`
`National Electrical Code”
`
`2017 Edition
`
`This edition of NFPA 70, National Electrical Code, was prepared by the National Electrical Code
`Committee and acted on by NFPA atits Jane Association Technical Meeting held June 13-16, 2016,
`in Las Vegas, NV. It was issued by the Standards Council on August 4, 2016, with an effective date of
`August 24, 2016, and supersedes all previous editions.
`
`This document has been amended by one or more Tentative Interim Amendments (TIAs) and/or
`Errata. See “Codes & Standards” at www.nfpa.org for more information.
`
`This edition of NFPA 70 was approved as an American National Standard on August 24, 2016.
`
`History and Developmentof the Nafional Electrical Code ®
`
`The NationalFire Protection Association has acted as sponsorof the National Electrical Code since
`1911. The original Code documentwas developed in 1897 as a result of the united efforts of various
`insurance, electrical, architectural, and allied interests.
`
`In accordance with the Regulations Governing the Development of NFPA Standards, a National
`Electrical Code First Draft Report containing proposed amendments to the 2014 NationalElectrical
`Code was published by NFPA in July 2015. This report recorded the actions ofthe various Code-
`Making Panels and the Correlating Committce of the National Electrical Code Committee on each
`public input and first revision that had been madeto revise the 2014 Code. The report was published
`at www.nipa.org/70. Following the close of the public commentperiod, the Code-Making Panels
`met, acted on each comment, and created some second revisions, which were reported to the
`Correlating Committee, NFPA published the National Electrical Code Second Draft Report in April
`2016, which recorded the actions of the Code-Making Panels and the Correlating Committee on
`each public comment on the National Electrical Code Committee First Draft Report. The National
`Electrical Code First Draft Report and the National Electrical Code Second Draft Report were
`presented to the 2016 June Association Technical Meeting for adoption.
`
`NFPA has an Electrical Section that provides particular opportunity for NFPA members interested
`in electrical safety to become better informed and to contribute to the developmentofthe National
`Electrical Code and other NFPA electrical standards. At the Electrical Section Codes and Standards
`Review Session held at the 2016 NFPA Conference and Expo, Section members had the opportunity
`to discuss and review the report of the National Electrical Code Committee prior to the adoption of
`this edition of the Code by the Association at its 2016 June Technical Session,
`
`This 54th edition supersedes all other previous editions, supplements, and printings dated 1897,
`1899, 1901, 1903, 1904, 1905, 1907, 1969, 1911, 1913, 1915, 1918, 1920, 1923, 1925, 1926, 1928, 1930,
`1931, 1933, 1935, 1937, 1940, 1942, 1948, 1947, 1949, 1951, 1953, 1954, 1955, 1956, 1957, 1958, 1959,
`1962, 1965, 1968, 1971, 1975, 1978, 1981, 1984, 1987, 1990, 1993, 1996, 1999, 2002, 2005, 2008, 2011,
`and 2014,
`
`This Code is purely advisory as far as NFPA is concerned.It is made available for a wide variety of
`both public and private uses in the interest of life and property protection. These include both use in
`law and for regulatory purposes and use in private self-regulation and standardization activities such
`as insurance underwriting, building andfacilities construction and management, and product
`testing and certification.
