Y-adapters let you split one shore power outlet between two power cords. (You're still limited to the rated amperage of the outlet.) All Y-adapters are locking and equipped with covers and sealing collars. Waterproof for use in wet locations.
Most shore power systems are based on 30A service unless the additional capacity of 50A service is available for larger boats. We recommend that you use a 30A shore power cord and inlet on your boat for consistency, and then obtain waterproof adapters for other amperages.
