Value Brand One-Hole Compression Lug 500 kcmil 1/2 in Stud Short

SKU CH-BJ81-2C6T4

Connects 500 kcmil copper wire to a 1/2 in stud with a UL-listed seamless copper barrel

  • TypeElectrical Connectors
  • Rated for 35 kV maximum voltage
  • UL Listed for safety compliance
  • Seamless copper barrel ensures strong crimp
  • Inspection hole allows visual verification
  • Fits 500 kcmil copper wire with 1/2 in stud

Electrical Connector for 500 kcmil Copper Wire

This one-hole compression lug connects a single 500 kcmil stranded copper conductor to a 1/2 inch stud. The seamless copper barrel is UL Listed and colour-coded brown with die code 87 for quick identification during installation. It suits electrical and industrial wiring tasks that require a secure crimp termination.

Thermal Rating and Electrical Capacity

The lug operates at temperatures up to 257 Degrees F and is rated for a maximum voltage of 35 kV. Its copper construction provides reliable conductivity under normal load without adding active cooling requirements. No noise or power draw is generated by the passive component itself.

Build Integration and Compatibility

The straight tongue measures 1.61 inches wide and includes an inspection hole to verify full conductor insertion. It requires a compatible crimp tool matched to die code 87 and a 1/2 inch mounting stud on the busbar or equipment pad. The single-hole design frees up space compared with multi-hole lugs in tight enclosures.

Questions about this item

How do I crimp the 500 kcmil lug onto the copper conductor using die code 87?

Strip the insulation to the correct length, insert the conductor fully into the seamless barrel until visible through the inspection hole, then apply the die 87 crimp tool with even pressure for a solid copper connection.

Will the brown color-coded copper lug need replacement if operated near the 257 °F maximum temperature?

The lug is UL Listed for continuous use up to 257 °F; sustained exposure at or above that limit can anneal the copper and degrade the crimp, so plan to inspect and replace if temperatures regularly reach the rating.

At what voltage does the 35 kV rating become the limiting factor during sustained load?

The lug is rated for 35 kV maximum; insulation breakdown or tracking can occur first if the system voltage approaches that level under continuous operation, so verify the applied voltage stays well below the rating.
