The National Electrical Code Procedure and Revisions

IEEE Transactions on Industry and General Applications, 1967

A brief history is given of the development of the present committee structure for producing and revising the National Electrical Code. The procedure permits anyone to submit proposed revision of the code and provides a method of processing which insures a consensus and thus recognition as an American standard. A review is made of the schedule of revision and the steps taken to insure opportunity for review by industry before adoption. Technical committees are used to solve special problems where additional knowledge is needed. The intended function of tentative interim amendments and official interpretations are explained. Changes made in the 1965 edition of the National Electrical Code includes detailed coverage of multi-speed and part-winding motors, definition of unattended expansion of group motor applications, and motor disconnecting means. Other changes pertain to working space, 300-volt fuses, corrosion protection, new types of wire insulation, conduit fill and main protection for lighting, and appliance branch circuit panelboards.

Safety Code ® C2-2007

This standard covers basic provisions for safeguarding of persons from hazards arising from the installation, operation, or maintenance of (1) conductors and equipment in electric supply stations, and (2) overhead and underground electric supply and communication lines. It also includes work rules for the construction, maintenance, and operation of electric supply and communication lines and equipment. The standard is applicable to the systems and equipment operated by utilities, or similar systems and equipment, of an industrial establishment or complex under the control of qualified persons. This standard consists of the introduction, definitions, grounding rules, list of referenced and bibliographic documents, and Parts 1, 2, 3, and 4 of the 2007 Edition of the National Electrical Safety Code. . The Discussion of the NESC, issued as NBS Handbook H4 (1928 Edition) for the 4th edition of the NESC and as NBS Handbook H39 for Part 2 of the Grounding Rules of the 5th edition, was not published for the 6th edition.
