Bluewater 4-Stud 600A Heavy-Duty Marine Bus Bar

The Bluewater heavy-duty four-stud bus bar is designed for large cable connections in battery, inverter, and other high-load electrical systems. Its four main studs give installers a solid common point for conductors that would be difficult to manage on smaller terminal blocks. The assembly is intended for marine, RV, and industrial environments where vibration and moisture make improvised distribution connections a poor choice. It provides a cleaner and more serviceable way to organize heavy conductors while helping minimize connection resistance.

The main terminals use 3/8-16 stainless-steel studs for secure high-load cable attachment. Mounting holes measure 0.21 in and are spaced 5.26 in apart, with #10, 1/4 in mounting hardware specified for installation. Corrosion-resistant hardware supports long-term service around moisture and salt exposure. The rigid body also helps keep large cable lugs aligned so connection pressure is concentrated at the intended contact surfaces.

• Four heavy-duty stud positions
• 3/8-16 stainless-steel terminal studs
• 5.26 in mounting-hole spacing
• Suitable for battery and inverter distribution points

Install the block where heavy cables can be supported without placing leverage on the studs. Use properly crimped lugs, protective covers, and upstream overcurrent devices as required by the connected system. For additional high-current distribution components, browse Bus Bars & Power Distribution.
