ForewordThis standard was developed in response to a need created by the rapid expansion of underground distribution systems. A key element that allowed this expansion to become a reality is the separable insulated conductor. This device provides for simple and inexpensive connection and switching to transformers and other equipment used in underground distribution. When separable insulated conductors became available@ the Institute of Electrical and Electronics Engineers (IEEE) and the National Electrical Manufacturers Association (NEMA) worked cooperatively to develop a document that defined the interfaces@ ratings@ and test conditions for the device. The success of that cooperative effort is apparent from both the vast number of these devices now in interchangeable use in the field and their enviable safety record. This cooperative effort continues due to the ongoing upgrading and changing nature of these underground systems and products. The recent cooperative effort has been provided by the ANSI C119.2 Subcommittee and the IEEE Working Group on Separable Connectors under the auspices of the Distribution Subcommittee of the Transmission and Distribution Committee of the IEEE Power Engineering Society. This revision reflects the following major additions: ?? An accelerated current-cycling test for 200 A insulated connectors ?? Production test requirements calling for test components to duplicate fit and voltage stress ?? Stacking dimension criteria for 200 A separable connectors?This standard establishes definitions@ service conditions@ ratings@ interchangeable construction features@ and tests for load-break and dead-break separable insulated connector systems rated 601 V and above@ 600 A or less@ for use on power distribution systems.
