The practical reference for choosing, installing, and maintaining power and electrical supplies. No marketing, no fluff—just what professionals actually need to know.
About this book
Power and electrical supplies are infrastructure. They don't advertise themselves—they work or they fail. This handbook is written for the professionals, businesses, and serious hobbyists who need to specify them correctly, install them safely, maintain them reliably, and understand the business around them.
We skip the marketing and focus on what actually matters: How do you read a specification sheet and know what's real? Why does capacity matter more than peak rating? What makes a power supply fail, and how do you prevent it? When do you need redundancy, and when is it overkill? Whether you're an electrical contractor, facilities manager, data center operator, installer, or hobbyist building critical systems, you'll find concrete guidance on selection, installation, troubleshooting, and the real opportunities in this market.
This is a reference you'll return to—not because it's easy reading, but because it actually answers the questions that come up in the field.
Reader Reviews

★★★★★Finally, a handbook that doesn't treat me like I'm either a beginner or an electrical engineer. The chapter on choosing the right supply actually walks you through the logic of assessing your real load requirements versus what vendors claim—saved me from specifying the wrong UPS for our server room. My only wish is the troubleshooting chapter had a few more fault scenarios, but overall this is exactly what I reach for now instead of hunting through five different manufacturer spec sheets.

★★★★★This is the reference I've been waiting for. The first chapter alone—understanding what power supplies actually are and why undersizing or misconfiguring them costs you real money—is worth the price. It's written for people who actually install and maintain this stuff, not marketing departments. Clear, concrete, no fluff. Grabbed a second copy for my team.

★★★★★Been in electrical work for fifteen years and I don't usually read handbooks, but this one is different. It starts from real problems—load assessment, safety margins, code compliance—and shows you how to think through decisions instead of just following rules. The business opportunities chapter opened my eyes to consulting work I hadn't considered. Highly recommend for anyone who makes or specifies electrical equipment decisions.
