Each of the 28 wire entries (two per circuit, arranged in two rows) accepts 14-22 AWG wire, and the dual-wall barrier construction physically separates adjacent terminals to prevent accidental bridging. ## 25 A at 300 V — Power Handling for Distribution Duty The 25 A per-circuit rating at 300 V means this block carries branch-circuit current for motors, heaters, or lighting contactor panels, not just signal-level loads. The 0.437\" pitch provides enough creepage between adjacent circuits to sustain that voltage rating without flashover in a typical 40°C ambient inside an enclosure. The nickel-plated steel terminal screws resist corrosion in the field, and the closed bottom termination keeps live conductors from being exposed on the underside of the block — a safety consideration when the block is mounted to a grounded metal panel.","metaTitle":"1-1546670-4 Buchanan Barrier Block, 14 Circuit, 0.437\" Pitch","metaDescription":"TE Connectivity Buchanan 1-1546670-4 barrier strip, 14 circuits at 0.437\" pitch, rated 25 A at 300 V.
