Latest Version Of The National Electrical Safety Code Available Through IEEE

Source: IEEE

Piscataway, NJ - The National Electrical Safety Code® (NESC®) has been updated and the latest version, the 2007 National Electrical Safety Code, is now available through the IEEE, the primary resource for NESC information. The Code, which is used throughout the U.S. and in over 100 countries, offers practical guidance on safeguarding employees and the public when electrical supply and communication lines are designed, installed, operated and maintained. It is updated every five years to reflect changes in the electrical and communications industries.

In addition to the new version of the NESC, the IEEE also offers the "NESC Handbook, Sixth Edition", a companion to the Code that gives users insight into its rules and how to apply them. The IEEE also provides a variety of NESC resources online via the 'National Electrical Safety Code Zone'.

The NESC is a performance code that takes a consistent approach to the safety of overhead and underground electrical supply lines, power-related telephone and cable TV lines, and rail power and signal installations. It is a comprehensive document that covers all relevant topics from grounding, rotating equipment, storage batteries, transformers, conductors and circuit breakers, to switchgear, clearances, cable terminations, safety signs, protective clothing, and ladders. The 2007 Code includes changes in many areas, including:

  • Rounding numbers found in the rules
  • Metal grounding poles
  • Starting voltages and clearances
  • Grounding and insulation for guys
  • Clearances between transmission lines
  • Multiplex cable attachment to neutral brackets
  • Loading due to freezing rain and wind
  • Fiber-reinforced polymer elements
  • Worker loads
  • Equipment bonding
  • Arc exposure analysis
  • Antenna radiation exposure limits

In addition, the 2007 Code includes new appendices on loading and conductor movement, extreme wind loading, and maximum over-voltage at a worksite.

The NESC Handbook, Sixth Edition is edited by Allen Clapp, who has been involved in helping create the code for 35 years. The Handbook contains commentary that clarifies the Code and its requirements so users can apply the work rules it contains to actual situations. It also details how the 2007 Code differs from the 2002 version and what this means for users. The Handbook was developed for those involved in the electric and communication industries, including those involved in system design, construction, maintenance, inspection, standards development, and worker training.

Current information on the NESC is available on the Internet at the National Electrical Safety Code Zone. The Zone covers NESC Committee activities and provides the latest interpretations and developments in the Code. It also addresses NESC-related products and services, provides hot links to e-news sites dedicated to NESC coverage, and answers frequently asked questions about the Code. In addition, it has an interactive area for comments and questions, and offers a subscription to NESC Update, an e-newsletter on current NESC developments and industry applications.

The IEEE is the secretariat for the National Electrical Safety Code, which means it provides a home for the NESC Committee and supports its activities with a full range of administrative, logistical, publishing and other services. The IEEE also offers users comprehensive support in obtaining, understanding and working with the Code.
