About this product

The Blue Sea Systems MaxiBus 250A BusBar is a heavy-duty electrical distribution busbar for consolidating multiple conductors or feeding multiple circuits in marine AC and DC systems. It is rated for 250A continuous current, with a maximum voltage of 300V AC or 48V DC, making it a practical fit for battery banks, main distribution points, inverter feeds, charging systems, and negative return consolidation on boats.

The raised tin-plated copper bus gives installers room to land multiple wires cleanly, while the UL 94-V0 rated glass-reinforced thermoplastic base helps handle heat in demanding electrical compartments. Recessed mounting holes help reduce the chance of accidental shorts when the busbar is mounted near aluminum or steel surfaces.

Key Features

• 50A continuous rating for high-current distribution and return circuits on board.
• Maximum voltage rating of 300V AC and 48V DC for marine electrical systems within those limits.
• Tin-plated copper CDA 110 / UNS 11000 bus material for low-resistance current transfer.
• UL 94-V0 rated glass-reinforced thermoplastic base for heat resistance in electrical compartments.
• Insert-molded stainless steel studs allow high stud torque without a separate securing nut.
• Raised bus layout gives better access when terminating multiple conductors on one stud or screw point.
• Recessed mounting holes help prevent accidental shorts to metal mounting surfaces.
