Parts Desk Insights
Best Use Case: Best for situations where you need to step between a 15A/125V dock-side straight blade and a 30A/125V locking boatside inlet, and the connection will be made in an enclosed, dry area.
Common Issues: The adapter does not include sealing collars and is not recommended for wet locations—if you plan to connect in exposed rain/spray areas, choose a sealing-collar style instead. Also confirm you’re matching the correct dock-side straight blade and boatside locking connector types before use.
