Blue Sea Systems 2105 250 Amp MaxiBus Common BusBar, 12 x #10-24 Terminal Screws, No Cover

The Blue Sea Systems 2105 is a 250 amp MaxiBus common BusBar designed to distribute AC or DC power across multiple circuits from a single, high-capacity connection point. It is built with a tin-plated pure electrical copper conductor for maximum conductivity and corrosion resistance, mounted on a UL 94-V0 rated base material that resists high heat. The BusBar is rated for a continuous load of 250A AC/DC with a maximum voltage of 300V AC / 48V DC, making it suitable for demanding marine electrical panels and distribution systems.

The 2105 provides 12 x #10-24 terminal screws for connecting individual circuit wires, plus 2 x 5/16"-18 terminal studs for the main power feed connections, giving it 12 circuits of distribution capacity from one BusBar. Two mounting holes accept #10 (M5) screws for secure panel installation. This BusBar is sold without a cover, so an optional cover should be sourced separately if circuit protection or accidental-contact shielding is required. It is part of Blue Sea Systems' MaxiBus common BusBar lineup used to simplify wiring, reduce voltage drop, and organize multiple circuits in boat electrical systems.
