Blue Sea Systems Traditional Metal AC Main Circuit Breaker Panel, 120V AC, White Toggle, Metered

Overview

The Blue Sea Systems Traditional Metal AC Main Breaker Panel is a metered 120V AC distribution panel for boats that need a dedicated AC main with branch circuit protection in a traditional metal layout. It is built around white-toggle A-Series circuit breakers and is offered in 8-position and 11-position configurations, with either a Micro Voltmeter + Micro Ammeter package or a Digital Multi-Function Meter with Alarm.

This panel family is made for AC shore-power and onboard AC distribution work where clear circuit status, reverse-polarity indication, and organized wiring matter. The hot, neutral, and safety ground buses are installed and pre-wired, which helps keep the back of the panel cleaner during a refit or new electrical build.

The range includes compact 5.25 in x 11.25 in panels for tighter vertical spaces and wider 10.50 in x 7.50 in panels for larger AC loads and more branch circuits. Each configuration uses 120V AC labeling and circuit indication, so owners can quickly see which AC circuits are on from the cabin, electrical locker, or nav station.

Key features

• 120V AC main breaker panel range for marine AC distribution, shore-power circuits, and onboard AC loads.
• Available with 8 or 11 branch positions, matching different vessel layouts and available panel space.
• Red reverse-polarity indicating LED helps identify an unsafe AC polarity condition before loads are used.
• Hot, neutral, and safety ground buses are installed and pre-wired for a cleaner panel installation.
• Backlit circuit label positions and ON indicator LEDs make circuit status easier to read in low light.
• White-toggle A-Series circuit breakers provide a familiar switch feel and a consistent panel appearance.
• Metered configurations support AC monitoring through either separate micro voltage and amperage meters or a digital multi-function meter with alarm.
• Traditional metal construction suits refits, panel extensions, and full AC panel replacements on cruising and fishing boats.

Variants

This product is offered in four metered configurations. The main differences are the number of branch positions, the panel size, and the meter package fitted to the panel.

The 8-position versions share the 5.25 in x 11.25 in panel size, while the 11-position versions share the 10.50 in x 7.50 in panel size. Meter packages vary between separate micro voltage and amperage meters and a digital multi-function meter with alarm.

• 8074: 8 positions, 5.25 in x 11.25 in panel, Micro Voltmeter + Micro Ammeter package. This layout suits a narrower panel opening while keeping voltage and amperage visible on separate meters.
• 8406: 8 positions, 5.25 in x 11.25 in panel, Digital Multi-Function Meter with Alarm package. This version keeps the same narrow panel size and uses one digital meter package for consolidated AC monitoring.
• 8076: 11 positions, 10.50 in x 7.50 in panel, Micro Voltmeter + Micro Ammeter package. The wider panel format gives more branch circuit capacity while retaining separate voltage and amperage readings.
• 8407: 11 positions, 10.50 in x 7.50 in panel, Digital Multi-Function Meter with Alarm package. This configuration pairs the larger branch circuit layout with a digital meter package for boats that need more AC circuit positions.

Installation and setup

These panels are intended for 120V AC marine electrical systems. Before installation, confirm the vessel voltage, shore-power inlet arrangement, breaker requirements, panel cutout, and available depth behind the mounting surface.

The pre-wired bus layout helps reduce wiring work inside the electrical locker, but AC systems still require careful installation. A qualified marine electrician should verify the neutral and safety ground arrangement, breaker sizing, reverse-polarity indication, and final circuit labeling before the system is placed in service.

Compatibility and fit

The 5.25 in x 11.25 in versions are a practical fit where vertical space is available but panel width is limited. The 10.50 in x 7.50 in versions work better where the boat needs more branch circuits and has a wider mounting area.

This panel range is a good match for boat owners replacing an older AC panel, expanding an existing AC distribution setup, or cleaning up shore-power and branch circuit control in a cabin, galley, nav station, or protected electrical compartment.

Materials and marine use

The traditional metal panel format is well suited to the vibration, access limitations, and service needs found on boats. The white toggle breakers, backlit labels, and circuit status LEDs make the panel easier to operate during evening dockside use, generator operation, or checks before getting underway.

For saltwater boats, the panel should be mounted in a protected interior location where it is shielded from spray and direct weather exposure. Keep the rear wiring space dry, ventilated, and accessible so future circuit checks and breaker service can be handled without disturbing nearby equipment.
