The Buchanan 6DBL-03-006 is a 3-circuit barrier strip from the #6 series, built for panel wiring where a ring lug under a screw is the right termination. The 0.375" (9.53mm) barrier spacing gives you room for 12 AWG wire with a ring tongue without crowding the adjacent terminal — that spacing also keeps the creepage path long enough for the 300V rating in a damp cabinet. Rated 25A per circuit, this block handles motor starter feeds, control transformer secondaries, or distribution points inside an industrial enclosure. The three-wall (tri) barriers between each position prevent tracking across the surface if dust or moisture gets in — a real concern in a pump house or washdown area.
Accepts 12-22 AWG; a ring lug is the secure choice, but a spade tongue works too. The steel screws have a zinc clear chromate finish that resists corrosion in the field.
