Blue Sea Systems AC Main + 3 Positions Circuit Breaker Panel, 120V AC, 30A Main, Digital Multimeter

Overview

The Blue Sea Systems 8405 is a 120V AC main distribution panel with one 30A double-pole main breaker, three 15A single-pole branch breakers, and an 8247 digital multi-function meter with alarm. The face size is 7.50 x 5.25 inches, which makes it a practical fit for compact AC sections on cruisers, sailboats, and refit projects where panel space is limited.

It works as a full replacement panel or as an extension to an existing 120V AC system. Hot, neutral, and safety ground buses are installed and pre-wired, and the front panel adds a reverse-polarity warning LED, backlit circuit label positions, and ON indication LEDs at each breaker position. The digital meter lets you check AC voltage, current, power, and frequency from the panel, with high and low voltage alarms plus a high current alarm.

Key features

• 120V AC panel layout with one 30A double-pole main breaker and three 15A single-pole branch breakers
• 8247 digital meter displays AC voltage, current, power, and frequency, with high and low voltage alarms plus a high current alarm
• Reverse-polarity indicator gives a clear warning when shore power wiring is not correct
• Hot, neutral, and safety ground buses are already installed and pre-wired
• Backlit label positions and ON LEDs make circuit status easier to read in low light
• Includes a 30-label basic AC panel label set for cleaner circuit identification

Installation and setup

This panel suits boats that need a straightforward 120V AC main with space for up to three 15A branch circuits. The breaker layout is well matched to common cabin and utility loads when the rest of the boat's AC design, wire size, and shore-power protection are set up correctly. Countersunk mounting holes help the panel sit cleanly in a finished electrical face.

For refits, it helps to confirm the front cutout, wire routing, and service clearance behind the mounting surface before ordering. An optional 4027 isolation cover is available for the rear of the panel and measures 5-1/4 x 7-1/2 x 3 inches.

Compatibility and fit

The 8405 is built for 120V AC installations, so it is intended for boats using North American style shore power rather than 230V AC systems. It is a good match for owners replacing an older AC panel or adding a compact sub-panel where breaker control, meter feedback, and clear circuit labeling need to stay in one small footprint.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
