This edition of NFPA 780, Standard for the Installation of Lightning Protection Systems, was prepared by the Technical Committee on Lightning Protection and acted on by NFPA at its May Association Technical Meeting held May 23–26, 2004, in Salt Lake City, UT. It was issued by the Standards Council on July 16, 2004, with an effective date of August 5, 2004, and supersedes all previous editions.
This edition of NFPA 780 was approved as an American National Standard on August 5, 2004.
The 2004 edition also contains a number of technical revisions throughout the standard. These include the following: a main conductor, solid strip, was added for Class II material requirements for ordinary structures exceeding 75 ft in height; handrails can be used as a substitute for down conductors; additional separation between ground rods is required where multiple ground rods are used; additional guidance is provided for those instances where it is necessary to install the grounding conductor directly on bedrock; the section entitled Surge Suppression was entirely rewritten; titanium strike termination devices can now be used; and in Annex K the term Faraday cage was replaced with metallic cage.
