Blue Sea 2312, 150 Ampere Common Busbar 20 x 8-32 Screw Terminal with Cover

The Blue Sea 2312 150 Ampere Common Busbar with 20 x 8-32 Screw Terminal and Cover is a heavy-duty electrical distribution hub engineered for demanding marine, industrial, and tactical vehicle installations where reliable power distribution under high amperage load is non-negotiable. This busbar consolidates multiple power circuits through a single, low-resistance connection point, eliminating the need for stacked battery terminals or unreliable inline fuses.

The stud-design terminal configuration provides direct stud-to-bus contact, minimizing resistance at the critical connection interface—essential when every millivolt drop translates to voltage sag under full load. Stainless steel studs and fasteners accept high-torque terminal connections without corrosion or thread stripping, while the tin-plated copper bus maintains maximum conductivity and resists oxidation in salt air and high-moisture environments. The UL 94-VO rated base material is self-extinguishing and resists deformation under sustained heat, a critical safety feature in engine compartments and confined electrical cabinets where thermal buildup is inevitable.

This busbar serves operators who require centralized power distribution for auxiliary systems—LED lighting arrays, communications equipment, hydraulic winches, or aftermarket electronics—on tactical vehicles, expedition rigs, and patrol boats. Twenty terminal positions accommodate the complexity of modern vehicle electrical architecture without requiring multiple distribution points. The included cover protects against accidental shorts, tool drops, and environmental contamination during system assembly and troubleshooting.

Common busbar systems are the standard solution in military motor pools, emergency services fleets, and marine applications where code compliance and reliability are mandated. The 150-amp rating accommodates typical auxiliary loads without the heat and failure modes associated with undersized distribution terminals.
