The Conversions Tech long barrel compression lug is a tin-plated copper termination for 3 AWG conductors with a 5/16-inch bolt mounting. The extended barrel length provides increased contact surface area for improved mechanical retention and electrical conductivity in power distribution panels, industrial machinery, and construction electrical systems. White color code identifies the 3 AWG conductor size for quick field verification during installation.

FAQ

What crimping tool is required for this 3 AWG long barrel lug?

Use a compression tool with dies rated for 3 AWG copper and compatible with long barrel lug profiles. Verify die index marks align with barrel length for full compression.

Is this lug rated for 90°C conductor ampacity?

Yes. The 90°C temperature rating supports full ampacity of 90°C rated 3 AWG copper conductors per NEC tables, limited by the 170A maximum amp rating of the lug itself.

Can this lug be used in wet or corrosive environments?

The tin-plated copper construction provides corrosion resistance. Verify specific environmental suitability with your application requirements and applicable code provisions.
