Abstract

This Standard applies a method of connection and switching of transformers and other electrical equipment in distribution systems using special flexible cable connectors.

Scope

This Standard specifies requirements for load-break and dead-break separable insulated connectors and ancillary equipment for use on power distribution systems at alternating voltages above 1 kV.
The Standard applies to separable insulated connectors rated at not more than 1250 A.
NOTE: Load-break connectors are available only for the lower current ratings. The purchaser should obtain information from manufacturers on available current ratings.
