The 0.375\" (9.53 mm) pitch gives each terminal enough physical spacing to handle the 25 A rating without excessive heat buildup between adjacent circuits, making this a power distribution block rather than a signal-level terminal. The three-wall barrier design isolates each position from its neighbors, reducing the chance of a stray strand bridging two circuits during wiring. Wire acceptance from 12 AWG down to 22 AWG covers both the heavy feed conductors and the smaller branch-circuit wiring typical in panel builds. The steel, stainless terminal screws hold up under repeated torquing without galling the threads. ## Board Layout and Wiring Fit The 0.375\" pitch means the ten PC pins on 9.53 mm centers define the board footprint. The through-hole mounting requires drilled and plated holes matching the pin diameter, with enough keep-out between rows to clear the screw terminals above the board. On the wiring side, the screw-clamp top termination accepts solid or stranded wire in the 12-22 AWG range. The three-wall barrier reduces the risk of a stripped conductor touching an adjacent terminal, which is a real concern when multiple wires share a common trough in a panel.","metaTitle":"TE Connectivity 3-1437653-8 Buchanan Barrier Block","metaDescription":"TE Connectivity 3-1437653-8 Buchanan #6 barrier strip, 10 circuits, 0.375\" pitch, 25 A, 300 V, 12-22 AWG, UL94 V-0.
