Parts Desk Insights
Best suited for mid-size powerboats and sailboats running 6 or fewer circuits from a single distribution point. If your build requires more circuits, consider the Sierra FS46630 12-Gang Dual Bus Bar or the Blue Sea Systems 100A Battery Terminal Mount Busbar for battery-level distribution. Pair with properly rated ring terminals and tinned marine-grade wire for a code-compliant, corrosion-resistant installation.
