Blue Sea 8386 AC Rotary Switch Panel 30 Ampere 2 Positon + OFF, 4 Pole

The Blue Sea 8386 AC Rotary Switch Panel 30 Ampere 2 Position + OFF, 4 Pole is a marine-grade electrical control solution designed for vessels requiring reliable shore power management. Built by Blue Sea Systems—an industry leader in marine electrical components—this rotary switch panel handles the demands of modern boating by seamlessly switching between multiple AC power sources. Whether you're operating a cruiser with dual generators, managing shore power inputs at the dock, or running a larger cabin cruiser with complex electrical loads, this four-pole configuration delivers the switching capacity serious boaters depend on when safety and reliability matter most.

This panel operates at 120 volts with a robust 30-ampere rating, providing the electrical throughput needed to power multiple 120-volt AC load groups simultaneously without risk of overload or nuisance trips. The two-position rotary design with an OFF detent allows you to switch between a 120-volt AC shore power source and a 240-volt AC source while distributing power to two independent 120-volt load groups—a configuration that eliminates the guesswork of manual bus-bar management and reduces the likelihood of inadvertent double-feed conditions. The four-pole construction ensures that neutral and ground paths are properly isolated and controlled during every transition, meeting ABYC and USCG electrical standards for marine installations.

This rotary switch is ideal for owners of larger cruising sailboats, trawlers, and motor yachts that rely on shore power connectivity or multi-source AC generation. Installation typically integrates with a main AC panel or electrical distribution center, and the compact footprint (7 × 5 × 9 inches) fits neatly into most marine electrical enclosures. If you operate a vessel with two independent AC systems, generator backup capability, or require the flexibility to isolate loads during dockside power transitions, the Blue Sea 8386 delivers the control and safety margins that extend equipment life and protect your crew.
