The Complete Handbook of Surge Protection Devices

I've been rewiring buildings for 15 years and I'm embarrassed to admit how much I didn't know. This book finally explains why the Type 1 vs Type 2 distinction matters in a way I can explain to a client. The section on lead length and its effect on let-through voltage alone paid for the price. I've already specified correctly sized units on two jobs since I read it. The grounding chapter should be required reading for every apprentice.

I bought this because I manage a small data center and got tired of replacing server power supplies after storms. The troubleshooting chapter helped me realize my problem wasn't surge voltage but repeated sags that were wearing out the power supplies. The book's plan for installing a Type 2 unit at the panel and a Type 3 at each rack made sense. It's a dry read, but it's the first technical book on this subject that didn't feel like a sales pitch.

This is the reference I wish existed when I started my AV installation side business. The chapter on business opportunities is practical and grounded — not the usual 'hustle' nonsense. The comparison table for MOV vs GDT vs TVS behavior is worth the whole book. It's not flashy, but neither is good electrical work. The appendix that covers reading datasheets caught a few things I've been misreading for years. I've recommended it to two other installers already.

I'm a hobbyist with a workshop full of microcontrollers and old test equipment, and I wanted to stop guessing about surge protection. This handbook doesn't dumb things down, but it's also not impenetrable. I especially liked the concrete examples of actual surge events and how they damaged equipment. The explanation of how a joule rating is calculated was clarifying. My only minor complaint is the chapter on future trends felt thin compared to the rest. Still, I've already ordered a Type 3 protector for my benchtop setup.
