Blue Sea Systems Traditional Metal AC Main Source Selector Panel, Lockout Slide, Reverse Polarity LED

Overview

The Blue Sea Systems Traditional Metal AC Main Source Selector Panel is an AC distribution panel family for boats that need safe selection between two AC power sources and branch circuit control from one organized panel.

These panels are available for 120V AC and 230V AC systems, with configurations for 2 sources plus either 4 or 9 branch positions. Depending on the variant, the panel is arranged in a horizontal or vertical format, and selected models include an AC voltmeter for quick source voltage checks at the panel.

Each panel uses double-pole AC main circuit breakers with an installed lockout slide, helping prevent both AC sources from being connected at the same time. Hot, neutral, and safety ground buses are installed and pre-wired, which makes the panel a practical choice for refits, panel upgrades, or replacing an older AC distribution layout.

Key features

• AC source selector layout for two onboard AC sources, commonly used for shore power and generator or inverter-fed AC systems.
• Lockout slide between the main breakers helps prevent simultaneous connection of both AC sources.
• Available in 120V AC and 230V AC configurations to match the vessel electrical system.
• Branch circuit options include 4-position and 9-position layouts for smaller or more expanded AC panels.
• Horizontal and vertical formats support different helm, cabin, or electrical panel spaces.
• Red reverse-polarity indicating LED gives a clear warning when AC input polarity needs attention.
• Backlit circuit label positions and ON indicating LEDs make circuit status easier to read in low-light cabins and electrical compartments.
• Hot, neutral, and safety ground buses are installed and pre-wired to reduce panel wiring work during installation.
• Traditional metal panel construction suits full replacements and extensions to existing Blue Sea Systems style AC panels.

Variants

This panel range varies by nominal voltage, number of branch circuit positions, panel orientation, and meter configuration. The 120V AC variants are built around 30A double-pole main breakers and 15A single-pole branch breakers, while the 230V AC variants use 16A double-pole main breakers and 8A single-pole branch breakers.

The 9-position versions give more room for AC loads such as outlets, battery chargers, water heaters, and onboard appliances. The 4-position versions keep the panel smaller for boats with fewer AC circuits or limited mounting space. Horizontal models suit wider panel openings, while vertical models fit narrower spaces where height is available.

Installation and setup

Before installation, match the panel voltage to the vessel AC system and confirm that the source arrangement, breaker ratings, and number of branch circuits suit the boat’s wiring plan. AC panels should be installed where the main source breakers are easy to reach and where the reverse-polarity and ON indicators are visible during normal operation.

The pre-wired bus structure helps simplify the job, but final wiring still needs correct conductor sizing, overcurrent protection, grounding, strain relief, and source labeling. AC shore power and onboard AC distribution work should follow applicable marine electrical standards and be completed by a qualified marine electrician when required.

Compatibility and fit

The available formats cover 120V AC and 230V AC boats with two selectable AC sources. The range includes panels for 2 sources plus 9 positions in both horizontal and vertical layouts, along with smaller 2 sources plus 4 positions layouts for more compact installations.

For refit work, check the panel cutout, overall panel dimensions, depth behind the mounting surface, and the direction of wire entry before ordering. These panels are often used when replacing an older AC panel or extending an existing traditional metal panel layout while keeping the circuit controls grouped in a familiar toggle-breaker format.

Use cases on board

This panel family is a good match for cruising boats, sportfishing boats, and sailboats that need to switch safely between two AC sources while keeping branch circuits clearly separated. It is especially useful where the owner wants a physical lockout at the source selector, visible circuit status, and a panel style that fits a traditional marine electrical layout.

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.
