  • Product typeElectrical Connectors
  • Copper construction ensures high conductivity
  • Seamless barrel design adds mechanical strength
  • CSA certified and UL listed for safety compliance
  • Rated for 600 V AC and 300 °F operating temperature
  • Fits 3/0 AWG copper wire with 3/8 in stud size

Copper compression lug for 3/0 AWG

This one-hole compression lug accepts stranded copper wire sized at 3/0 AWG and terminates on a 3/8 in stud. The seamless copper barrel carries a long barrel design with an orange colour code and die code 50. It is UL Listed and CSA Certified for electrical installations up to 600 V AC.

Thermal and electrical ratings

The connector is rated for a maximum operating temperature of 300 Degrees F and a maximum voltage of 600 V AC. A crimp termination style provides a secure mechanical and electrical bond without solder. The straight tongue angle and 0.92 in tongue width suit standard busbar or lug mounting patterns.

Upgrade from smaller lugs or split barrels

Installers moving from a smaller barrel size or a two-hole lug with a seam will gain the current capacity of 3/0 AWG in a single seamless barrel. The jump is worth it when the circuit requires the full ampacity of 3/0 copper and a single 3/8 in stud mounting point. Buyers needing a two-hole pattern or a different stud size should select an alternative lug.

Questions about this item

How do you install the Value Brand One-Hole Compression Lug on 3/0 AWG copper wire, and what is the common mistake?

Strip the conductor to the correct length, insert it fully into the seamless barrel, and crimp using a die coded 50; the step often missed is verifying the wire reaches the barrel end before crimping.

What maintenance or replacement will this compression lug need over time?

The lug itself is maintenance-free, but inspect the crimp joint periodically for overheating signs; replace the connector if discolouration, corrosion, or mechanical damage appears.

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

The 300 °F maximum operating temperature is the first constraint; sustained loads that push the connection beyond this rating will degrade the copper barrel before the 600 V AC voltage limit is reached.
