TECH TIP The Marinco® Shore Power Adapters give you more power hook-up flexibility and resolve a variety of dock side power center / boat side inlet power incompatibility problems. Types of Adapters “Y” Adapters* let you split one dock side receptacle between two boat inlets of similar or dissimilar power configurations. “Y” adapters are fully molded and equipped with Marinco’s unique sealing collar and covers (where indicated) for use in wet locations. The Reverse “Y” Adapter (Part # RY504-2-30) The reverse “Y” provides 50A 125/250V power when only two 30A 125V receptacles are available. *Available with standard locking rings or with the new EEL quick locking system Straight Adapters are high-quality, one-piece adapters similar in usage to Pigtail Adapters. However, they do not have sealing collars and are not recommended for use in wet locations. Use only in an enclosed, dry location, such as powering your boat from a 15A power receptacle inside your house.
