It includes a factory-fitted cover, a feature that protects the screw terminals from accidental shorting and debris ingress in panel or junction-box installations. The single-row layout keeps the wiring neat, and the 3-wall (tri) barrier construction between each circuit prevents flashover between adjacent terminals — a real advantage in humid environments where creepage tracking is a concern. ## 15A, 300V Rating — Sized for Branch-Circuit Power Rated 15A at 300V, this barrier strip handles branch-circuit-level power for industrial controls, lighting panels, and HVAC equipment. The 14-22 AWG wire range accepts solid or stranded conductors, and the screws with captive plate clamp down on ring or spade lugs without the plate falling off during assembly — a small detail that saves time when wiring a panel.","metaTitle":"1546833-4 Buchanan Barrier Strip, 4 Circuit, 0.375\" Pitch","metaDescription":"1546833-4 Buchanan 4-circuit barrier strip, 0.375\" (9.53mm) pitch, 15A, 300V, with cover.
