It uses a dual-wall (2 Wall) barrier design with screw top termination and a closed bottom — the wire enters from the top and terminates against the screw, with no through-hole or solder tail underneath. This is a chassis- or panel-mount terminal block, built for power distribution in industrial control panels, HVAC equipment, and similar 300V-class wiring junctions where a field-serviceable screw connection is preferred over a pluggable connector. The 20A per-circuit rating at 300V puts this strip in the power-distribution class, not signal-level. Each screw terminal can carry the full rated current continuously, but the limiting factor in a multi-circuit block is the total temperature rise inside the enclosure — if you load all six circuits near 20A, the heat builds across the thermoplastic body. The 12-22 AWG wire range accepts standard building wire; the nickel-plated steel screws resist corrosion in humid environments. ## Wiring and installation This is a screw-clamp barrier block — strip the wire to the appropriate length, insert it into the wire entry (12 entries for 6 circuits, dual-row), and tighten the nickel-plated steel screw. The closed bottom means there's no solder tail or PCB footprint to worry about; it mounts directly to the chassis or panel via the flanges. The dual-wall barrier provides physical separation between adjacent terminals, reducing the chance of accidental shorting during wiring or maintenance. The 0.374\" (9.50mm) pitch gives enough space for a standard screwdriver and ring-tongue or spade terminals.","metaTitle":"TE Connectivity 1546306-6 Buchanan Barrier Strip, 6 Circuit","metaDescription":"TE Connectivity 1546306-6 Buchanan barrier strip, 6 circuits, 0.374\" pitch, 20A, 300V, UL94 V-0.
