Buchanan

Buchanan BTC500-4 Insulation Displacement Connector 500 kcmil 600 V Black

SKU CH-ASJE-37DBJ

Connects 2/0–500 kcmil run wires to 4–4/0 AWG tap wires at 600 V using insulation-piercing contacts

  • Length3.9"
  • TypeInsulation-Piercing
  • Insulation-displacement design speeds installation without stripping
  • UV-stable polymer housing resists outdoor degradation
  • 600 V rating covers standard low-voltage power circuits
  • Accepts run wires from 2/0 AWG up to 500 kcmil
  • Tap range 4 AWG to 4/0 AWG for flexible branching

Purpose & fit

This Buchanan BTC500-4 insulation displacement connector joins a single run conductor from 2/0 AWG up to 500 kcmil with a single tap conductor from 4 AWG to 4/0 AWG. It is rated for 600 V and uses a UV-stable polymer body that withstands temperatures up to 194 Degrees F. The black finish identifies the connector in outdoor or industrial wiring jobs where insulation piercing speeds up installation without stripping.

Upgrade path

It replaces traditional bolted lugs or split-bolt taps that require stripping, taping and torque tools on large conductors. The jump is worth it when you need a faster, tool-free tap on existing 2/0 AWG to 500 kcmil runs and can accept a single 4 AWG to 4/0 AWG branch. It is not for installers who need multi-tap blocks, in-line splices or connectors rated above 600 V.

Compatibility checklist

Verify the run conductor insulation diameter does not exceed .925 in and the tap conductor insulation diameter stays within .46 in. Confirm both conductors are solid or stranded copper within the stated AWG or kcmil ranges and that the system voltage is 600 V or less. The connector length is 3.9 in, so ensure the enclosure or tray provides enough straight-line clearance for the insulation-piercing mechanism.

Questions about this item

What is the largest run-wire insulation diameter the Buchanan BTC500-4 can accept?

The connector accommodates run-wire insulation up to 0.925 in, so the cable jacket must not exceed that diameter for a proper pierce.

Which installation step is most often missed when fitting this insulation-piercing connector?

Tightening the set screws to the specified torque is the step installers skip; without it the piercing teeth do not fully penetrate the insulation.

How can I tell when the UV-stable polymer body needs replacement?

Replace the connector if the black housing shows chalking, cracking or deformation after prolonged sun exposure, as the 194 °F temperature rating assumes intact insulation.
