POWER FIRST

POWER FIRST 22EZ42 Crimp Wire Connector 400 kcmil Blue

SKU CH-V15E-NX3ZA

A seamless tin-plated copper splice connector for 400 kcmil stranded copper wire rated to 600 V and 300 °F

  • Connects 400 kcmil copper cable securely
  • Tin-plated seamless barrel resists corrosion
  • UL 486A-486B listed for 600 V work
  • Rated to 300 °F operating temperature
  • Blue color code matches die 76

400 kcmil Copper Splice Connector

The POWER FIRST 22EZ42 is a long-barrel copper splice rated for 400 kcmil stranded copper conductors. Tin-plated barrel and seamless construction meet ANSI and UL 486A-486B standards for 600 V applications. Designed for electricians making permanent inline connections in commercial or industrial wiring.

Suited for single-conductor 400 kcmil copper splices

Installers needing a code-blue connector for 400 kcmil stranded copper will match the die code 76 and eight-crimp requirement. Not for smaller wire sizes, multi-conductor bundles, aluminum conductors, or voltages above 600 V. Buyers who need insulated barrels or different colour codes should look elsewhere.

Sustained load up to 300 °F within 3.79 in barrel

Tin-plated copper barrel maintains conductivity at the rated 300 °F maximum operating temperature across the full 3.79 in length. Seamless design resists splitting during repeated thermal cycles. RoHS-compliant materials support long-term environmental compliance in fixed installations.

Questions about this item

What crimp tool and die code are required to install the 22EZ42 connector on 400 kcmil copper wire?

Use a crimp tool that accepts die code 76 and apply eight crimps per the manufacturer specification for a secure long-barrel splice.

Can the 22EZ42 connector be used with existing 600 V copper wiring rated for lower temperatures?

Yes, the connector is rated 600 V and 300 °F, so it is compatible with standard 600 V copper circuits operating at or below that temperature limit.

How can I verify the 22EZ42 splice is correctly completed after crimping?

Confirm eight distinct crimp impressions are visible, the barrel seats fully on the 400 kcmil conductor, and the blue color code matches the die code 76 marking.
