The 1986775-8: It accepts 12 AWG solid or stranded wire through a screwless push-button clamp — no screwdriver needed for termination, which speeds assembly in high-volume builds.
Sizing the Connection: Current, Voltage, and Wire Gauge
The 12 AWG wire capacity means this block handles the full 15 A without exceeding the temperature rise limits of the polyamide housing — 12 AWG is the practical ceiling for that current in a terminal block. The tin-plated copper alloy contacts are suited for the typical mating cycle count in a fixed installation; if frequent re-termination is expected, the screwless clamp still holds up well since there's no screw thread to wear.
Termination and Installation
Wire termination is screwless — a push-button releases the clamp, the stripped wire inserts, and releasing the button grips the conductor. No special tool is needed beyond a wire stripper.
