Marinco RY504-2-30 Reverse Y Shore Power Adapter

The Marinco RY504-2-30 Reverse Y Adapter features two male plugs with special power isolation circuitry for added safety. When one plug is connected to a receptacle, the circuitry isolates the second plug. This Reverse Y provides 50A 125/250V power to your boat when only two 30A 125V receptacles are available at the dock.

On the boat side, a 50A 125/250V female connector with a sealing collar system attaches to your boat inlet or cordset. On the dock side, two locking 30A 125V male plugs attach to dockside receptacles or cordsets. Power is supplied to both circuits at the 4-wire inlet, but the dock side receptacles limit current in each circuit to 30A; the two 30A 125V receptacles must be supplied from a single power source providing between 208V and 250V for proper operation.

Note: this Reverse Y will not work with 50A, 125V, 3-wire inlets. Browse more in our shore power category.
