Split-Bolt Connector for Copper Wire

The Burndy KS26 is a copper split-bolt connector designed for electrical and industrial wiring. It joins run conductors from 2 AWG to 2/0 AWG and tap conductors from 14 AWG to 2/0 AWG. The unplated copper body carries a maximum voltage rating of 35,000 V and meets CSA, UL 486A, UL 486B and UL 486D standards. It is suited for installers needing a code-compliant copper-to-copper splice or tap.

Verify Wire Sizes and Torque Tooling

Before ordering, confirm that both run and tap conductors fall within the stated AWG ranges and are copper. The connector requires a 1.05 in hex nut and a torque of 385 in-lb, so a calibrated torque wrench with the correct socket is necessary. Check that the 1.94 in length and 0.82 in width fit the available space in the enclosure or junction box. This item is not for aluminium conductors or for wire sizes outside the listed ranges.

Thermal and Electrical Performance

In normal use the copper body conducts current with minimal temperature rise when torqued to 385 in-lb. The unplated finish relies on proper contact pressure rather than plating to maintain low resistance. No active cooling or noise considerations apply to this passive component. RoHS compliance confirms restricted substance limits are met.

Questions about this item

What comes with the KS26 split-bolt connector and what must be purchased separately?

The connector body and its square-head bolt are supplied as one piece; copper conductors rated from 14 AWG up to 2/0 AWG are not included and must be sourced separately.

Which conductor range should I choose for a 2 AWG run and a 14 AWG tap?

The KS26 accepts a run wire from 2 AWG to 2/0 AWG and a tap wire from 14 AWG to 2/0 AWG, so that combination falls within the specified range.

What does the 35,000 V rating mean when the connector is installed in a panel?

It indicates the maximum voltage the copper body and unplated finish are certified to withstand under UL 486A, UL 486B and UL 486D when torqued to 385 in-lb.
