The 300 MCM Copper Compression Lug is a one-hole, long-barrel terminal connector engineered for high-current power distribution terminations. Designed for 300 MCM copper conductors with a 3/8-inch stud interface, this lug provides secure mechanical and electrical connections in switchgear, panelboards, industrial equipment, and utility infrastructure. The long barrel configuration supports multiple crimp zones for enhanced pull-out strength and consistent contact resistance.

FAQ

What crimping die is required for this lug?

Use die index I-66 with a compression tool rated for 300 MCM copper conductors. Proper die selection ensures full barrel compression and maintains the 35 kV voltage rating.

Is this lug rated for wet locations?

The tin-plated copper construction provides corrosion resistance. Verify specific environmental suitability against local code requirements and installation conditions.

Can this lug be used with aluminum wire?

No. This lug is engineered specifically for 300 MCM copper conductors. Using aluminum wire will result in improper fit and potential connection failure.
