Choosing between two Cengage MindTap Course List wiring books comes down to building type: do you want a residential wiring guide or a commercial one? The 21st edition of Electrical Wiring Residential is built around residential electrical wiring, while Electrical Wiring Commercial by Ray Mullin and Phil Simmons is built around commercial electrical wiring. Both are English-language trade paperbacks in the same MindTap Course List series. The listed prices are close: $85.00 for the residential volume and $81.99 for the commercial volume, a $3.01 spread.
Quick verdict
The residential title is the clear pick when you want a book with an explicit edition label and an Adult & Further Education focus on homes. The commercial title is the pick when you are concentrating on commercial wiring and want the lower-priced side of the pair.
Comparison at a glance
| Focus | Listed price | Price bar |
|---|---|---|
| Electrical Wiring Residential (MindTap Course List), 21st Edition | $85.00 | |
| Electrical Wiring Commercial by Ray Mullin and Phil Simmons | $81.99 |
The two books share the MindTap Course List series, a trade-paperback format, and English-language text. Phil Simmons appears as the author of the residential volume and as co-author, with Ray Mullin, of the commercial volume. The price gap is small enough that focus, not cost, will usually be the deciding factor.
Where Electrical Wiring Residential wins
- It carries an explicit edition label, so you know this is the 21st edition.
- The Adult & Further Education designation points to post-school technical learners.
- Its topic is residential wiring, the right match for work in houses.
It is also the higher-priced side of the pair.
Where Electrical Wiring Commercial wins
- Its subject is commercial wiring, a different building context.
- It is the lower-priced side of the pair.
- It is a 640-page book with ISBN 9780357137697.
Electrical Wiring Residential (MindTap Course List), 21st Edition

This revised volume by Phil Simmons carries the Adult & Further Education designation in this pairing, and the title states the edition outright. Cengage Learning publishes it in English, and it is listed as Brand New. It is easy to name in a syllabus or study plan. Its price is the higher side of the pairing, so you are paying a little more for a residential-focused text with a clear edition label. Because the book is about residential wiring, it is the volume to reach for when your context is homes rather than commercial buildings.
Electrical Wiring Commercial by Ray Mullin and Phil Simmons

This revised volume from Cengage Learning is co-authored by Ray Mullin and Phil Simmons and is the lower-priced side of the spread. It is a 640-page book with ISBN 9780357137697. The commercial-wiring focus puts it in a different building context from the residential title. That focus is the trade-off: if your project is single-family residential, the other book's residential emphasis is more directly aligned. For a commercial-trades reader, it is a single-volume path into the same MindTap wiring family.
Final choice by use case
- Residential wiring context: choose the residential volume for its clear edition label and home-wiring focus.
- Commercial wiring context: choose the commercial volume for its commercial-wiring focus and lower-priced side of the pair.
- When the price gap matters: the commercial title is the money-focused choice because it sits on the lower-priced side.
