Daiertek 12V Marine Bus Bar with Six M8 Studs, 400A Copper Power Distribution Block for Marine Use

Daiertek 400A 12V Marine Bus Bar With Six M8 Terminal Studs Copper Power Distribution Block is a heavy‑duty solution designed to keep high‑current marine, automotive, and solar wiring organized, safe, and reliable. This 12V bus bar supports up to 400A continuous current and handles up to 300V AC or 48V DC, making it ideal for boats, cars, and off‑grid systems where robust power distribution matters.

Crafted from a tinned thickened copper plate, it offers high conductivity and excellent corrosion resistance to extend the life of the block in harsh environments. The unique fixing method between the marine bus bar and its base resists torque, keeping the copper bar securely attached even in vibration. A protective cover shields exposed areas to prevent accidental short circuits, while the exposed sides enable multi‑angle installations to fit a variety of wiring layouts. The red and black color coding clearly marks positive and negative connections for quick, safe servicing.

Equipped with six M8 (5/16") terminal studs, this 12V power distribution block helps you keep wiring neat and accessible, reducing clutter and the risk of shorts. The integrated nut and washer design ensures tight, reliable contact between lugs and copper bar, delivering dependable performance in demanding maritime and automotive applications.
