Origin of the National Electrical Code
  • First meeting held on March 18-19, 1896 in New
    York City
  • 23 persons in attendance
  • American Society of Electrical Engineers
  • American Institute of Architects

Origin of the National Electrical Code-Perspective
  • Edison had introduced the incandescent lamp 17
    years earlier
  • Alexander Graham Bell had invented his telephone
    only 20 years earlier
  • Wright Brothers would fly 7 years later.
  • Henry Ford worked for Detroit Edison

5
Electrical Codes in Use
  • There were 5 electrical codes in use in the USA
    in 1896
  • Manufacturers were unable to standardize products
    where there could be 5 variations of the product.

6
Development Approach
  • Take the best requirements from
  • The five electrical codes
  • The Electrical Code of Germany
  • The Rules of the British Board of Trade
  • The Phoenix Rules
  • The rules had to be safe as well as practical
  • The document was developed and circulated around
    the USA and Europe to 1200 experts

7
The First Edition
  • Issued in 1897 by the National Conference on
    Standard Electrical Rules

8
National Fire Protection Association
  • Assumed sponsorship in 1910
  • Published annual and biennial editions until 1959
  • Has published triennial editions since 1959
  • Published 41 of the 49 editions

9
Guiding Principles

    all of the answers.
  • Broad consensus of all affected industry segments
    necessary

    requires an installation code to be built around
    it.
