Collection: Busbars

Power distribution on a boat gets complicated fast, and a busbar keeps it organized by giving multiple circuits a single common connection point. Blue Sea Systems and BEP Marine cover the range here, from compact battery terminal mount bars to Maxibus and PowerBar 1000 units for heavier loads. The PowerBar 1000 comes in 8 and 12 position versions with either 5/16 inch or 3/8 inch terminal studs, so matching the bar to your existing cable lugs is straightforward. Maxibus bars combine studs and screw terminals on one bar, useful when connecting wires of different gauges.

Before buying, count your circuits and confirm which stud or lug size your cables use. Covered versions, like the Maxibus units that pair with snap-on covers sold separately, block moisture and prevent accidental shorts. Battery terminal mount bars suit installs where you want to expand connections directly at the battery rather than routing back to a panel. If you need both a positive and negative common bus, plan mounting room for two bars. All products here are genuine, authorized dealer stock carrying full manufacturer warranty.
