Blue Sea Systems 2302 MaxiBus 250 Amp Common Bus Bar, 20-Terminal 8-32 Screw, Without Cover
Blue Sea Systems 2302 MaxiBus 250 Amp Common Bus Bar, 20-Terminal 8-32 Screw, Without Cover
The Blue Sea Systems 2302 is a 250 amp MaxiBus common bus bar built to distribute power or ground connections across a marine 12-volt or 24-volt DC electrical system from a single high-capacity source. It provides 20 individual 8-32 screw terminal positions, allowing multiple circuits to be landed on one common point instead of daisy-chaining wires or stacking ring terminals on a single stud. The bus bar uses insert-molded stainless steel studs set into an insulated base, which keeps the terminals rigid and corrosion-resistant in a marine environment while isolating the conductive path from the mounting surface. This 2302 version is supplied without a cover, so the terminals remain fully exposed for easy wire access and inspection; a covered version (2312) and an alternate uncovered variant (2303) are offered as separate part numbers in the same family if a different configuration is needed. With a centerline length of 13 inches and an overall footprint of 1 inch wide by 12 inches tall, the 2302 is sized to mount in a standard electrical panel, battery compartment, or accessory bay alongside other Blue Sea Systems components. It is a common choice for consolidating grounds, distributing accessory power, or organizing a bus system feeding multiple breakers, fuses, or electronics on a boat.
