From the Preface
This book has been prepared with the objective of providing coverage of major changes in the 2011 National Electrical Code. Great care has been taken to select changes that provide the best, most complete information and greatest benefit to inspectors and installers alike. There were 5,016 proposals and 2,910 public comments processed by the twenty code - making panels. Obviously, this book does not include every proposal and public comment that was accepted nor does it include any that was rejected.
Significant effort has been made to include references to proposals and public comments as part of the coverage of each change covered in the Analysis of Changes. The objective is to make it easier to follow the progress of proposed changes and to better understand how the change developed and was finally accepted. Proposals and public comments were selected based on their industry impact on the final accepted change. Selections were made to provide the reader with sufficient information that shows action on the change from start to final acceptance. Readers are encouraged to review the substantiation included with proposals and comments associated with changes to get a more complete understanding of what the submitter intended to accomplish and why the action was proposed. It also helps to understand how the proposed change reaches final form by following actions and statements made by the NEC committees. Users of the 2011 National Electrical Code are encouraged to obtain either the electronic form or the printed hard copy of the NEC Report on Proposals and the NEC Report on Comments. These valuable resources include a more detailed record of each change and provide actual panel actions and statements to help clarify the changes that were accepted.
The NEC is continually being revised due to its inherent dynamics, and the focus in recent code cycles has been on making the document more user-friendly. Developing it into a set of safety rules involving a technically complex industry and having that document in a form where it can be adopted by a legislative body to become law is challenging. Coordinating and developing the material for the Analysis of Changes would not be possible in the short time frame involved in the NEC development process without the help of many people. The IAEI code panel representatives who participated by providing useful information that enabled this document to be developed are to be commended for their contribution to the overall work. Individual members of the IAEI staff who worked long hours and through many difficulties should also be recognized: Principal Developer, L. Keith Lofland, director of education, codes and standards, contributing developer, and technical reviewer; Jonathan Cadd, codes and standards coordinator; John Watson, creative director; Laura Hildreth, research editor; and Kathryn Ingley, managing editor. Their talents combined with their professional training and. experience enabled IAEI to develop and produce progressively superior training material that aids IAEI in achieving its objectives. It is also important to recognize industry contributions of product photos and text review. From all who helped make this document possible, it is hoped that readers will find it to be an important source of practical information regarding changes in the NEC and that it is presented in a manner that it is both enjoyable to use and easy to understand.
