Blue Sea 1990 PowerBar 1000 with 8 x 3/8" terminal studs

The performance of a busbar can be increased by attaching the primary feed wire to the center of the busbar. The performance can be further increased by first attaching the primary feed wire followed by the highest load wire to the same terminal. This will allow the current to be carried by the large cables and avoid sending all of the current through the busbar. Although this will improve the performance of the busbar, it does not change the actual ampacity rating of the busbar and should not be used when comparing one busbar to another.
