I used the Blue Sea 2300 covered bus bar in my electrical build. Its row of ten screw terminals is a different connection format from the larger stud bars elsewhere in my system.
I used the Blue Sea 2300 shown by model number in my original electrical drawings. It belongs to the distribution-and-return hardware in the house electrical system.
The combination of smaller screw connections and larger end studs is the defining layout detail. My kit also includes the four-stud PowerBar and an eight-stud covered bar, so keeping the exact names with the drawings helps distinguish their roles.
My build context
My system diagram places this component among the storage and distribution equipment. The named bar provides a common return connection in that drawing, separate from the switches, breakers and the SmartShunt.
The physical roof work also produced groups of device wires and a shared entry route into the van. That is part of the build context shown in my photographs: routing the leads and organizing their eventual connections were related stages with different hardware.
The storage detail from my electrical-system diagram, including component E20.
My main comparison point is the connection row. Ten screw positions can organize a different group of leads from a bar built primarily around large studs. The two end studs are additional connection features, rather than two more small screw positions.
The model suffix matters here. Blue Sea sells a 2301 without the cover; my drawing names the covered 2300. That is an easy distinction to lose when product listings use the same common-bus-bar family name.
Keep the covered 2300 and uncovered 2301 separate in the component list.
Alternative products
Two alternatives to compare
The Blue Sea 2301 keeps the ten-screw common-bar format but omits the cover supplied with the 2300. The covered four-post set changes to larger stud connections and comes as a red/black pair. Compare terminal style and enclosure arrangement as separate choices.
This pair of covered bus bars provides four threaded connection posts on each bar. The posts have 5/16-inch stud threads for ring-terminal connections.
