Terminal blocks provide four independent 30A circuits for organizing marine, RV, and automotive electrical connections while keeping wiring separated and easier to manage.

The Blue Sea Systems 2504 uses a closed-back design that insulates the powered terminals from the mounting surface. Each screw pair forms one isolated circuit, making it suitable for distributing separate electrical connections. Optional jumpers can combine circuits when a common connection is needed.

  • Four 30A circuits: Supports organized power distribution across four independent terminal paths.
  • Closed-back construction: Insulates the powered terminal area from the mounting surface.
  • Isolated screw pairs: Keeps each circuit electrically separate for cleaner wiring layouts.
  • Jumper-compatible design: Allows selected circuits to be combined into common circuits.
  • Nickel-plated brass bus material: Provides a conductive connection surface suited to marine and vehicle electrical applications.

Use the 2504 as a compact terminal block for marine electrical systems, RV wiring, automotive accessories, and other low-voltage power-distribution projects. The four-circuit layout helps separate connections within a panel or wiring system, while the closed back reduces the chance of the powered terminal area contacting the mounting surface.

Each screw pair operates as an isolated circuit, allowing individual loads or wiring runs to remain separated. When a shared connection is required, compatible jumpers can link selected circuits. Its 30A continuous rating and 600V AC/DC maximum voltage rating support a broad range of electrical connection tasks; select wiring, overcurrent protection, and installation practices appropriate to the specific application.
