The 0.437\" (11.10mm) pitch gives enough physical spacing to handle 14-22 AWG wire terminated under nickel-plated steel screws, with a closed bottom that prevents accidental contact with the board or panel underneath. ## 25A Per Circuit — Sized for Power, Not Signal The 25A per-circuit rating means each position carries bus-level current for feeding contactors, motor starters, or terminal strips downstream. This is not a signal-level terminal block; the 14-22 AWG wire range and the dual-wall barrier construction (2 Wall (Dual)) are designed to prevent flashover between adjacent circuits at the rated 300V. The screw termination with nickel-plated steel screws provides a gas-tight connection on stranded wire when torqued to the manufacturer's specification. ## Mounting and Wire Entry This block mounts to a chassis or panel via the integral flange (Features: Flange). The 14 wire entries (7 circuits × 2 rows) accept one wire per position. The closed bottom means no through-hole solder tails — wiring is entirely above the mounting surface, which simplifies panel layout and keeps the back side of the panel clear for other components.","metaTitle":"1546670-7 Buchanan Barrier Strip, 7 Circuits, 25A, 300V","metaDescription":"1546670-7 Buchanan barrier strip, 7 circuits, 0.437\" pitch, 25A, 300V, UL94 V-0.
