One-Hole Compression Lug for 6 AWG Copper

The Burndy YA6CL3BOX is a straight-tongue compression lug designed for terminating 6 AWG stranded copper wire. Its single 5/16 inch stud hole suits panel connections in electrical and industrial installations. The barrel is colour-coded blue with die code 374 for quick tool matching and carries an inspection hole to verify full conductor insertion. It is UL Listed and CSA Certified for use up to 35 kV and a maximum operating temperature of 194 degrees Fahrenheit.

Blue colour code and inspection hole aid

The blue barrel marking and die code 374 let installers select the correct crimp die without cross-referencing charts. A built-in inspection hole confirms that the conductor is fully seated before the crimp is made, reducing the chance of a high-resistance joint. The standard-length barrel and straight tongue keep the profile compact for tight enclosures while the copper construction maintains conductivity. No additional software or accessories are bundled with this hardware item.

Crimp-only termination limits field rework

Because the lug uses a permanent crimp termination, the connection cannot be undone or adjusted once compressed; a faulty crimp requires cutting off the lug and fitting a new one. The single-hole pattern accepts only a 5/16 inch stud, so it cannot adapt to other bolt sizes without an adapter. Ratings top out at 35 kV and 194 degrees Fahrenheit, so applications above those limits need a different connector. The 0.52 inch tongue width also restricts use to terminal pads that accommodate that spacing.

Questions about this item

Will the crimped lug ever need re-crimping or replacement under normal service?

The lug is a permanent copper crimp connection; once installed with the correct die code 374 it does not require re-crimping or scheduled replacement.

What is the first limit reached during continuous operation at full load?

The maximum operating temperature of 194 Degrees F will be the first limit encountered under sustained current.

Does the copper lug generate noticeable heat or require extra cooling when carrying rated current all day?

Copper construction runs cool at rated load; no additional cooling is needed provided the crimp is made to specification and ambient temperature stays below 194 Degrees F.
