ANSI C119.4-2004 pdf download American National Standard for Electric Connectors— Connectors for Use Between Aluminum-to-Aluminum or Aluminum-to-Copper Conductors
1 Scope and Purpose
1.1 Scope
This standard covers connectors used for making electrical connections between aluminum-to-aluminum or aluminum-to-copper conductors used on distribution and transmission lines for electric utility.
This standard establishes the electrical and mechanical test requirements for electrical connectors. This standard is not intended to recommend operating conditions or temperatures.
1.2 Purpose
The purpose of this standard is to give reasonable assurance to the user that connectors meeting the requirements of this standard will perform in a satisfactory manner, provided they have been properly selected for the intended application and are installed in accordance with the manufacturer’s recommendations. The service operating conditions and the selection of the connector class is the responsibility of the user.
Although there are 12 possible combinations of electrical and mechanical classes listed in this standard, it is intended that four to six combinations will meet the usual requirements for a given range of conductor sizes. This does not, however, prohibit other combinations.
1.3 Definitions
bolted-type connector: A connector in which the contact between the conductor and the connector is made by pressure exerted by one or more clamping bolts.
conductor: Conducting material used as a carrier of electric current.
connector: A device joining two or more conductors to provide a continuous electrical path.
range-taking connector: Connector designed to accept multiple conductor sizes.
run conductor (main): A continuous conductor from which other conductors branch.
splice: A connector joining two conductor ends.
tang (pad): The flat portion of a connector used for electrical connection.
tap conductor: A conductor that branches off from the run conductor.
tap connector: Connector joining a tap conductor to a run conductor without breaking the run conductor.
terminal connectors: A connector that joins a conductor(s) to an electrical device.
