The Late H. P. Richter wrote the first edition of Wiring Simplified in 1932. It was one of the first how-to books on wiring for general readers. It was followed by Practical Electrical Wiring in 1939. With the publication of each succeeding edition of these books, the author came to be regarded more and more widely as both the do-it-yourselfer's electrician and the electrician's electrician. He had the rare ability to write for both the amateur and the professional, and his books continue today in updated versions. W. Creighton Schwan, registered professional engineer and electrical consultant, is a recognized authority on wiring standards and practices. He has been the coauthor of Wiring Simplified and Practical Electrical Wiring and regularly contributes a column, "Code Comments," to the magazine Electrical Contractor. His background includes positions as supervising electrical inspector in Alameda County, California; electrical safety engineer for the California Division of Industrial Safety; and senior field engineer for nine western states for the National Electrical Manufacturers Association. He holds memberships in several professional organizations and has been an instructor at seminars on the National Electrical Code. Frederic P. Hartwell is nationally known for his expertise on National Electrical CodeR topics. He recently completed a major update of Practical Electrical Wiring and for nearly ten years was the senior editor and NEC expert with Electrical Construction and Maintenance Magazine. He is the author of numerous books on Code topics, including Illustrated Changes in the 1999 National Electrical CodeR. He has vast experience as an NEC and state electrical code panel member and trainer in NEC theory and applications, and brings years of experience and practical hints gained as a licensed master electrician, electrical inspector, and former head electrician at a Massachusetts college. He has been responsible for nearly one thousand successful proposals and public comments regarding changes in the Code beginning with the 1987 edition. He continues as a principal member of the NEC Committee, serving on Code Making Panel 9, and is secretary of the Massachusetts Electrical Code Advisory Committee.Richter, H. P. is the author of 'Wiring Simplified Based On The 2005 National Electrical Code', published 2005 under ISBN 9780971977907 and ISBN 0971977909.
