Blue Sea 2020 PowerBar Dual BusBar - Two 3/8"-16 Studs

The Blue Sea 2020 PowerBar Dual BusBar with two 3/8"-16 studs is the compact power distribution solution every serious boater needs in the engine room. After years running multiple battery banks and electrical systems across different vessels, you learn quickly that undersized bus bars create voltage drop, corrosion, and unreliable starting—especially when you're running high-draw accessories like thrusters, winches, and marine electronics. This dual-stud design consolidates connections into a single, organized point, eliminating the rat's nest of cables and reducing resistance at the source.

Engineered by Blue Sea Systems—the gold standard in marine electrical—this PowerBar handles 200 amps continuous and operates safely up to 48V DC, making it suitable for everything from small center console boats to larger cruising vessels. The two 3/8"-16 studs accommodate dual battery banks, distribution to main loads, or a split between starting and auxiliary systems. High-amperage busing like this is manufactured from pure copper or tinned copper to resist corrosion in the salt-spray environment; the substantial terminal studs accept industry-standard lug connectors and prevent the loosening that plague smaller setups over time.

Installers and marine electricians rely on the Blue Sea 2020 when upgrading battery distribution or rebuilding a boat's electrical backbone. Mount it in the engine compartment or battery box where wiring runs are shortest, keeping voltage loss minimal and accessibility high for maintenance or troubleshooting. The compact 3 x 3 x 6-inch footprint fits tight quarters without sacrificing amperage capacity, and the stud design integrates seamlessly with Blue Sea fuses, switches, and distribution panels for a professional, code-compliant installation that holds up for years.
