Marinco RY504230 Installation Instructions

Marinco RY504230 Technical Bulletins


Reverse "Y" Adapter

The Reverse "Y" Adapter has 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. The reverse "Y" provides 50A 125/250V power when only two 30A 125V receptacles are available.
Note: Reverse "Y" will NOT work with 50A, 125V, 3-wire inlets. Power is provided in both circuits to the 4-wire inlet, but the dock side receptacles limit the current in each circuit to 30A. The two 30A 125V receptacles must be supplied from a single power source providing from 208V to 250V between them for proper operation.

  • 50A 125/250V

  • Attaches to boat inlet or cordset


Dock Side: Male Plug

WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.



The adapter can safely use a 50-amp airborne power system and a 50-A shore power cord in a docking station that can only provide 30-amp power. There are two reverse "Y" adapters...
