Newmar BB2 Bus Bar

The Newmar BB2 Bus Bar is a heavy-duty electrical distribution component engineered for RV, marine, and automotive electrical systems requiring reliable DC power management. Designed as either a DC ground tie point or positive bus, this assembly provides a centralized connection hub for multiple large-gauge wire runs. Whether you're upgrading an RV power system, installing auxiliary batteries, or managing a complex marine electrical network, the Newmar BB2 delivers the solid construction and current capacity necessary to handle demanding applications safely.

Built from 1/4" thick copper bar stock, the Newmar BB2 features five 5/16" studs spaced at 1" centers to accommodate 5/16" ring terminals on common wire gauges and larger. The 500-amp rating reflects this assembly's capacity to safely distribute substantial electrical loads across multiple connection points without voltage drop or heat degradation. Copper's superior conductivity ensures efficient current transfer, while the rigid stud configuration maintains consistent electrical contact under vibration and thermal cycling—critical factors in mobile applications where reliability cannot be compromised.

RV system integrators, marine electricians, and automotive customizers rely on the Newmar BB2 to consolidate ground or positive distribution in battery banks, inverter installations, and auxiliary power systems. The combination mounting design (noted in the original specification) permits flexible installation orientation to match panel layouts or enclosure constraints. At just 1 lb, this assembly adds minimal weight while eliminating the need for multiple terminal blocks, reducing connection points and improving system reliability in harsh mobile environments.
