This completely revised book clearly explains how to install rough and finish wiring in new construction, alterations, and additions. From basic electrical theory to advanced wiring methods to comply with the 2008 National Electrical Code. Here you'll find complete instructions on troubleshooting and repairs of existing wiring. Hundreds of drawings and photos show you how to plan and install wiring to code. Includes demand factors, circuit loads, and the formulas you need. Every subject is referenced to the 2008 National Electrical Code, and there are 21 pages of the most needed National Electrical Code tables to help your wiring pass inspection the first time.
Includes a CD-ROM with an interactive study center that helps you retain what you've learned, and study for the electrician's exam. Also on the CD is the entire book in PDF format with easy search features so you can quickly find answers to all your residential wiring questions.
It's one thing to install wiring that will carry power from the service entrance to outlets, switches and equipment throughout a home. But that's not enough. The wiring also has to give safe, trouble-free service and pass inspection. That means it has to comply with the latest National Electrical Code.
Here you'll find the basics of residential wiring - your complete guide to installing wiring the right way.
You'll learn about:
- Tools and gauges.
- Switch circuits.
- Service entrances.
- Rough and finish wiring.
- Wiring additions.
- Alterations to old work.
- Troubleshooting.
- Repairs.
The author explains what every electrician needs to know about electricity - how to select the right material, how to follow the plans, the types and spacing of outlets, and permissible loading on general purpose circuits.
This book is for anyone who wants to make a living wiring houses, but who is new to or rusty on current rules and theory for electrical work. Emphasis is on what the 2008 National Electrical Code allows, and how to avoid the errors new electricians often make. Includes over 20 pages of the 2008 National Electrical Code tables that you'll need and use the most.
Each chapter includes a set of multiple-choice questions based on that chapter. Test yourself to see if you need to back and review any of the material.
New in this edition: A CD-ROM with the Interactive Study Center - the Q & A in the book in fun-to-use interactive testing software. Click on your answer and choose either an instant response or a grade at the end of the entire test. More like playing a video game than studying, so you'll study more, do better on any state electrician's exam, and be better-equipped for the job.
Also on the CD: the compete book in PDF format. Use your computer's easy-search feature to take you directly to the information you need. You can even e-mail diagrams or installations instructions directly from the file to a worker on the job.
From the Introduction
This book was written for anyone who intends to make a living wiring residential buildings. If you can understand and follow the instructions in this manual, you should have no trouble installing safe, modern, efficient electrical systems in homes and apartments.
As an electrician, you need to know how to use a wide variety of tools and materials. This manual describes the tools that should be in every electrician's tool box, and suggests how they can be used to best advantage. I'll also explain what you should know about electrical materials: wire, cable, conduit, fixtures, boxes, switches, breakers and panels. There's a correct tool and a right material for every purpose. Sometimes selecting the right tools and materials isn't easy. After reading this book, you should have little trouble choosing both tools and materials appropriate for the work you do.
This manual isn't a book of electrical theory. But every professional electrician needs some background on how electricity is generated and distributed. And, of course, you should know how Ohm's Law and Watt's Law are used to design electrical systems. The first two chapters cover these important subjects.
If you've worked as an electrician for some time, you know that nearly everything an electrician does is governed by the National Electrical Code. For our purposes, the only right way is the code way. Until you're comfortable with the code, doing everything the code way can be a nuisance. Once you understand the code and the reasons for code requirements, you may have a different perspective. Most experienced electricians would agree that the National Electrical Code protects everyone (including electricians and electrical contractors) and is a good guide to professional practice - even if the building inspector didn't enforce it.
This book will help you follow the code. But it isn't a substitute for the National Electrical Code. Every professional electrician needs a copy of the current code. Many bookstores sell the National Electrical Code, or you can order a copy from this publisher, using the order form bound into the back of this book. But just having the current National Electrical Code isn't enough. Many cities and counties don't adopt the model code exactly as published by the National Fire Protection Association. Instead, they supplement the code with amendments or changes that will be enforced on jobs in that city or county. Once you have the current National Electrical Code, ask at your local building department about amendments or changes that apply in that jurisdiction. Keep those changes with your copy of the code.
I'll explain floor plans, cable plans and wiring diagrams in detail. This is important information for every electrician. The code has a lot to say about types of outlets, spacing of outlets, what must be switch-controlled and what need not be switch-controlled. The work you do will have to follow the plans and comply with the code. The information in this book should help you understand and follow plans prepared for your jobs.
Finally, I'll explain how to diagram the circuits you're likely to find in a home or apartment. As a teacher of electrical wiring for many years, I've found that a student who can diagram a circuit correctly has a reasonably good chance of wiring it correctly as well. And a student who can't diagram a circuit probably can't install it either!
Now let's get down to business - what you need to know to wire homes and apartments.

About the Author
Jeff Markell worked for over 30 years as a licensed general contractor in residential and commercial construction, and is author of several technical manuals.
As an instructor of electrical wiring to apprentice electricians, he looked for a practical manual that would supply the hands-on instructions they needed to install wiring that complies with the latest NEC. Finding none, he wrote this one.
