A no-nonsense, standards-based guide to selecting, using, and maintaining extension cords for work and serious projects.
About this book
This is the definitive practical reference on extension cords, written for people who use them to get work done. From a 100-foot feeder on a film set to a 25-foot shop cord for a table saw, this book cuts through the marketing fluff and focuses on the physics, the standards, and the real-world choices that keep your equipment running and your site safe. You will learn how to decode the NEC and UL markings on the jacket, understand the difference between AWG and amperage ratings, and know why your cord is getting hot before it becomes a fire hazard. This is not a buyer's guide for this season's models; it is a curriculum on how to think about temporary power distribution.
The handbook is structured to build your expertise step-by-step. It begins with the fundamentals of how a cord works, moves through a detailed breakdown of types and specifications, and then provides a decision-making framework for choosing the right cord for specific tasks and environments. Dedicated chapters cover correct installation and usage techniques to prevent tripping hazards and voltage drop, as well as a robust maintenance and troubleshooting section that will help you extend the life of your investment and diagnose problems like a professional. The book concludes with a practical look at the business side of extension cords, future material and regulatory trends, and a clear glossary of terms.
Whether you manage a warehouse, run a mobile repair service, or just demand more from your workshop, this handbook provides the concrete, standards-based knowledge you need. It is a resource you will consult repeatedly, from the initial purchase to the moment you decide whether a cord is worth repairing or should be retired for good.

★★★★★I've been a journeyman electrician for 15 years and bought this mostly out of curiosity, but I was genuinely impressed. The chapter on understanding what's actually happening inside the cord finally put a clear picture on why some cheap cords run hot and others don't. It's not a dry rehash of code; it's practical physics you can use. The safety chapter alone is worth the price of the book, especially the part about the 'last 5 feet' and GFCI. I've already recommended it to two of my apprentices. It's the reference I wish my company provided when I started out.
