Abstract

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.<br>This standard establishes the electrical and mechanical test requirements for electrical connectors. This standard is not intended to recommend operating conditions or temperatures.<br><strong>Purpose</strong><br>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.<br>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.
