Burndy 4 AWG Copper Terminal

This Burndy terminal connects stranded copper conductors from 4 AWG up to 1 AWG. It is built for commercial electrical and industrial wiring where a single-hole mechanical lug is required. The copper body handles up to 600 V and 194 °F continuous temperature. Suitable for installers who need a reliable hex-head termination.

Hex-head eases install; verify wire and stud

The hex head allows standard wrench tightening without special tooling. Ensure the stranded copper falls within the 4 AWG to 1 AWG range and that the stud is 3/8 in with a 0.44 in clearance hole. Over-torquing can deform the 0.28 in thick tongue, so apply only the manufacturer-recommended torque. The single-hole design means no hole-spacing alignment is needed.

Check conductor size, voltage and temperature limits

Confirm the existing wire is stranded copper between 4 AWG and 1 AWG before ordering. Verify the circuit does not exceed 600 V and that ambient temperature stays below 194 °F. The 1 in tongue width and 2.19 in overall length must fit the available bus-bar or enclosure space. This terminal accepts only one conductor per lug.

Questions about this item

How do I confirm the 4 AWG copper terminal is seated correctly after crimping?

Inspect the hex head for full compression, verify the 0.44 in stud hole aligns with the 3/8 in bolt, and ensure the 0.28 in tongue thickness sits flush against the busbar with no visible gaps.

Does the package include the 3/8 in mounting bolt or heat-shrink tubing for the 600 V copper connection?

The box contains only the single-hole copper terminal rated for 4–1 AWG stranded wire; mounting hardware and insulation sleeving must be purchased separately.

Should I choose the 4 AWG terminal or a larger lug for a 1 AWG stranded copper run at 194 °F?

This terminal accommodates both 4 AWG minimum and 1 AWG maximum stranded copper, so one size covers the full range up to the 194 °F operating limit.
