In an attempt to establish a national standard to improve product quality as well as dimensional and physical characteristics for users of galvanized ground rods, the National Electrical Manufacturers Association (NEMA), Rosslyn, Va., recently released ANSI/NEMA GR 1-2001, Grounding Rod Electrodes and Ground Rod Electrode Couplings.
The ANSI-approved standard, which replaces NEMA GR 1-1997, provides information concerning the construction, testing, performance, and manufacture of ground rod electrodes and ground rod electrode couplings. It includes information about materials, construction, and performance of copper bonded, hot-dip galvanized ground rod electrodes.
The standard may be purchased at www.global.ihs.com.
