Bring your boat wiring together at one accessible connection point with the BAYWATT BBK4 150A marine bus bar. Featuring six M6 terminal studs, a nickel-plated brass conductor and a clear protective cover, this DC power distribution block helps organise battery feeds or negative returns in 12–48V DC installations.

Choose a red or black insulated base to identify the role of each bus bar in your electrical system. The six studs provide separate attachment points on one common conductor, helping reduce cable stacking at battery terminals and making individual connections easier to access during installation, inspection and maintenance.

Key Features

Red or Black Bus Bar for Positive and Negative Connections

Both colours have the same electrical rating and six-stud layout. Use a separate bus bar for each polarity: all six studs on an individual BBK4 are electrically connected.

Cleaner Boat Wiring, Easier Maintenance

Frequently Asked Questions

Is the 150A rating per stud or for the whole bus bar?

The 150A rating applies to the complete bus bar, not to each stud. The total current carried by the bar must remain within this rating.

Are the six terminals independent circuits?

No. All six M6 studs are joined by the same brass conductor. The BBK4 creates a common positive or negative connection point; it does not provide six electrically isolated terminals.

Does this marine bus bar include fuses?

The BBK4 is a connection and distribution component, with no built-in fuses or circuit breakers. Select cable sizes and external circuit protection to suit the connected loads and the installation.
