Buchanan BTC500-1/0 Insulation-Displacement Wire Connector 500 kcmil 2

SKU CH-4WVG-XHXQX

Insulation-displacement connector joins 2/0–500 kcmil run and 1/0–350 kcmil tap wires up to 600 V without stripping

  • Length3.9"
  • TypeInsulation-Piercing
  • Insulation-displacement design eliminates stripping time
  • Accepts run wires from 2/0 AWG to 500 kcmil
  • Tap range covers 1/0 AWG through 350 kcmil
  • UV-stable polymer housing rated to 194 °F
  • Rated for 600 V maximum voltage

Insulation-Piercing Connector for Large Conductors

The Buchanan BTC500-1/0 is an insulation-displacement wire connector rated for a maximum run conductor of 500 kcmil and a maximum tap conductor of 350 kcmil. It accepts a single run wire from 2/0 AWG up to 500 kcmil and a single tap wire from 1/0 AWG up to 350 kcmil. The connector is designed for electrical and industrial wiring applications requiring a run-tap configuration.

UV-Stable Polymer Housing With 3.9 Inch Length

The black connector body uses UV-stable polymer insulation material suitable for outdoor exposure. Its 3.9 inch length accommodates the large conductor range while the insulation-piercing design eliminates the need to strip wire insulation before installation. Maximum run wire insulation diameter is .925 in and maximum tap wire insulation diameter is .8 in for secure contact.

600 Volt Maximum Rating at 194 Degrees F

The single specification that determines suitability is the 600 V maximum voltage rating combined with a 194 Degrees F maximum operating temperature. Installations exceeding either limit cannot use this connector. It is not for buyers who need higher voltage ratings or multi-conductor tap configurations beyond the single conductor per side design.

Questions about this item

What voltage and temperature does the 500 kcmil run rating actually allow?

The connector is rated for 600 V maximum and a 194 °F maximum operating temperature on the run side.

What are the largest insulation diameters that still fit the run and tap ports?

Run port accepts up to .925 in insulation diameter; tap port accepts up to .8 in.

How is the connection made without stripping, and what torque step is often missed?

Tighten the set-screw until it shears off — the shear-head is the built-in torque indicator that installers sometimes forget to finish.
