Burndy KSA4 Aluminum Split Bolt Connector, Tin Plated, UL486B Listed

The Burndy KSA4 Aluminum Split Bolt Connector, Tin Plated, UL486B Listed is a mechanical Run/Tap connector family built for reliable splicing and tapping between Al/Al, Al/Cu, or Cu/Cu conductors. Constructed of aluminum with a tin-plated finish, the KSA4 family is available across a range of maximum conductor sizes — from Up to 6 AWG and Up to 4 AWG through Up to 2 AWG, Up to 1/0 AWG, Up to 2/0 AWG, Up to 4/0 AWG, and Up to 500 MCM — so installers can select the exact split bolt for their run and tap conductor pairing. Every option in the family shares the same aluminum body, tin-plated finish, and UL486B Listing for verified mechanical and electrical connector performance across commercial and industrial electrical systems.

Key Features

  • Maximum Conductor Size Range: Choose from Up to 6 AWG, Up to 4 AWG, Up to 2 AWG, Up to 1/0 AWG, Up to 2/0 AWG, Up to 4/0 AWG, or Up to 500 MCM to match the run and tap conductors on the job.
  • Conductor Compatibility: Rated for Al/Al, Al/Cu, or Cu/Cu conductor combinations, giving installers flexibility across mixed-metal terminations without needing separate connectors for each pairing.
  • Durable Construction: Aluminum body provides a lightweight, corrosion-resistant split bolt connector suited for demanding electrical environments.
  • Finish: Tin-plated surface helps reduce oxidation at the connection point and supports consistent, long-term electrical contact between dissimilar metals.
  • Type: Run/Tap configuration allows a continuous run conductor to be tapped without cutting or splicing the main line, streamlining panel and splice-box wiring.
  • Product Line: Part of Burndy's Servit® and Tritap™ mechanical connector families.
  • Listing: UL486B Listed, confirming verified mechanical and electrical connector performance across the entire size range.

Burndy KSA6 – Frequently Asked Questions

1) Can the Burndy KSA4 split bolt be used to connect aluminum to copper wire?
Yes. The KSA4 is rated for Al/Al, Al/Cu, or Cu/Cu conductor combinations, so one connector handles mixed-metal terminations. The body is aluminum with a tin plating that cuts oxidation at the contact point, which is what makes the dissimilar-metal connection viable.
2) What wire sizes does the Burndy KSA4 split bolt connector take?
Overall conductor range on the KSA4 is 8-4 AWG. Run conductors can be 8-4 AWG stranded copper or 8-4 AWG aluminum; taps can be 10-4 AWG copper, 10-4 AWG solid copper, or 8-4 AWG aluminum. The max run to min tap combination is #4 Str to #10 Sol.
3) I need a split bolt for larger feeders than #4. What Burndy model do I order?
The KSA4 tops out at 4 AWG. The same Burndy aluminum split bolt family runs larger in KSA1/0, KSA2/0 and KSA4/0, and smaller in KSA6. KSA2 sits between the 4 and the 1/0. Pick by the largest run conductor you are landing.
4) Do I have to cut the main conductor to land a tap with a KSA4?
No. The KSA4 is a Run/Tap split bolt, so the continuous run conductor lays in the bolt slot uncut and the tap is clamped against it. That keeps the main line intact in a panel or splice box.
5) Is the Burndy KSA4 the same thing as a Servit or Tritap connector?
Yes. The KSA4 belongs to Burndy's Servit and Tritap mechanical connector lines, so a spec calling for a Servit or Tritap run/tap split bolt in the 8-4 AWG range is asking for this part.
6) Does a KSA4 split bolt need to be taped or insulated after it is made up?
The KSA4 is a bare mechanical connector, not an insulated one, so the completed splice has to be insulated in the field with tape or a connector cover to the level required by the circuit.
7) Will an aluminum split bolt corrode in a damp vault or outdoor pull box?
The KSA4 body is aluminum with a tin-plated surface, which is what slows oxidation at the connection point and keeps contact stable over time. Aluminum also keeps the connector light on larger conductor bundles.
