Small bare copper butt splice connector, tin-plated, about 0.63 inches long

Panduit

Panduit BS10-L Butt Splice Connector 10 AWG Copper

SKU CH-G330-E903C

A tin-plated copper butt splice for crimping 12-10 AWG wires, rated to 302 °F and 2,000 V with UL 486C and CSA C22.2 No. 65 compliance

  • Product typeElectrical Connectors
  • Handles 10 AWG wire with secure crimp termination
  • Brazed seam construction prevents barrel separation under load
  • Tin-plated copper body resists corrosion for lasting conductivity
  • Rated 2,000 V and 302 °F for demanding electrical environments
  • CSA C22.2 No. 65 and UL 486C listed for code compliance

What this butt splice connector does

The Panduit BS10-L is a copper butt splice for joining solid or stranded conductors. It accepts wire sizes from 12 AWG up to 10 AWG and is rated for 2,000 V maximum voltage. The crimp termination creates a secure joint without solder.

How the bare metal design changes the job

With no insulation sleeve, the barrel stays exposed after crimping. The tin-plated copper body resists corrosion and the brazed seam prevents the barrel from splitting under pressure. Installers must add separate heat-shrink or tape if insulation is required by code.

Capacity limits for typical wiring tasks

The 0.14 in barrel inside diameter fits 10 AWG conductors comfortably while the 0.63 in overall length keeps the splice compact in tight boxes. Operation up to 302 Degrees F covers most automotive and industrial environments. It is not suited for wires larger than 10 AWG or for applications needing built-in insulation.

Questions about this item

Will the tin-plated copper barrel need replacement after repeated crimping cycles?

The brazed-seam copper barrel with tin plating is designed for a single permanent crimp; it is not intended to be re-crimped or reused once installed.

What temperature limit applies when the splice runs continuously at 2,000 V?

The maximum operating temperature is 302 °F, which is the first thermal limit reached under sustained full-voltage load.

How much heat does the bare copper body generate during all-day operation at 10 AWG?

With no insulation and a 0.14 in barrel ID, the connector dissipates heat directly into the surrounding air; temperature rise stays within the 302 °F rating when crimped to 10–12 AWG copper.
