Marinco Y503-2-30 EEL (2)-30A-125V Female to (1)50A-125V Male - "Y" Adapter - Yellow

The Marinco Y503-2-30 EEL "Y" adapter is purpose-built for boaters and anglers who need reliable power distribution at the dock. This dual-inlet marine power adapter allows you to connect two 30-amp shore power sources to a single 50-amp boat inlet, solving the common problem of limited dock receptacles or split power requirements on modern vessels. Whether you're docked at a marina with only 30-amp pedestals available or managing dual-circuit power systems, this Y adapter ensures you maintain full electrical capacity without sacrificing convenience or safety.

Built with marine-grade construction, the Marinco Y503-2-30 features locking connectors on both 30-amp female inlets paired with integrated sealing collar systems that keep moisture and corrosion out in wet dock environments. The single 50-amp male plug on the boat side delivers combined power from both shore connections, while the sealed collar design prevents water ingress at connection points—critical protection when your boat is exposed to spray, rain, and humidity. The bright yellow color coding meets standard marine electrical visibility requirements, making it easy to identify correct connections during setup or maintenance.

This adapter is ideal for cruisers, fishing boats, and live-aboards that regularly shore-power or operate in marinas with mixed electrical infrastructure. Installation is straightforward: female ends connect to dock-side 30-amp pedestals or cordsets, while the male connector attaches directly to your boat's inlet or existing 50-amp cordset. The sealed design ensures years of reliable performance in salt spray and freshwater environments, making it essential equipment for any boater managing variable dock-power situations or upgrading older electrical systems.
