Marinco, 50 Amp Shorepower, Reverse Y Adaptor, 2 Male Plugs
Provides a boat with 50A 125/250V power from two 30A/125V locking receptacles. Separate mechanical relays that will not permit power to energize second plug, offering protection from the exposed blades. Female with sealing collar. 5 year warranty.
The Reverse "Y" Adapter (RY504-2-30) has two male plugs with special power isolation circuitry for added safety. When one plug is connected to areceptacle, the circuitry isolates the second plug. The reverse "Y" provides 50A 125/250V power when only 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 dockside receptacleslimit the current in each circuit to 30A. The two 30A 125V receptacles must be supplied from a single power source providing from 208V to 250Vbetween them for proper operation.
