Marinco RY504-2-30 Y-Adapter, 50A 125/250V to Two 30A 125V, Marine Shore Power

The Marinco RY504-2-30 is a marine-grade Y-adapter that lets a boat with a single 50 amp 125/250 volt shore power inlet connect to two separate 30 amp 125 volt shore power cords instead. This gives boaters flexibility when tying up at a marina, RV park, or storage facility that only offers 30 amp service, or when using two 30 amp cords to feed a single 50 amp shore power system. The adapter is built with marine-grade construction to stand up to dockside and marine environments, and it provides circuit isolation between its connections.

The adapter is finished in yellow for high visibility on the dock and features two outlets on its 30 amp male end paired with a single 50 amp 125/250 volt female connection. It measures 12.8 x 12.2 x 4.6 inches and weighs 7.9 pounds, giving it a solid, durable build for regular dockside use.
