SKU CH-BBS5-KHF5F

Copper split-bolt connector joins 8 to 6 AWG conductors, rated to 35 kV with 165 in-lb torque

  • Product typeElectrical Connectors
  • Copper body handles 35 kV maximum voltage
  • Square head design accepts 165 in-lb torque
  • Fits 8 to 6 AWG run and tap conductors
  • Compact 0.98 in length suits tight installations
  • RoHS compliant for regulated environments

Connector for 8–6 AWG copper

The Burndy KS173 split-bolt connector joins solid or stranded copper conductors ranging from 8 AWG to 6 AWG. It is built for electrical and industrial wiring tasks where a reliable copper-to-copper joint is required. The unplated copper body suits standard indoor and outdoor installations.

Rated to 35 kV maximum voltage

This connector carries a maximum voltage rating of 35 kV, the single figure that determines whether it matches the system voltage. The square head measures 0.7 in across and the hex nut is 0.62 in, allowing standard tool engagement during installation.

Torqued to 165 in-lb for sustained hold

Proper tightening to 165 in-lb creates a stable clamp that resists loosening under thermal cycling and vibration. Overall length is 0.98 in and overall width is 0.62 in, giving a compact profile for tight enclosures. RoHS compliance and ARRA listing confirm regulatory suitability for long-term service.

Questions about this item

What does the 35 kV rating mean once this connector is installed in a real machine?

The 35 kV rating is the maximum voltage the copper split-bolt can withstand between conductors without breakdown, so it suits medium-voltage distribution and motor leads up to that level.

How does the 165 in-lb torque cap affect the connection in practice?

Tightening the square-head bolt to 165 in-lb clamps the run and tap wires (8-6 AWG copper) firmly enough to maintain low resistance and resist vibration loosening.

What physical space does the 0.98 in length and 0.62 in width need to fit or mount?

The connector occupies roughly 0.98 in by 0.62 in, so allow that clearance in a junction box or cable tray for the body and the 0.7 in square head to be accessed with a wrench.
