It accepts 14-22 AWG wire on both rows, with 20 wire entries total (two per circuit), so you can daisy-chain a feed-through without a separate jumper. Mounts to a chassis or panel via the integral flange — the flange provides a mechanical anchor so the screw-termination torque doesn't twist the block off the panel. Top termination is screw-type with a steel screw and nickel finish; bottom termination is closed, meaning the screw clamps down on the wire from above with no through-hole access underneath. This is a common configuration for a barrier strip that sits against a metal panel — the closed bottom keeps the screw from bottoming out into the panel surface.","metaTitle":"TE Connectivity 1-1546670-0 Buchanan Barrier Block","metaDescription":"TE Connectivity 1-1546670-0 Buchanan barrier strip, 10 circuits, 0.437\" pitch, rated 25A at 300V.
