Sea-Dog Dual Bus Bar with Cover – 12 Terminals (4266933)
This dual bus bar from Sea-Dog provides a clean, organized solution for distributing DC or AC power across multiple circuits on your boat. Each of the two independent bus bars can handle its own circuit — use one for DC positive and one for DC negative distribution, or configure them for AC neutral and safety ground on a single block. A clear polycarbonate cover protects all connections from accidental contact and corrosion.
Constructed from tin-plated copper with an ABS housing, the bus bar resists corrosion in marine environments. Each bus includes two 1/4"-20 stainless steel stud terminals for main feed connections and six #8-32 stainless steel screw terminals for branch circuits — 12 terminals total across both buses. Mounting hardware (four #8 flat-head fasteners) is included.

Parts Desk Insights
Best use case: This dual bus bar is ideal for boats where you want to keep positive and negative DC distribution — or AC neutral and ground — neatly organized in a single footprint. The 12-terminal layout handles most mid-size electrical panels without needing a second block, and the polycarbonate cover is a practical safety feature in any enclosed electrical compartment. It's a solid choice for rewires, panel upgrades, or new builds where a tidy, code-compliant distribution point matters.
If you need fewer terminals, the Sea-Dog Buss Bar with Cover – 4 Terminals (4266913) and Sea-Dog Buss Bar with Cover – 6 Terminals (4266923) are available for smaller installations.
