Blue Sea 2301 150AMP Common BusBar 10 x #8-32 Screw Terminal

The Blue Sea 2301 150AMP Common BusBar 10 x #8-32 Screw Terminal is a marine-grade electrical distribution component designed for vessels, RVs, and off-grid power systems requiring reliable multi-point circuit connections. This busbar serves as a central hub for consolidating positive or negative bus connections, eliminating the need for multiple individual terminals and reducing installation complexity in electrical cabinets and panel applications. Engineered for demanding marine environments, it provides the robust infrastructure necessary for systems managing high amperage loads safely and efficiently.

Built by Blue Sea Systems—a trusted manufacturer of marine electrical products—this busbar features ten #8-32 screw terminals that accept standard marine-grade wire gauges, with stud design geometry that ensures direct terminal-to-bus contact for minimal resistance at connection points. The stainless steel studs and fasteners resist corrosion in saltwater and humid conditions, while the rigid construction withstands high torque values necessary for secure electrical bonds without loosening over time. The 150-amp rating accommodates substantial power distribution in multi-circuit installations, making it suitable for battery banks, alternator feeds, and main distribution applications in both DC and auxiliary AC systems.

Marine electricians, RV technicians, and battery system integrators benefit most from this compact, modular busbar when designing reliable power distribution schemes in tight spaces where traditional wiring harnesses create clutter and potential failure points. Installation requires only a screwdriver and basic electrical knowledge; wires terminate directly into the stainless steel studs using standard ring or spade lugs rated for #8-32 hardware. Its 3×3×8-inch footprint fits easily into existing panel cavities, and the 150-amp capacity pairs well with Blue Sea fuses, breakers, and battery switches as part of a comprehensive onboard electrical system.
