Blue Sea Systems Battery Terminal Mount Busbar — 100A 32VDC
Mount directly to your battery terminal and distribute power to multiple circuits cleanly and safely with this Blue Sea Systems battery terminal mount busbar. Constructed from tin-plated copper, it handles up to 100 amps at 32VDC — making it well-suited for both 12V and 24V marine electrical systems. The #8-32 screw terminals with captive star lock washers ensure a secure, vibration-resistant connection at each circuit tap.
This busbar eliminates the need for wire-to-wire connections at the battery terminal, giving you a professional, serviceable distribution point that mounts directly to the battery post. It's a clean, compact solution for boats where space is limited and wiring organization matters.

Parts Desk Insights
The battery terminal mount busbar is the right choice when you need to tap multiple circuits directly from a battery post without running everything through a panel. It's most commonly used on the negative side — giving you a clean, central ground point for accessories, bilge pumps, and electronics that all need a solid negative return. On the positive side, pair it with an inline fuse for each branch circuit, or step up to the ST-Blade Battery Terminal Mount Fuse Block if you want individual fuse protection built in. The captive star washers are a genuine advantage in a marine environment — they stay in place during installation and resist loosening from vibration, which is one of the most common causes of intermittent electrical faults on boats.
