Robust Power Distribution for Demanding Applications
Engineered for high-stakes electrical setups, the Newmar BB-2/8 buss bar stands out as a powerhouse solution for consolidating DC power connections. Whether you're wiring up a marine battery bank, an RV inverter system, or a solar array in an off-grid van, this heavy-duty component handles up to 500 amps with ease. Its 1/4-inch thick nickel-plated copper bar ensures maximum conductivity and corrosion resistance, keeping your power flow steady even in harsh environments like salty sea air or dusty trails.
Key Design Highlights
- Versatile Connection Points: Two 5/16-inch studs spaced 1-inch apart pair perfectly with large-gauge ring terminals, while eight #8 screws offer flexibility for smaller wires—ideal for mixed setups.
- Safety First: A crystal-clear insulating cover snaps on to shield against accidental shorts, letting you visually confirm all connections without disassembly.
- Smart Mounting: Keyed base design allows seamless interlocking with compatible terminal strips. Recessed studs keep live parts away from surfaces, using simple #8 or #10 screws for secure installs.
- Built to Last: Premium nickel plating on copper fights oxidation, delivering reliable performance over years of vibration and exposure.
Perfect Fit for Marine, RV, and Mobile Power Systems
Boat owners love it for tying multiple battery feeds into a single DC ground or positive bus without voltage drops. RV enthusiasts rely on its compact footprint for clean inverter and alternator hookups. In custom truck or van builds, it simplifies solar charge controller distributions. The 6 1/16" x 1 1/2" base fits tight panels, maximizing space while supporting serious current loads—think 400+ amp hours from lithium banks.
Real-World Advantages
- Eliminates messy wiring spaghetti by centralizing connections.
- Reduces heat buildup with superior copper conductivity.
- Supports upgrades: Scale from basic setups to high-draw accessories like winches or air conditioning.
- Peace of mind: Exceeds typical demands, preventing failures during peak usage.
Newmar Buss Bar Model Comparison
Choose the right size for your project. The BB-2/8 balances studs and screws for hybrid needs, but the full lineup offers options for every scale.
| Model | Qty. of 5/16" Studs | Base Size |
|---|---|---|
| BB-2 | 2 | 3 1/16" x 1 1/2" |
| BB-2/8 | 2 plus 8 - #8 screws | 6 1/16" x 1 1/2" |
| BB-5 | 5 | 6 1/16" x 1 1/2" |
| BB-8 | 8 | 9 1/16" x 1 1/2" |
Effortless Installation for Pros and DIYers
Prep your ring terminals with 5/16-inch holes for studs and match #8 screws to smaller lugs. Torque to manufacturer specs—around 75 in-lbs for studs—to avoid stripping. Snap the cover on post-wiring. Mount horizontally or vertically; the interlocking base shines in multi-unit arrays. Pro tip: Use heat-shrink tubing on all connections for extra moisture protection in wet environments.
Frequently Asked Questions
What is the amp rating of the Newmar BB-2/8 buss bar?

What's the difference between BB-2/8 and other models?
The BB-2/8 uniquely combines 2 studs and 8 screws on a 6-inch base, bridging simple stud-only (like BB-2) and all-stud (like BB-5) designs.
Is this buss bar suitable for 12V, 24V, or 48V systems?
Yes, its voltage-agnostic design works across low-voltage DC systems, focusing on current handling up to 500A.
- Ideal as a DC ground tie point or positive bus, these heavy duty, 500 amp rated bus bar assemblies feature 5/16" studs on 1" centers in 1/4" thick copper bar for common connection/distribution of large wire gauges and accommodate 5/16" ring terminals.
- One combination model features two 5/16" studs and eight #8 screws, accommodating multiple size wire terminals.
- All bus material is nickel-plated copper.
- A clear insulating protective cover is provided to prevent short circuits and provide visibility of lugs.
- The mounting bases are keyed for interlocking and may be mated with the terminal strips (described above). Conductive parts are captured and recessed away from the mounting surface. Use #8 or #10 screws for mounting.
