  • TypeElectrical Connectors
  • UL 486A-486B listed for code-compliant copper connections

Two-Hole Compression Lug 4 AWG

This Burndy compression lug connects 4 AWG stranded copper conductors to a 1/4 inch stud using a standard barrel. The straight tongue measures 0.5 inches wide with a 0.625 inch hole center-to-center spacing and includes an inspection hole for visual verification.

Verify Conductor Size and Stud Fit

Confirm the wire is 4 AWG stranded copper and that the mating stud is 1/4 inch before ordering. The lug is rated for 35 kV AC maximum voltage and 194 degrees F operating temperature, so ensure the circuit parameters stay within these limits.

Upgrade from Single-Hole or Undersized Lugs

The two-hole pattern provides a more secure mechanical connection than single-hole alternatives and resists vibration loosening in industrial or automotive applications. It replaces older lugs lacking CSA certification and UL 486A-486B listing where code compliance is required.

Questions about this item

Does the Burndy YA4CL2TC14 lug come with mounting hardware or crimping dies, or must those be purchased separately?

The lug is supplied as the connector only; 1/4 in mounting bolts and a 346/8 die set for the crimp tool are not included and must be sourced separately.

How do I choose between the different stud sizes or barrel lengths that Burndy offers for 4 AWG copper wire?

This model is fixed to a 1/4 in stud, standard barrel and straight tongue; other stud diameters or long-barrel versions carry different part numbers and are not interchangeable with YA4CL2TC14.

What does the 35 kV AC rating mean when the lug is crimped onto 4 AWG copper in a panel?

The 35 kV AC rating is the maximum voltage the copper connector assembly can withstand after a proper crimp; it does not change the ampacity of the 4 AWG conductor itself.
