The dual-wall barrier construction isolates adjacent terminals, and the integral mounting flange lets you bolt the block directly to a chassis or panel — no DIN rail adapter needed. ## 20 A at 300 V — Wire Gauge and Termination Each circuit accepts 12-22 AWG stranded or solid wire, terminated under a nickel-plated steel screw. The 20 A rating is per-circuit at the rated voltage, so an 18-circuit block can distribute up to 360 A total across all positions if the wiring and load are balanced — but the practical limit is the supply feed and the terminal strip's own temperature rise. The closed bottom termination means wires enter from the top only; there is no through-hole or solder tail, so this block is strictly a panel-mount power distribution point, not a PCB header. ## Chassis Mount with Flange — Installation Context The flange feature and chassis/panel mounting type tell you this block is meant to be screwed or bolted to a flat surface. The 0.374\" (9.50 mm) pitch gives enough spacing between terminals for the 20 A rating without crowding, and the dual-wall barrier reduces the chance of a screwdriver bridging adjacent terminals during wiring.","metaTitle":"1-1546306-8 Buchanan Barrier Block, 18 Circuit, 0.374\" Pitch","metaDescription":"TE Buchanan 1-1546306-8 barrier strip, 18 circuits, 0.374\" (9.50 mm) pitch, 20 A, 300 V, 12-22 AWG, UL94 V-0.
