This standard establishes definitions, service conditions, ratings, interchangeable construction features, and tests for loadbreak and deadbreak separable insulated connector systems rated above 600 V, 600 A or less, for use on power distribution systems. Revision to the standard are needed to provide the user with stacking dimensions of assembled 200 A and 600 A medium voltage insulated deadbreak connectors. New test procedures will improve reliability and provide repeatable results for both user and manufacturer evaluations. Revision Standard - Superseded. Revision of IEEE Std 386-2000 Definitions, service conditions, ratings, interchangeable construction features, and tests are established for loadbreak and deadbreak separable insulated connector systems rated above 600 V and, 600 A or less, for use on power distribution systems.
