Blue Sea Systems 2315 MiniBus 100 Amp Common BusBar with Cover, 4 x #10-32 Studs

The Blue Sea Systems 2315 MiniBus is a 100 amp common distribution busbar built for consolidating DC positive or negative connections, or AC grounding conductors, on a boat's electrical panel. It provides one 8 AWG to 4 AWG input terminal feeding four 16 AWG to 10 AWG load terminals, all on #10-32 studs, making it a compact way to split a single power or ground feed out to multiple circuits without daisy-chaining wires. The bus itself is tin-plated copper C11000 for low-resistance, corrosion-resistant conductivity, mounted on a reinforced polycarbonate base with a clear polycarbonate cover included to guard against accidental contact with live studs. Mounting holes accept 1/4 inch (6 mm) screws for a secure panel or bulkhead installation. Rated for 100A AC and 100A DC continuous, with a maximum operating voltage of 300V AC or 48V DC, the 2315 suits both DC battery/ground distribution and AC grounding conductor consolidation in marine electrical systems. Screw terminals should be torqued to 15 in-lb (1.69 Nm) for a reliable, low-resistance connection. Its compact MiniBus footprint makes it a practical fit for helm panels, battery compartments, and distribution panels where space is limited but multiple circuits need to share a common connection point.

Frequently Asked Questions

What is the Blue Sea Systems 2315 used for? The 2315 MiniBus is a common distribution busbar for consolidating DC positive or negative wiring, or AC grounding conductors, at a single point rather than daisy-chaining connections between terminals.

How many terminals does the 2315 busbar have? It has one 8 AWG to 4 AWG input terminal and four 16 AWG to 10 AWG load terminals, all on #10-32 studs.

What is the amperage rating of the Blue Sea 2315? 100 amps continuous, rated for both AC and DC use, with a maximum operating voltage of 300V AC or 48V DC.

Does the 2315 come with a cover? Yes, the Blue Sea Systems 2315 includes a clear polycarbonate cover to protect against accidental contact with the live terminal studs.

What wire sizes fit the 2315 MiniBus? The single input terminal accepts 8 AWG to 4 AWG wire, and each of the four load terminals accepts 16 AWG to 10 AWG wire.

What material is the bus made of? The current-carrying bus on the 2315 is tin-plated copper C11000, chosen for conductivity and corrosion resistance in a marine environment.

How is the 2315 busbar mounted? Its mounting holes accept 1/4 inch (6 mm) screws for securing the busbar to a panel or bulkhead.

How much torque should be applied to the terminal screws? Blue Sea specifies a screw terminal torque of 15 in-lb (1.69 Nm) for the 2315's #10-32 stud terminals.

How much does the Blue Sea 2315 weigh? The 2315 MiniBus busbar weighs 0.18 pounds.

Can the 2315 be used for AC grounding conductors as well as DC? Yes, the 2315 MiniBus is rated for both DC distribution (positive or negative) and for collecting AC grounding conductors.

What is the base of the 2315 busbar made from? The busbar base is reinforced polycarbonate, with a clear polycarbonate cover included over the terminal studs.
