The dual-wall barrier (2 Wall) between each terminal physically isolates adjacent circuits, reducing the chance of a short from a stray strand or tool slip during wiring. This is a chassis/panel-mount block with a flange for bolting to a cabinet wall or sub-panel. The top termination uses screws; the bottom is closed, meaning all wire entry and clamping happens from above — no pass-through studs below the block. ## Wiring and Termination — What the Screws and Wire Range Mean The 1546670-6 accepts 14-22 AWG wire. That covers the common power and control wire sizes in industrial panels — 14 AWG for branch circuits up to the 25 A rating, 16-18 AWG for control wiring, 20-22 AWG for signal or sensor leads. No crimp tool, no insertion force to manage — just a screwdriver. The 12 wire entries (2 rows of 6) mean each circuit has two positions, typically used for daisy-chaining or looping power through the block.","metaTitle":"TE Connectivity 1546670-6 Buchanan Barrier Strip, 6 Circuit","metaDescription":"TE Connectivity 1546670-6 Buchanan barrier strip, 6 circuits, 0.437\" pitch, 25A, 300V, screws top termination, UL94 V-0.
