NFPA 70
National Electrical Code
2008 Edition
his edition of NFPA 70, National Electrical Code, was prepared by the National Electrical Codeommittee and acted on by NFPA at its June Association Technical Meeting held June 37, 2007, inoston, MA. It was issued by the Standards Council on July 26, 2007, with an effective date of August5, 2007, and supersedes all previous editions.
This edition of NFPA 70 was approved as an American National Standard on August 15, 2007.
History and Development of the National Electrical Code
The National Fire Protection Association has acted as sponsor of the National Electrical Code since911. The original Code document was developed in 1897 as a result of the united efforts of variousnsurance, electrical, architectural, and allied interests.
In accordance with the provisions of the NFPA Regulations Governing Committee Projects, aational Electrical Code Committee Report on Proposals containing proposed amendments to the 2005ational Electrical Code was published by NFPA in July 2006. This report recorded the actions of thearious Code-Making Panels and the Correlating Committee of the National Electrical Code Committeen each proposal that had been made to revise the 2005 Code. The report was circulated to all membersf the National Electrical Code Committee and was made available to other interested NFPA membersnd to the public for review and comment. Following the close of the public comment period, theode-Making Panels met, acted on each comment, and reported their action to the Correlating Com-ittee. NFPA published the National Electrical Code Committee Report on Comments in March 2007,hich recorded the actions of the Code-Making Panels and the Correlating Committee on each public
omment to the National Electrical Code Committee Report on Proposals. The National Electrical Codeommittee Report on Proposals and the National Electrical Code Committee Report on Comments wereresented to the 2007 June Association Technical Meeting for adoption.
NFPA has an Electrical Section that provides particular opportunity for NFPA members interested inlectrical safety to become better informed and to contribute to the development of the Nationallectrical Code and other NFPA electrical standards. At the Electrical Section Codes and Standardseview Session held at the 2007 NFPA World Safety Conference and Exposition, Section members hadpportunity to discuss and review the report of the National Electrical Code Committee prior to thedoption of this edition of the Code by the Association at its 2007 June Technical Session.
This 51st edition supersedes all other previous editions, supplements, and printings dated 1897,899, 1901, 1903, 1904, 1905, 1907, 1909, 1911, 1913, 1915, 1918, 1920, 1923, 1925, 1926, 1928,930, 1931, 1933, 1935, 1937, 1940, 1942, 1943, 1947, 1949, 1951, 1953, 1954, 1955, 1956, 1957,958, 1959, 1962, 1965, 1968, 1971, 1975, 1978, 1981, 1984, 1987, 1990, 1993, 1996, 1999, 2002, and005.
This Code is purely advisory as far as NFPA is concerned. It is made available for a wide variety ofoth public and private uses in the interest of life and property protection. These include both use in lawnd for regulatory purposes, and use in private self-regulation and standardization activities such asnsurance underwriting, building and facilities construction and management, and product testing andertification.
This 2008 edition includes the following usability features as aids to the user. Changes other thanditorial are highlighted with gray shading within sections and with vertical ruling for large blocks ofhanged or new text and for new tables and changed or new figures. Where one or more completearagraphs have been deleted, the deletion is indicated by a bullet () between the paragraphs thatemain. The index now has dictionary-style headers with helpful identifiers at the top of every indexage.n NATIONAL ELECTRICAL CODE 701tion
