Burndy KC25 Bolt Connector Bronze

The Burndy KC25 is a grounding split bolt connector made from leaded bronze alloy. It accepts solid conductors from 2 to 1/0 AWG and stranded conductors from 2 to 2/0 AWG for a single grounding wire. The mechanical connector is UL Listed and UL467 compliant for direct burial applications.

Installation Limits and Standards

The connector requires an installation torque of 480 in-lb using a 1/2 in.-13 thread stud. It carries UL Listed and UL Listed-Direct Burial markings, confirming suitability for underground use. The overall length measures 1.93 in and the width is 3/4 in, defining the space needed for termination.

Build and Daily Implications

The leaded bronze alloy body resists corrosion in buried or exposed environments. A single bolt mechanism clamps the conductor without specialised crimping tools, allowing field installation with standard hand tools. The K2C and KC designations identify the connector family for specification matching. Not for buyers needing multi-wire taps or connectors rated for larger conductor sizes.
