Blue Sea 2104 PowerBar 600AMP Cable Connector 4 x 3/8 16 Stud Terminal

The Blue Sea 2104 PowerBar 600AMP Cable Connector 4 x 3/8 16 Stud Terminal is the backbone of reliable marine electrical distribution, designed for serious boaters and anglers who demand bulletproof power management. After years on the water, any experienced captain knows that electrical failures don't happen at the dock—they happen mid-run when you're far from help. This heavy-duty power bar consolidates multiple battery and auxiliary power connections into a single, robust junction point, eliminating the need for tangled wire clusters and reducing the risk of corrosion-related voltage drops that can cripple fish finders, GPS, and engine start systems.

Built to withstand 600 amperes of continuous current, this PowerBar features four 3/8-inch 16-stud terminals that accept large-gauge marine-grade cables without compromise. The 300V AC and 48V DC rating covers virtually all recreational and light-commercial marine applications, from dual-battery trolling motor setups to integrated engine and accessory networks. The compact 8 x 3 x 9-inch footprint fits neatly in engine compartments or battery boxes, while the solid stud design eliminates mechanical stress points that plague cheaper connectors. Its industrial construction handles salt spray, vibration, and the thermal cycling that kills lesser components within a single season.

This connector excels in high-draw scenarios: running a 36-volt trolling motor plus 12-volt fish finder, sounder, and navigation gear simultaneously without voltage sag or heat buildup. Anglers retrofitting older boats or upgrading to modern lithium battery systems will appreciate the modular terminal layout, which accommodates factory batteries, auxiliary packs, and aftermarket chargers on the same bar. Professional installers specify the Blue Sea 2104 when reliability matters; weekend warriors benefit from the same military-grade durability. Pair it with appropriately sized marine cable and a quality breaker for a power distribution hub that will outlast the boat.
