Newmar BB-5 Buss Bar

Enhance your electrical system's reliability with the robust Newmar BB-5 buss bar, engineered for high-demand DC power distribution. Whether you're wiring up a marine vessel, outfitting an RV for off-grid adventures, or building a custom solar setup, this 500-amp rated powerhouse handles heavy loads effortlessly. Its 1/4-inch thick nickel-plated copper bar ensures maximum conductivity and corrosion resistance, making it a go-to choice for professionals who demand durability in tough environments.

Key Features That Set the BB-5 Apart

• Heavy-Duty Construction: Five 5/16-inch studs spaced 1 inch apart on a solid copper bar, perfect for securing large-gauge wires with 5/16-inch ring terminals.
• Versatile Connectivity: Ideal as a central DC ground tie point or positive bus, streamlining complex wiring jobs.
• Safety First: Includes a transparent insulating cover to shield against accidental shorts while allowing easy visual inspection of connections.
• Smart Mounting Design: Keyed base for secure interlocking with compatible terminal strips, with recessed conductive parts to prevent contact with mounting surfaces. Uses standard #8 or #10 screws for easy installation.

Real-World Applications for Maximum Performance

The Newmar BB-5 shines in scenarios requiring clean, organized power distribution. In marine applications, it consolidates battery bank feeds to inverters, thrusters, and lighting circuits without voltage drops. RV enthusiasts use it to tie multiple house batteries to converters and appliances, ensuring stable power during long trips. For solar installations, it serves as a reliable combiner point for panels and charge controllers, handling surges up to 500 amps. Its compact footprint fits neatly into tight panels, while the clear cover keeps dust and moisture at bay.

Installation Tips for Flawless Setup

Getting the most from your BB-5 starts with proper prep. Torque studs to manufacturer specs—typically 75-100 in-lbs—to avoid lug slippage under vibration. Position the bar away from heat sources and ensure adequate airflow. For multi-unit setups, leverage the interlocking bases to create expandable arrays. Always disconnect power before wiring, and use heat-shrink tubing on terminals for extra protection. Pro tip: Label each connection for quick troubleshooting down the road.

Why Choose Newmar BB-5 Over Basic Alternatives?

Unlike flimsy plastic bus bars that melt under load, the BB-5's tinned copper delivers superior heat dissipation and a 500-amp continuous rating. It outperforms generic aluminum options in conductivity and longevity, reducing replacement hassles. Installers rave about the visible cover, which simplifies maintenance—no more guessing if a connection's loose. In high-stakes setups like emergency vehicles or off-road rigs, this buss bar provides peace of mind with its battle-tested design.
