Blue Sea 2102 PowerPost Plus Cable Connector - 5/16" Stud

The Blue Sea 2102 PowerPost Plus Cable Connector with 5/16" stud is a compact electrical distribution solution engineered for marine, automotive, and industrial applications where space constraints limit traditional bus bar installation. This connector allows technicians and system integrators to consolidate multiple smaller gauge wires onto a single high-amperage connection point, eliminating the need for bulky distribution blocks in tight engine compartments, battery boxes, and control panel installations.

Built by Blue Sea Systems—a trusted leader in electrical power distribution—the PowerPost Plus features a 150-ampere bus rated for high-current applications while accommodating smaller diameter wires. The 5/16" stud configuration provides a standardized connection interface compatible with ring terminals and lug connectors commonly found in 12/24-volt DC systems. Its compact design (6 × 2 × 7 inches) minimizes footprint without sacrificing load capacity, making it ideal for retrofit installations and new build-outs where real estate is premium. The connector's construction supports reliable connections under vibration and thermal cycling typical in marine and mobile applications.

Marine electricians, RV system designers, and automotive technicians benefit most from this connector when upgrading battery banks, charging systems, or auxiliary power distribution networks. Installation is straightforward: simply affix the stud to a solid mounting surface, then terminate multiple 4–8 AWG wires (or smaller) to the bus using appropriately sized ring terminals. It pairs seamlessly with battery isolators, inverters, and auxiliary disconnect switches in 12V/24V applications. For those seeking a compact alternative to oversized bus bars or multiple terminal blocks, the PowerPost Plus delivers efficiency, reliability, and durability in a space-saving package.
