SKU CH-E1BN-QGF06

A long-barrel splice for 300 kcmil wire made from tin-plated copper, measuring 4.34 in long with a 0.81 in outside diameter, and CSA certified and UL listed

  • Product typeWire Connectors
  • Tin-plated copper resists corrosion for lasting conductivity
  • Long 4.34 in barrel ensures secure splice on 300 kcmil wire
  • 81 in outside diameter fits standard tooling
  • CSA certified and UL listed for code-compliant installations

300 kcmil Long-Barrel Splice

This Burndy YS30 connector joins 300 kcmil conductors in automotive and industrial wiring. Tin-plated copper construction resists corrosion while meeting CSA and UL requirements. The 4.34 in barrel length provides ample contact area for a secure crimp. It suits electricians and maintenance crews needing a reliable, code-compliant splice.

Fits 0.81 in outside diameter

The white insulator identifies the connector in crowded panels and the 0.81 in outside diameter slides into standard raceways. No special tooling beyond a 300 kcmil die is required, freeing bench space for other tasks. Builders needing smaller gauges or insulated multi-port blocks should select a different series.

Questions about this item

Will the 300 kcmil splice handle continuous current without overheating?

The tin-plated copper barrel is rated for 300 kcmil conductors and both CSA and UL listings confirm it meets the temperature-rise limits for that gauge.

Does the long-barrel design run hotter or draw more power than a standard splice?

The connector adds no active power draw; its 4.34 in length and 0.81 in outside diameter simply provide extra crimp area while the tin-plated copper keeps resistance low.
