The 2007 National Electrical Safety Code (NESC) Handbook, Sixth Edition, edited by Allen Clapp, is an essential
companion to the Code. It gives users insight into what lies behind the NESC's
rules and how to apply them. The Handbook was developed for use at many levels
in the electric and communication industries, including those involved in system
design, construction, maintenance, inspection, standards development and worker
training.
The Handbook also discusses how the NESC Committee has interpreted the rules in
the Code and responded to change proposals during the past 85 years. This allows
users to understand how questions they may have were dealt with in the past. The
Handbook looks at how the 2007 Code, with its many additions and revisions,
differs from the 2002 version and what this means for users. The 2007 Code
includes changes in a great 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
The 2007 National Electrical Safety Code Handbook also contains new appendices on loading and conductor movement,
extreme wind loading, and maximum over-voltage at a work site.
