ROSSLYN, Va.—The National Electrical Manufacturers Association (NEMA) published new testing requirements in ANSI C119.5-2018 American National Standard for Electric Connectors—Insulation-Piercing Connector Systems, Rated 600 V or Less (Low Voltage Aerial Bundled Cables and Insulated and Non-Insulated Line Wires).

"In this edition of C119.5, the common test for the C119 family of standards has been removed and replaced by references to the document C119.0 Testing Methods and Equipment Common to the ANSI C119 Family of Standards. Users of this standard should also acquire C119.0," said Andy Zwit, Technical Marketing Manager, ILSCO Corporation and Chair of the C119 Subcommittee for Connectors.  

Developed by the ANSI C119 Subcommittee for Connectors, the revised ANSI C119.5-2018  covers insulation-piercing connectors used for making electrical connections between insulated, insulated-to-bare, and bare-to-bare conductors rated 600 V or less and 90°C (low-voltage aerial bundled cables and bare and insulated line wires) on overhead distribution lines for electric utilities.

ANSI C119.5-2018 is available in hard copy or as an electronic download for $96 on the NEMA website. 

ANSI C119.0-2015 is available at no cost on the NEMA website.
