The Complete Handbook of Generators

Finally, a generator handbook written for people who actually use them. I manage equipment for three construction crews, and this book answers the exact questions I get asked constantly: why does a 5000-watt rating mean different things on different units, and which specifications actually matter for a job site. Chapter 1 alone—just the fundamentals on how a generator works and why efficiency matters—saved me from a bad purchase decision. This is the book I'm giving to every new site manager.

Good reference for the basics, and the load-calculation and sizing section in Chapter 3 is solid. But I expected more depth on the electrical side—grounding, bonding, transfer switches, utility interaction. For someone buying a single backup generator for home use, this is thorough. For an electrician or facilities manager dealing with standby systems on larger properties, it feels like it stops short. Still useful, just not quite complete enough for my work.

I appreciated the no-nonsense tone and the fact that every example is tied to real applications—construction sites, farms, data center backup. Chapter 1 actually explains what a generator does instead of assuming you know, and the troubleshooting chapter is practical and well-organized. My only wish is that there were more detail on fuel options and how propane versus diesel affects long-term storage and maintenance. Still, it's a solid handbook I refer to regularly.

Covers the fundamentals well and I liked the breakdown of different generator types. The chapter on choosing the right unit is helpful. That said, a lot of the content felt pretty surface-level for someone like me who's been in the HVAC contracting business for years. It's a decent primer for someone new to generators, but it doesn't push into the deeper technical territory experienced users might want. Good starter book, though.

I was looking for a book that would help me decide whether to start a generator rental business, and the business chapter is useful but pretty brief. The technical chapters are solid enough, but I wish there was more real-world data on pricing, margins, liability, and what actually keeps customers coming back. It's a good general reference, but it doesn't go deep enough into the business side to be a standalone guide.

The handbook does what it sets out to do—explain generators and how to choose one—but it reads like a reference manual, which I guess it is. Some sections are genuinely helpful (the maintenance and troubleshooting parts are straightforward and clear), but other chapters feel like they could have been condensed. I got what I needed from it for my farm backup system, but I didn't find it particularly engaging to read through from start to finish.

This is exactly what I needed. I'm a facilities manager for a mid-sized manufacturing plant, and we were upgrading our backup power system. Chapter 1 gave me the vocabulary and understanding to actually talk intelligently with our electrician and the equipment suppliers—I wasn't just nodding along. The specifications chapter showed me which numbers to focus on instead of being dazzled by marketing. Invaluable resource, and the Chapter 6 section on standby systems and parallel generators answered questions I didn't even know to ask yet. Highly recommend for anyone responsible for critical power.
