The 221 10 AWG series connects solid, stranded and fine-stranded wires with the simplicity of lifting and pushing a lever. No tools are required. It is designed to combine different wire sizes (20 to 10 AWG) and types, while quickly installing devices with higher levels of power consumption. This product is suitable for small-spaced applications that need more functions integrated into them. The series offers the ability to perform testing from two different sides, even after installation.
