What This 2-Position Buchanan Block Does
The 2363963-2: It accepts wire from 12 AWG down to 30 AWG, making it a single-block solution for both power feeds and signal-level wiring in the same assembly. The M3 screw termination with a specified torque of 0.5 Nm (4.4 Lb-In) gives a repeatable clamp force on the conductor — overtightening strips the threads in the nylon housing, so the torque spec is a field-service parameter, not a suggestion.
Rated for 12-30 AWG, the 2363963-2 covers the common industrial wire sizes from a 12 AWG power feed to a 30 AWG signal wire in one block. The screw clamp uses a copper alloy clamp plate with nickel plating, and the screw itself is copper alloy with nickel plating — no dissimilar-metal corrosion risk at the termination point.
