  • Length3.400
  • MaterialCopper
  • TypeCommercial
  • UL 486A-486B listed for code-compliant installations
  • 35 kV rating supports high-voltage applications
  • Long barrel design ensures secure crimp connections

Copper Compression Lug for 250 kcmil Wire

This Burndy lug connects a single 250 kcmil stranded copper conductor to a half-inch stud. The long barrel design provides extended crimp area for secure termination in commercial electrical installations. Yellow colour coding and die code 16 identify the correct tooling. UL 486A-486B and CSA certifications confirm compliance with North American safety standards.

Straight Tongue and Inspection-Free Design

The straight tongue measures 1.11 inches wide and aligns directly with the stud hole for straightforward mounting. No inspection hole is present, so visual verification of wire insertion must occur before crimping. Rated for 35 kV maximum voltage and 194 degrees F operating temperature, the copper body resists corrosion in demanding environments.

Crimp Installation with Matched Die

Installation requires a compression tool equipped with a die code 16 set matched to the yellow colour code. Using an incorrect die or insufficient pressure creates a high-resistance joint that can overheat. The fixed 250 kcmil wire range allows no flexibility for smaller or larger conductors. Builders needing multi-hole patterns or angled tongues must select a different lug.

Questions about this item

Will the copper lug need any maintenance or replacement after it is crimped?

The lug is a single-use crimp fitting; once the 250 kcmil conductor is compressed with die code 16 it forms a permanent joint that does not require further maintenance.

What is the first limit reached under continuous electrical load?

The lug is rated for a maximum operating temperature of 194 degrees Fahrenheit, so sustained current that pushes the connection above that temperature would be the limiting factor.

Does the lug generate noticeable heat or noise when it carries current all day?

The copper body is a passive conductor with no moving parts, so it produces no noise and only the normal resistive heat that stays within the 194-degree-Fahrenheit rating.
