Blue Sea Systems Traditional Metal AC Rotary Switch Panel, Source Selector, Reverse Polarity and Power LEDs

Overview

The Blue Sea Systems AC Rotary Switch Panel is an AC source selector for boats that need a clear way to transfer between shore power, generator power, or other onboard AC inputs. It is built around a rotary switch layout with an OFF position, so the AC source feeding the vessel can be selected at the panel rather than managed through loose cords or improvised switching.

This traditional metal panel range covers 120V AC, 230V AC, and 240V AC systems, with 30A and 65A versions available across 2-pole, 3-pole, and 4-pole configurations. The panels are intended for installations where AC circuit protection is handled elsewhere in the system, making them a practical fit for main AC distribution arrangements that already have the required breakers and protection devices.

The panel face uses heavy 1/8 inch aluminum 5052 alloy with a two-part polyurethane slate gray finish. Red reverse-polarity indicators and green power-available indicators help the operator confirm source status before energizing onboard loads.

Key features

• Source selector panel for connecting one of two or three AC sources to one circuit, depending on the selected configuration.
• Available in 120V AC, 230V AC, and 240V AC versions for different vessel AC systems.
• 30A and 65A ratings support common small-boat and larger AC service requirements.
• 2-pole, 3-pole, and 4-pole options allow the panel to match the vessel wiring layout and source arrangement.
• Rotary switch operation includes an OFF position for clear source isolation at the panel.
• Red reverse-polarity LEDs and green power-available LEDs give useful status information at the AC panel.
• Heavy 1/8 inch aluminum 5052 alloy panel face with a two-part polyurethane slate gray finish suits exposed marine electrical panels.
• Compact source selection format works well when circuit protection is already provided elsewhere in the AC distribution system.

Variants

This AC Rotary Switch Panel range is offered in multiple electrical configurations. The main differences are nominal voltage, maximum amperage, pole count, and source input count, so the correct version depends on the vessel AC system and how many incoming sources need to be managed.

The range includes 120V AC, 230V AC, and 240V AC models, with 30A and 65A ratings. Two-source and three-source input layouts are available, along with 2-pole, 3-pole, and 4-pole switching arrangements for different AC wiring schemes.

Installation and setup

This panel belongs in an AC distribution system where the switching plan is clear and the necessary circuit protection is installed separately. It is commonly used near the main AC panel on boats that alternate between dockside shore power, onboard generator power, or other AC inputs.

Before installation, the selected variant should match the vessel voltage, amperage, pole count, and number of source inputs. AC shore power and generator wiring should be installed and tested by a qualified marine electrician, especially where reverse polarity indication, grounding, neutral handling, and transfer switching are involved.

Use on board

This panel is a good match for cruising boats, sportfishing boats, and larger sailboats that need a dedicated AC source selector rather than a breaker panel with integrated source switching. The rotary layout keeps operation simple at the dock, at anchor with a generator running, or during service work when the AC source needs to be isolated.

The indicator lights are especially useful in marinas and mixed shore power environments, where confirming available power and checking for reverse polarity at the panel can prevent avoidable AC system problems before loads are turned on.

Shipping

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

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.
