NEMA Publishes ANSI/NEMA GR 1-2007 Grounding Rod Electrodes and Grounding Rod Electrode Couplings

The National Electrical Manufacturers Assn.'s ANSI/NEMA GR 1-2007 provides practical information concerning materials, construction, testing, performance and manufacture of copper-bonded ground rod electrodes, zinc-coated ground rod electrodes, and stainless steel-clad ground rod electrodes.


The National Electrical Manufacturers Assn. (NEMA), Rosslyn, Va.,stainless steel-clad ground rod electrodes.

This ANSI-approved standard applies to electrodes and electrode couplings that function according to the National Electrical Code (NEC) and the National Electrical Safety Code (NESC). It covers design and performance requirements and provides recommendations for selections and use. It also includes information for electrode products that have been successfully used for many years but are not defined within NEC or NESC.

The contents and scope of GR 1-2007 may be viewed, and a hard copy or electronic copy purchased for $58, by visiting NEMA’s website at , or by contacting IHS at 800-854-7179 (within the U.S.), 303-397-7956 (international), or 303-397-2740 (fax).
