Burndy KS223 Split-Bolt Connector

The Burndy KS223 is an unplated copper split-bolt connector designed to join copper conductors. It accepts a run wire from 6 AWG up to 2 AWG and a tap wire from 6 AWG to 3 AWG. Rated for 35 kV maximum voltage, it uses a square head with a 0.74 in hex nut and requires 275 in-lb of torque.

Suitable for copper-to-copper splicing

This connector suits electricians and maintenance crews making permanent copper splices up to 35 kV. It is not for aluminium conductors, mixed-metal joints, or tap wires larger than 3 AWG. Buyers needing insulated or tin-plated bodies should look at other connector types.

Simple hand-tool installation with torque control

Install by stripping the conductors, inserting them into the bolt groove, and tightening the square-head nut to 275 in-lb using a calibrated torque wrench. The 1.5 in overall length fits tight enclosures. Common errors are under-torquing, using non-copper wire, or exceeding the stated AWG ranges.

Questions about this item

What wire sizes must I already have on hand to use this split-bolt connector?

The connector accepts run conductors from 6 AWG up to 2 AWG and tap conductors from 6 AWG up to 3 AWG, so you need copper wire in those ranges.

Will the square-head nut fit the 0.74 in hex socket I already use for older Burndy connectors?

Yes, the nut on this KS223 measures 0.74 in across flats, matching the standard hex size used on compatible models such as the SC2.

How can I confirm the joint is torqued correctly after installation?

Tighten the square-head nut to 275 in-lb; when the torque wrench clicks at that value the connection is secured to the manufacturer’s specification.
