The dual-wall barrier (2 Wall) physically separates each circuit, which prevents accidental bridging between terminals when wiring in a panel or enclosure. Rated 20A per circuit at 150V, it handles power-level loads typical of industrial control cabinets, power distribution boards, and HVAC equipment. ## Wire Termination and Gauge Range This is a field-service-friendly detail: the technician can loosen the screw, insert the stripped wire, and retighten without fishing for a loose washer. The wire range is 12-22 AWG, which covers the common power and control wiring sizes found in panel builds.","metaTitle":"4DB-P108-03 Barrier Strip, 3 Circuits, 0.325\" Pitch, 20A","metaDescription":"Buchanan 4DB-P108-03 barrier block, 3 circuits, 0.325\" (8.26mm) pitch, 20A, 12-22 AWG, UL94 V-0.
