ROSSLYN, VA — The National Electrical Manufacturers Association (NEMA) recently released a number of new standards. The most recent is HP 4-2000, Electrical and Electronic FEP Insulated High Temperature Hook-Up Wire, Types KT, K, and KK. This publi-cation covers specific requirements for fluorinated ethylene propylene (FEP) insulated solid standard wire, designed for internal wiring of high-reliability electrical and electronic equipment.
The organization has also released FB 1-2001, Fittings, Cast Metal Boxes, and Conduit Bodies for Conduit, Electrical Metallic Tubing and Cable. This standard replaces the 1993 edition and provides information concerning the construction, test, performance, and manufacture of fittings, cast metal boxes, and conduit bodies for conduit tubing and cable assemblies.
