Copper Compression Lug for 300 kcmil Wire

This Burndy copper lug accepts stranded copper conductors up to 300 kcmil and also fits 250 kcmil and 4/0 AWG sizes. A single 1/2 inch stud hole secures the connection in commercial and industrial electrical installations. The belled straight barrel eases wire insertion during crimping.

Rated for 35 kV and 194 Degrees F Operation

The tin-plated copper body is UL Listed and CSA Certified to UL 486A-486B standards. Maximum operating temperature reaches 194 degrees Fahrenheit while the assembly withstands up to 35 kilovolts. These ratings suit heavy-duty power distribution panels and feeder circuits.

Single Hole Mounting Limits Configuration

Only one mounting hole is provided, so the lug cannot be used where a two-hole NEMA pattern is required. Installers needing dual-hole clearance or a different stud diameter must select an alternative connector.

Questions about this item

How do I install this 300 kcmil copper lug and what step is often missed?

Strip the stranded copper wire to the correct length, insert it fully into the belled barrel, then crimp with a die marked 024 or die code 1; the step often missed is verifying full insertion before crimping.

What maintenance or replacement will this tin-plated copper lug need over time?

Inspect the tin-plated contact for oxidation or discoloration after thermal cycling; replace the lug if the barrel shows cracking, severe discoloration, or if the crimp joint becomes loose.

What limit appears first when this lug runs continuously at high load?

The 194 °F maximum operating temperature is the first limit reached under sustained current; exceeding it can degrade the tin finish and weaken the crimp connection.
