The 0.437\" (11.10 mm) pitch gives enough clearance between terminals to land 14 AWG stranded wire under the screw clamp without crowding. Dual-wall barriers between circuits reduce the chance of a stray strand bridging to the adjacent terminal during termination — a practical safeguard when the panel is wired under time pressure. ## What the 25 A / 300 V Rating Means for the Panel The 25 A per-circuit rating is sized for distributing branch-circuit power inside the cabinet. At 300 V, it covers common industrial control voltages with margin. This block mounts to a chassis or panel via the integral flange — it is not a DIN-rail part, so plan for two screw holes in the panel layout. The top termination uses steel screws with a nickel finish; the bottom is closed, meaning the block terminates the wire on the top side only and the circuit continues through an internal bus bar to the adjacent position. The 2-circuit, 4-wire-entry configuration (two wires per circuit) allows daisy-chaining a feed-through and a tap on the same terminal.","metaTitle":"TE Connectivity 1546670-2 Buchanan Barrier Strip, 2 Circuit","metaDescription":"TE Connectivity 1546670-2 Buchanan barrier strip, 2 circuits, 0.437\" pitch, 25A, 300V, 14-22 AWG, UL94 V-0.
