Aluminium Split-Bolt Connector

The Burndy KSA2/0 is a tin-plated aluminium split-bolt connector designed to join aluminium or copper conductors in electrical installations. It accommodates run wires from 2 AWG to 2/0 AWG and tap wires from 8 AWG to 2/0 AWG. The connector carries CSA certification and meets UL 468A, UL 486B and UL 486D standards for code-compliant work.

Verify Conductor Sizes and Torque Tool

Before ordering, confirm that both the run and tap conductors fall within the stated AWG ranges and are aluminium or copper. The square-head hex nut measures 1.12 in across flats, so ensure the correct socket or wrench is available to reach the specified 385 in-lb torque. The connector is rated for a maximum of 35 kV and an operating temperature of 194 Degrees F.

Tin-Plated Body and Square-Head Nut

The aluminium body receives a tin-plated finish that resists oxidation in damp or industrial environments. A square-head nut allows positive engagement with a standard socket, reducing the risk of rounding during high-torque tightening. Overall length is 1.92 in and width is .88 in, keeping the profile compact inside junction boxes or panel enclosures.

Questions about this item

What comes with the KSA2/0 split-bolt and what must I supply?

The connector ships as a single tin-plated aluminium body with a square-head bolt and 1.12 in hex nut. You supply the 2 AWG to 2/0 AWG run conductor, 8 AWG to 2/0 AWG tap conductor, and a torque wrench capable of 385 in-lb.

How do I choose between the listed run and tap size ranges?

Match the run wire to the 2 AWG minimum or 2/0 AWG maximum, and the tap wire to the 8 AWG minimum or 2/0 AWG maximum; both aluminium and copper conductors are accepted within those limits.

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

It certifies the joint for continuous operation up to 35 kV provided the conductors are within the stated size range, torqued to 385 in-lb, and the assembly stays below 194 °F.
