One-Hole Compression Lug for 1 AWG Copper

The Burndy YA1CLB is a one-hole compression lug designed for solid or stranded copper wire up to 1 AWG. It suits electrical and industrial wiring jobs that require a secure, code-compliant termination on a 5/16 inch stud. The short barrel and belled straight profile keep the connection compact inside panels or enclosures.

Install with standard compression tooling

Installers crimp the lug using a die matched to code 1 or 018; the green color code on the barrel confirms the correct die selection. Tin-plated copper resists oxidation during the crimp and in service. The single stud hole simplifies alignment, but the fixed 5/16 inch spacing means the lug cannot adapt to other bolt patterns without replacement.

Rated 35 kV with 194 °F temperature limit

The connector carries a maximum voltage rating of 35 kV and operates continuously up to 194 degrees Fahrenheit. It is CSA certified and UL listed to standards 486A-486B, covering wire sizes 1 AWG and 2 AWG. Headroom ends at the 1 AWG maximum wire size and the single-hole mounting; applications needing larger conductors or multi-hole patterns require a different lug.

Questions about this item

How can I confirm the lug is properly crimped after installation?

A correct crimp shows the die code 1 or 018 imprint on the barrel and the green color code visible on the connector body.

What is included with the YA1CLB and what must I supply separately?

The package contains the tin-plated copper lug only; you must provide 1 AWG or 2 AWG solid or stranded copper wire and a crimping tool with the matching die.

Which wire sizes does this lug accept?

It is rated for 1 AWG maximum and also listed for 2 AWG solid or stranded copper conductors.
