Parts Desk Insights
Best Use Case: Use when your dockside power is configured for 50A (125/250V) locking, but your boat inlet or cordset uses a 30A (125V) locking configuration—so you can safely make the dock-to-boat connection with a sealed, marine-grade pigtail.
Common Issues: Most common problems come from selecting the wrong amperage/voltage/locking style for the dock and boat connectors—always confirm the dockside receptacle and the boat-side inlet/cable are the locking type and match the adapter’s stated dock (50A 125/250V) and boat (30A 125V) ratings. For wet-location connections, ensure mating surfaces are clean and that any sealing collar interface is properly seated before use.
