Blue Sea MaxiBus 250A BusBar Two 5/16"-18 Studs and Twelve #10-24 Screws

The Blue Sea MaxiBus 250A BusBar is a heavy-duty electrical distribution component engineered for marine, RV, automotive, and industrial applications requiring reliable high-amperage power management. This bus bar serves as a central junction point where multiple power sources and loads connect simultaneously, eliminating the need for multiple individual connections and reducing installation complexity. Rated for 250 amps continuous, it is ideal for systems with demanding electrical loads where space efficiency and robust contact integrity are critical operational requirements.

This MaxiBus features two insert-molded stainless steel 5/16"-18 studs that eliminate the need for securing nuts while permitting high torque application for superior electrical contact and reliability. The twelve #10-24 screws provide additional terminal points for auxiliary circuits and branch connections. The raised bus design ensures unobstructed access to all terminal points, simplifying troubleshooting, maintenance, and future circuit additions without disturbing existing connections. Stainless steel construction resists corrosion in salt-air and moisture-rich environments, extending service life and maintaining consistent conductivity over years of operation.

This bus bar is essential for experienced installers upgrading or building complex electrical systems in vessels, mobile equipment, and off-grid installations where code compliance and fault tolerance demand professional-grade distribution architecture. The dual stud configuration accommodates large-gauge primary power cables, while the threaded screw terminals support branch circuits and auxiliary loads. Proper installation requires torquing studs and screws to manufacturer specifications using appropriate crimped lug terminals rated for 250 amps. This component integrates seamlessly with Blue Sea Systems fuse blocks, switches, and monitoring devices for complete system protection.
