Blue Sea Systems Terminal Block, 65 A, 4-Gang (2604)
This Blue Sea Systems terminal block provides four circuits on one block, rated 65 A. Each screw pair is one isolated circuit, and jumpers allow the creation of common circuits where needed. The closed-back design completely insulates power from the mounting surface, keeping the connections isolated from the surface they are mounted to.

Parts Desk Insights
- Best use case: Organizing high-current DC wiring on a boat's panel, where several circuits need to share one terminal block and the closed-back insulation suits a metal mounting surface.
- Most common customer mistake: Exceeding the 65 A rating on the block. Add up the continuous loads on the circuits it serves before ordering.
- Sizing and fitment guidance: Confirm the number of circuits suits the 4-gang layout and match the terminal block's 65 A rating to the circuit, and use jumpers if common circuits are needed rather than isolated ones.
