electrical Code rather than residential installation methods; the Electrical Wiring Residential title is the one that covers whole-house wiring.
Mindtap Course List Ser.: Illustrated Guide to the National Electrical Code
At USD 89.00, the listing is the most reassuring in this group when condition matters. The cover has light wear and creasing, but the pages are described as clean and like new, and the practice questions have not been filled in. That makes it the sensible choice if you plan to write in the margins as you work through the material. It costs more than the other Very Good copy and more than the 2021 edition, so you are paying for a cleaner study copy rather than a different book. The limitation is that it is the highest listed price in the line-up; if you are comfortable with a Good condition copy, you can spend less and still get the same general subject coverage.
Illustrated Guide To The NEC (Miller, 2021)
At USD 64.99, this 2021 paperback is the lowest-priced of the three Illustrated Guide copies in this comparison. It is described as a revised edition based on the 2020 NEC and includes full-color illustrations and wiring diagrams, which makes it a practical field reference for electricians, instructors, and students. The condition is Good, so expect a serviceable softcover rather than a pristine copy. Choose it when you want the 2020 NEC focus and are willing to save the difference compared with the Very Good copies. The limitation is the condition; if clean, unmarked pages are a priority, the two Very Good copies are the safer route.
Electrical Wiring Residential (Simmons & Mullin)
The lowest listed price in this group belongs to Electrical Wiring Residential at USD 63.09, but the condition is Acceptable. The listing describes it as readable but possibly beaten up, so it is a working reference rather than a shelf copy. What makes it worth considering is the approach: it covers residential wiring layouts and includes foldout plans, which sets it apart from the code-guide titles in this group. If your goal is to understand how a dwelling's circuits, panels, and branch wiring fit together, this is the book to get. Its limitation is simply the Acceptable condition; if you need a neat study copy, choose one of the Very Good titles instead.
Final recommendation by use case
For an NEC study companion on a tighter budget, the Illustrated Guide To The NEC (Miller, 2021) gives you the most useful combination of subject coverage and a listed price below the other two code guides. If you are willing to spend more for a copy with a stronger condition story, the Mindtap Course List Ser. title is the one to choose. For residential wiring methods, the Electrical Wiring Residential title is the only residential wiring option here, and its Acceptable condition is the main trade-off. If you want the lower-priced of the two Very Good copies of the Illustrated Guide, that is the natural pick.
