Latest version of the National Electrical Safety Code available through IEEE

Piscataway, NJ, August 2, 2006 — The National Electrical Safety Code (NESC) has been updated and the latest version, the 2007 National Electrical Safety Code, is 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 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” found on their website here.

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 document that attempts to cover 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 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 range of administrative, logistical, publishing and other services. The IEEE also offers users comprehensive support in obtaining, understanding and working with the Code.
