Blue Sea 2300 Common 150A BusBar – 10 Gang with Cover: Clean DC Power Distribution for Marine, RV & Off-Grid Systems
The Blue Sea 2300 Common 150A BusBar – 10 Gang with Cover is a compact, marine-grade bus bar designed for clean, safe DC power distribution in 12V and 24V systems. Whether you’re wiring a boat, RV, van conversion, off-grid cabin, or emergency vehicle, this component helps you replace messy, stacked battery lugs with a professional-grade distribution point.
Built by Blue Sea Systems, the 2300 bus bar is engineered for harsh environments, high current, and long-term reliability. It’s a natural fit alongside other Blue Sea bus bar and Blue Sea fuse block products in a complete DC system.
Key Features of the Blue Sea 2300 Common 150A BusBar
1. 150A Continuous Current Rating
The 2300 bus bar is rated for 150 amps continuous, making it well-suited for mid-size DC systems that power:
- 12V or 24V refrigerators and freezers
- Lighting circuits
- Water pumps and fans
- Navigation and communication electronics
- Moderate-size inverters and chargers
In real-world applications—marine, RV, or mobile—the 150A rating gives you headroom for surge loads and combined draws from multiple circuits.
2. 10-Gang Design for Clean, Organized Wiring
Instead of stacking six or seven ring terminals on a single battery post, the 10-gang design gives each circuit its own dedicated connection point. That means:
- Cleaner wiring layouts
- Easier circuit identification
- Fewer loose or stressed connections
- Reduced risk of overheating at a single terminal
For anyone who has had to troubleshoot a messy battery compartment, the 10-gang layout is a big upgrade.
3. Protective Snap-On Cover
The included snap-on insulating cover is critical for safety and reliability, especially in tight spaces. It helps:
- Prevent accidental contact with tools or metal objects
- Reduce the risk of short circuits
- Provide a cleaner, more finished look
- Protect terminals from incidental splashes or debris
In boats, vans, and RVs—where components live in cramped lockers or under seats—the cover is not just a bonus; it’s essential.
4. Marine-Grade Build Quality from Blue Sea Systems
Like the rest of the lineup from Blue Sea Systems, the 2300 bus bar is built for demanding environments:
- Tin-plated copper for excellent conductivity
- Stainless steel hardware for corrosion resistance
- High-strength insulating base for durability
- Vibration-resistant design for mobile and marine use
This is the same design philosophy that makes every Blue Sea bus bar and Blue Sea fuse block a favorite among installers and boatyards.
Why Use a Bus Bar Instead of Stacking Lugs?
A bus bar like the Blue Sea 2300 doesn’t just make things look nicer—it solves real electrical problems:
- Reduced voltage drop: Better contact surfaces and fewer shared studs mean more stable voltage.
- Improved safety: No overloaded battery posts, fewer chances of loose or overheated connections.
- Easier upgrades: Adding a new circuit is as simple as adding a ring terminal to an open position.
- Simplified troubleshooting: Circuits are spaced out and easier to trace.
When you combine a bus bar with a properly sized Blue Sea fuse block, you get both clean distribution and correct overcurrent protection for each circuit.
Ideal Applications for the Blue Sea 2300 150A BusBar
Marine Vessels
On boats, the 2300 works perfectly as a central positive or negative distribution point near the house battery bank, DC panel, or inverter. The marine-grade construction from Blue Sea Systems is specifically designed for saltwater and vibration.
RVs and Travel Trailers
In RV applications, this bus bar is a great fit for:
- Splitting power to interior lights, fans, slides, and pumps
- Consolidating grounds in a central location
- Feeding sub-panels or DC fuse blocks
Paired with a Blue Sea fuse block, it offers a very clean upgrade over factory wiring.
Van Conversions & Overland Rigs
For van builds and overland trucks, the 2300 is ideal when you’re running:
- Fridge/freezers
- Roof fans and lights
- USB and 12V outlets
- Diesel heaters
- Auxiliary gear and radios
Using a quality Blue Sea bus bar in your build helps avoid many of the electrical headaches that come from cheap distribution hardware.
Off-Grid Cabins
In small off-grid systems, the 2300 can act as the main DC distribution point between your batteries, charge controller, inverter, and DC loads—especially when paired with other Blue Sea Systems components.
How the 2300 BusBar Fits into a Complete Blue Sea System
A typical clean DC installation might look like this:
- Battery bank with main fuse or breaker
- Positive Blue Sea bus bar for distribution
- Negative bus bar for returns
- One or more Blue Sea fuse block units to protect branch circuits
- Inverter/charger, solar charge controller, DC/DC charger, and DC loads connected in an organized layout
Because all of these parts are designed by Blue Sea Systems, they work together smoothly and give your wiring a unified, professional feel.
Installation Overview
Installation is straightforward for anyone familiar with basic DC wiring:
- Mount the bus bar on a solid surface near your battery bank, distribution panel, or power center.
- Connect the main feed from your battery or upstream fuse/breaker to the common stud.
- Terminate branch circuits with the appropriate ring terminals and connect them to the 10 gang terminals.
- Torque fasteners properly to ensure secure, vibration-resistant connections.
- Snap on the cover to protect the terminals once everything is tested and verified.
For systems with multiple branch circuits, consider routing each one through a Blue Sea fuse block to match wire size and load protection correctly.
Why Choose Blue Sea Systems for Distribution Hardware?
Installers and DIY builders choose Blue Sea Systems because their components are:
- Designed for marine and mobile environments
- Built with high-quality metals and plastics
- Rated conservatively and tested in real-world conditions
- Well-supported with clear documentation and standardized designs
Using a Blue Sea bus bar and Blue Sea fuse block together—with the 2300 bus bar as a core component—creates a cleaner, safer, and more reliable electrical system.
Conclusion
The Blue Sea 2300 Common 150A BusBar – 10 Gang with Cover is a compact, rugged, and highly practical solution for DC power distribution in marine, RV, van, and off-grid systems. Its 150A continuous rating, 10-gang layout, protective cover, and marine-grade construction make it a trusted choice for anyone serious about system reliability and safety.
If you’re building or upgrading a DC system and want clean wiring, easier troubleshooting, and long-term dependability, pairing this bus bar with other Blue Sea Systems components—like a compatible Blue Sea fuse block or additional Blue Sea bus bar units—is a smart move.
