Student's and Professional's Guide to Power Generation and Delivery:
What it is...
Our new guide introduces the concepts of power generation and distribution. The material is broken down into short segments which concentrate on specific concepts or applications of particular types of equipment. The detailed explanations are written in easy-to-understand language and concisely presents the needed knowledge. There are many illustrations and photographs which help to provide technical understanding and provide real-world reference. This type of explanation and application better prepares the learner to perform effectively on the job in installation, troubleshooting, repair, and service of electrical power generation and delivery.
The knowledge obtained in this guide permits the learner to progress further in the study of electrical systems. It should be understood that the study of electricity and the application of electrical products are continually changing. The electrical industry constantly introduces new and improved devices and material which in turn lead to changes in installation and operation of equipment. Electrical codes also change to reflect the industry needs. It is it essential that the learner continues to learn and update their knowledge of the current procedures and practices.
The text is easy to read and the units have been grouped by general subject. There are summaries of each unit which provide an opportunity to restate the most important topics of the unit. There are summaries of the units provided to summarize topic groups.
Each unit begins with the learning objectives. An Achievement-Review Quiz at the end of each unit provides an opportunity for the learner to check their understanding of the material in small increments before proceeding. Some of problems presented in the guide require the use of simple algebra and the learner should be familiar with the math before trying to solve the equations . It is also essential that the reader have a basic understanding of the fundamentals of electrical circuits and basic electrical concepts.
It is recommended that the most recent edition of the National Electrical Code (published by the National Fire Protection Association) be available for reference and use as the learner uses this guide. Application state and local codes and regulations should also be consulted when making the actual installations.

Electromechanic Motor Starter; Electronic Motor Starters with Integrated Soft Starter Function
Motor Starter: This Siemens isolator module with its switch disconnector function serves to safely isolate the 400 V operating voltage when repair work is being carried out in the plant. It features an integrated group-fusing function, i.e. additional group short-circuit protection for all series-connected motor starters. Depending on their power distribution concept, all stations can be optionally fitted with an isolator module.

National Electrical Code 2005 Softcover Version
The single most important reference in the electrical industry, the National Electrical Code (NEC), is updated every three years and outlines minimum standards for all types of electrical installations. The 2005 NEC, available in softcover or looseleaf version, is loaded with solutions designed to provide better safeguards, add greater usability, and bring provisions in line with technology trends. A must for anyone involved in electrical design, installation, or inspection, the 2005 NEC® provides 100% of the information needed to meet Code® and avoid costly errors in electrical installations of all types. Thomson Delmar Learning is pleased to make this authoritative reference from the NFPA available directly from us, for the convenience of our customers who work in and around the electrical trades. It may be used independently or as a companion to any electrical book, including Delmar's best-selling wiring series as well as our guides to using the NEC®.
Every three years the National Electrical Cod2 is significantly revised to keep pace with technology and enhance protection against electrical fire and shock hazards. Get in position to advance your knowledge and be prepared with the newest codes. The 2005 National Electrical Code is loaded with solutions designed to provide better safeguards, add greater usability, and bring provisions in-line with technology trends. It's a "must" for anyone who works with electric conductors or equipment. Revisions include: Expanded AFCI protection in wiring systems New rules for GFCI protection Identification of ungrounded branch circuit and feeder conductors All-new articles for control panels and speed-drive systems Reorganized rules in Article 220: Branch Circuit, Feeder and Service Calculations New zone hazardous area classification system for combustible dusts and ignitable fibers and flyings. You'll help improve electrical safety for millions of people with the latest edition of the NEC; the world's most widely adopted safety code.
Required reference for handymen and professional electricians: "The National Electric Code, also knows as NFPA-70, is the standard that building officials use to define what is legal to use in electric services of all kinds. NFPA is the National Fire Protection Association. The Electric Code began almost as soon as Edison wired some of his new lights in New York, and the first electricity caused fire happened. Soon thereafter the National Fire Protection Association began writing safety codes aimed at preventing fires and promoting safe wiring techniques. Today, more than a century later, the Electric Code is republished every 3 years. As new inventions and new applications for electricity are ever expanding the code book expands and is revised to define the new applications. The 2005 edition has been updated to include recent developments in available materials and equipment. The code has 772 large pages detailing every electric installation from common house wiring to installation requirements for 35,000 volt transformers. The tables detailing how many conductors you can put in a conduit go on for 50 pages in the appendix.
The problem most people have with the code comes from its complexity and scope. If you are a handyman, or even an electrician, it takes years of study to learn all its requirements, and even then they change it on you. It can be helpful though. One year I was installing wire for a welder in my garage. I found a paragraph that allowed me to derate the current load of the conductors based on the duty cycle percentage of the welder. I saved quite a bit of money on heavy wire that wasn't needed, and had a safe installation. The code is so long and complex that several other books have been written to help professional and amateur electricians understand the code, translating it's stilted language and detailed requirements into plain English for common applications. The "Illustrated Guide to the National Electric Code," by Charles R. Miller, is one of the better ones. There are also numerous how-to handbooks on electric wiring based on the code. E.g., "Wiring Simplified," by Richter and others. is an easy do-it-yourself guide. However, even an illustrated guide book isn't the code. When the electric inspector comes out to review your work you need to know that you wired it correctly. You can bet he's read the code and will be approving or disapproving your work based on its requirements.
Over the years I've had to repair and straighten out many half-baked and outright dangerous electric installations. Many of them were done by well meaning men who just didn't know how electric wiring was supposed to be done. I recommend that everyone doing wiring from homeowner to seasoned electrician, to electric engineer ought to own a current copy of the National Electric Code. The 2005 edition will be current until 2008."
