Burndy KS203 Split-Bolt Connector 8-4 AWG

SKU CH-GSAE-8G92S

Split-bolt connector joins 8 to 4 AWG copper conductors with a 35 kV rating and 165 in-lb torque spec

  • Product typeElectrical Connectors
  • Connects copper conductors from 8 AWG to 4 AWG
  • Unplated copper body resists corrosion in harsh environments
  • Square head design allows secure tightening with standard tools
  • Rated for 35 kV maximum voltage in power applications
  • RoHS compliant and meets ARRA standards for regulated projects

Burndy KS203 Split-Bolt Connector

The Burndy KS203 is a copper split-bolt connector designed for joining solid or stranded copper conductors in electrical installations. It suits electricians and maintenance crews who need a reliable mechanical splice for power distribution circuits. The unplated copper body provides direct metal-to-metal contact for consistent conductivity. It meets ARRA and EU RoHS compliance requirements for regulated projects.

Conductor Range 8 to 4 AWG

The single specification that determines fit is the approved conductor range covering both run and tap wires from 8 AWG up to 4 AWG. This range defines whether the connector matches the cable sizes on the job. Using conductors outside this window can compromise the mechanical grip and electrical integrity of the joint. Verify wire gauges before ordering to ensure compatibility.

Capacity And Headroom

Rated for up to 35 kV maximum voltage, the connector handles medium-voltage splicing duties within its wire-range limits. The 165 in-lb torque specification sets the tightening force needed to secure the connection without damaging the copper strands. Headroom runs out when conductor sizes exceed 4 AWG or when voltage demands surpass the 35 kV rating, requiring a larger or higher-rated connector instead.

Questions about this item

What does the 35 kV rating mean once the connector is installed?

It means the connector is rated to handle up to 35 kV when properly torqued to 165 in-lb on copper conductors between 8 and 4 AWG.

What standard governs the 0.68 in hex nut and how does it limit the installation?

The square-head bolt uses a 0.68 in hex nut that must be tightened to 165 in-lb, which sets the mechanical and electrical limit for the 8-4 AWG copper range.

What physical space does the 1.2 in overall length need to fit inside a panel or enclosure?

The connector measures 1.2 in overall length, so the enclosure must provide at least that much straight clearance for the body and the square-head bolt.
