Supporting mix of any class copper and/or aluminum conductor without concern for expansion, contraction, and galvanic corrosion, NIMBUS® 2X has built-in wire stop feature that lets installer use flex or code conductor on either side without needing to stagger inputs and outputs. This optimizes space by halving dimensional requirements. Screw design promotes vibration resistance, compresses conductor without damage, and eliminates need for ferrules, rendering this part reusable.
