Burndy KS29 Split-Bolt Connector

The Burndy KS29 split-bolt connector joins copper conductors in electrical installations. It accepts run wires from 1 AWG to 250 kcmil and tap wires from 8 AWG to 250 kcmil. The unplated copper body provides a direct metal-to-metal connection for industrial and automotive wiring tasks.

Integration with copper wiring systems

This connector fits into builds using copper wire within the stated size range. The square head allows tightening with standard tools to reach the specified 650 in-lb torque. It frees installers from needing specialised crimping equipment for these conductor sizes.

Capacity up to 250 kcmil at 35 kV

The connector handles conductors up to 250 kcmil at a maximum voltage of 35 kV. It meets UL 467, UL 486 A/B, CSA and EU RoHS standards. It does not suit aluminium conductors or wires larger than 250 kcmil.

Questions about this item

What torque is required on the 1.36 in hex nut to secure the connection?

The split-bolt connector requires 650 in-lb of torque on the 1.36 in hex nut to ensure a proper copper-to-copper connection.

How much heat does the connector generate during continuous operation at its 35 kV rating?

The copper body and unplated finish conduct current without added resistance, so the connector itself does not generate significant heat beyond what the conductors carry.

What conductor sizes must I already have on hand for this connector to work?

You need copper conductors between 1 AWG and 250 kcmil for both run and tap wires; the connector accepts 1 AWG to 250 kcmil run and 8 AWG to 250 kcmil tap.
