Copper Compression Lug 350 kcmil

This Burndy copper compression lug accepts stranded copper conductors up to 350 kcmil. The belled straight barrel eases wire insertion and the tin-plated finish resists corrosion. It is rated for 35 kV maximum voltage and 194 degrees F operating temperature. Certified to CSA and UL 486A-486B standards for commercial electrical installations.

Single Hole 1/2 Inch Stud Limitation

The lug provides only one mounting hole sized for a 1/2 inch stud, so it cannot serve applications that require two-hole NEMA spacing or a different bolt diameter. The die code 1, 025 dictates the specific crimp tool setting, limiting compatibility to tooling that matches this code. Installers must verify that the stud size and single-hole pattern meet the busbar or equipment layout before purchase.

Tin-Plated Copper Barrel Durability

The solid copper body with tin contact finish delivers reliable conductivity and oxidation resistance in industrial environments. Belled barrel geometry reduces the risk of strand damage during insertion, supporting consistent crimp quality. UL listing and CSA certification confirm compliance with North American safety requirements for power distribution up to 35 kV.

Questions about this item

Should I select this 350 kcmil lug or a smaller size for my stranded copper wire?

Choose this lug when the conductor is 350 kcmil stranded copper; the belled barrel is built for that maximum size and the red colour code confirms the match.

What does the 35 kV rating mean once the lug is crimped in my panel?

The connection is UL listed for up to 35 kV, so it meets the dielectric requirement for medium-voltage equipment when installed with the correct die.

How does the 1/2 in stud hole and CSA/UL 486A-486B listing affect what I can bolt this to?

The single 1/2 in hole fits a standard 1/2 in bolt, and the dual UL 486A-486B plus CSA certification means the lug is accepted for both US and Canadian code-compliant installations.
