With the support of NEMA’s Electrical Connector Section, the ANSI C119 Accredited Standards Committee (ASC) for Electrical Connectors recently revised ANSI C119.4-2016 American National Standard for Electric Connectors—Connectors for Use between Aluminum-to-Aluminum and Aluminum-to-Copper Conductors Designed for Normal Operation at or below 93° C and Copper-to-Copper Conductors Designed for Normal Operation at or below 100° C.
Extensive editorial changes were made to the standard, which covers electrical and mechanical requirements for connectors used to make connections between aluminum-to-aluminum, aluminum-to-copper, and copper-to-copper conductors on distribution and transmission lines.
Significantly, testing methods and equipment requirements were removed, since all testing methods and equipment are now addressed in the new ANSI C119.0-2015 Testing Methods and Equipment Common to the ANSI C119 Family of Standards, a complimentary copy of which comes with ANSI C119.4-2016. The remaining performance standards and requirements unique to the C119.4 standard were reorganized under a new numbering format.
This revision also includes the addition of an optional set of performances requirements: shunt class connector devices in Annex E. The ANSI C119 SC4 subcommittee provided these requirements as a reference in response to users who have requested guidance for testing shunt devices.
This connector standard is the first of the ANSI C119 series to be published in the new format with the common tests now contained in ANSI C119.0 Testing Methods and Equipment Common to the ANSI C119 Family of Standards.
The ANSI ASC C119 committee develops and maintains standards for overhead connectors, sealed insulated underground connectors, insulation-piercing connectors, and non-sealed multiport connectors systems, and is also working on a new high-temperature utility connector standard. It actively seeks additional membership from the user and general interest membership categories in order to provide proper balance among the participants.
