Bluewater 12-Terminal 250A Marine Bus Bar

The Bluewater 12-terminal marine bus bar provides a central connection point for distributing power to multiple heavy-load or accessory circuits. It can be used on boats, RVs, and off-grid systems where a clean common connection is preferable to stacking numerous conductors on a single battery post. The twelve-terminal layout helps keep branch wiring organized and makes it easier to trace individual connections during service. The block can support either positive or negative distribution when installed with the proper circuit design and protection.

Stainless-steel terminal hardware is used at the connection points for durability in a demanding environment. The mounting pattern uses 0.21 in holes with #10, 1/4 in fasteners, and the mounting holes are spaced 8.5 in apart. Those dimensions give installers clear planning information before drilling the mounting surface. The rigid assembly is designed to tolerate vibration, moisture, and salt exposure better than improvised open connection stacks.

• Twelve connection terminals for organized distribution
• 1/4 in stainless-steel studs
• 8.5 in mounting-hole spacing
• Suitable for positive or negative distribution layouts

Mount the bus bar on a secure, non-conductive surface with enough room for cable bends and terminal covers or protection used elsewhere in the system. Each branch still requires conductor sizing and circuit protection appropriate to the connected load.
