    Any lug,either compression or mechanical is fine, just needs to be rated for aluminum wire. A compression lug for #4/0 will require a hand or hydraulic crimping tool with the specific die to fit the crimp lug.

    A mechanical lug only needs nuts ,bolts, and lock washers, and a allen wrench.

    Be sure to treat the bare stripped wire with wire brush, applying anti-oxidant compound, and properly torque the connection.
