The 0.325\" (8.26mm) pitch spaces the terminals wide enough for screwdriver access and for routing 12-22 AWG wire without crowding. The dual-wall barrier (two walls per terminal) isolates each circuit from its neighbour, reducing the chance of a stray strand bridging between positions. Rated 20A per circuit at 150V, it handles power distribution in control cabinets, HVAC panels, and industrial equipment — not just signal-level wiring. ## Wiring it — screw termination and wire range Top termination is screws with captive plates — the plate stays under the screw head, so you don't fish for a loose washer when wiring in a tight panel. Wire range is 12-22 AWG, which covers most field wiring from a 12 AWG power feed down to a 22 AWG thermostat or sensor lead. The bottom termination is a PC pin that solders into the board — the pin diameter and length are standard for the 0.325\" pitch pattern, so the footprint matches the Buchanan 4DB PCB layout.","metaTitle":"TE 1-1546462-2 4DB Barrier Strip, 12 Circuits, 20A, 150V","metaDescription":"TE Connectivity 1-1546462-2 barrier strip, 12 circuits, 0.325\" pitch, 20A, 150V, 12-22 AWG, right-angle PC pins.
