This 50-pack of WAGO 221 Series compact splicing connectors provides a tool-free solution for connecting solid, stranded, and fine-stranded electrical copper conductors ranging from 24 to 12 AWG. Featuring a 3-conductor port configuration, these lever-actuated connectors are up to 40 percent smaller than older styles to maximize junction box space. The clear, transparent polycarbonate housing allows easy visual inspection for correct strip lengths and proper wire insertion depth, while orange operating levers offer quick open-and-close functionality. Built with integrated test ports for simple voltage checking without conductor removal, these reuseable components support up to 600 volts and 20 amps in residential, commercial, or industrial lighting installations
