Blue Sea MaxiBus 250A BusBar Six 5/16"-18 Studs

The Blue Sea MaxiBus 250A BusBar with six 5/16"-18 studs is a professional-grade electrical distribution component designed for marine, RV, and automotive power systems where reliable multi-circuit connectivity is essential. This busbar serves as the central hub for splitting main power feeds to multiple branch circuits, eliminating the need for individual wire connections to a single point. Marine electricians, system integrators, and off-grid power specialists rely on this component to create safe, organized, and code-compliant electrical architectures.

The MaxiBus features insert-molded stainless steel studs rated for 250 amps continuous duty, eliminating the need for traditional nuts and lock washers while maintaining exceptional electrical contact integrity. Each 5/16"-18 stud accepts standard marine-grade ring terminals and accommodates heavy-gauge power cables with high torque capability for secure terminations that resist vibration and thermal cycling. The raised bus design provides clear line-of-sight access to all connection points, streamlining installation and troubleshooting while reducing the risk of crossed wires or accidental shorts.

This busbar is ideal for battery banks, alternator distribution, DC load centers, and shore power integration in vessels, campers, and expedition vehicles. Its compact footprint and six studs accommodate typical house bank splits, alternator outputs, and priority circuit feeds without requiring additional bulky junction blocks. Installation requires standard marine-grade crimped lugs sized for 5/16"-18 studs and is compatible with systems operating 12, 24, or 48 volts DC with proper conductor sizing.
