Blue Sea Systems 360 AC Circuit Breaker Panel, 30A ELCI, 5 Branch Positions, 120V AC, M2 AC Multimeter, Flat Rocker

Overview

The Blue Sea Systems 1504 is a 120V AC distribution panel with a 30A ELCI main breaker, five 15A branch breaker positions, and an M2 AC multimeter. It gives you one place to switch and protect incoming shore power, then split that feed across five onboard AC circuits.

This layout works well on boats that need a compact AC panel instead of a larger multi-source board. The main ELCI trips at 30mA leakage current, the breakers use flat rocker actuators, and the panel needs 3.99 in of depth behind the mounting surface.

Key features

• 120V AC panel with one 30A ELCI main and five 15A branch circuits
• 30mA leakage trip at the main to shut down power when leakage faults are detected
• Integrated M2 AC multimeter for at-a-glance AC system monitoring at the panel
• Flat rocker breaker actuators with green ON indicating LEDs for quick status checks
• Backlit label positions that stay readable in low light
• Uses two Blue Sea Systems 1331 insulating panel backs when rear protection is needed, sold separately

Compatibility and fit

This panel is built for 120V AC systems. It is not a DC breaker panel and it is not a multi-source transfer panel. The configuration is fixed around a single 30A AC main and five 15A branches, so it fits installations where that branch count and circuit rating already match the boat’s wiring plan.

Check the space behind the mounting surface before cutting the opening, especially in tight helm consoles, cabin bulkheads, and electrical lockers. The 3.99 in depth matters once cable bends and terminal clearance are added.

Use on board

This is a good match for boats with a 120V shore inlet and a limited number of AC loads that need separate branch protection. It suits refits and new installs where the owner wants ELCI protection, branch control, and panel-mounted AC monitoring in one assembly.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
