Marinco 50-Amp Locking Shore Power Connector

The Marinco 6364CRN Locking Shore Power Connector is a 50A female cord end for 125/250V systems, in a 4-wire configuration.

This is the female cord end, the part that plugs into the boat's inlet, sold for repairs and custom cordsets rather than as a complete cable. A shore power cord usually fails at one end rather than along its length, so replacing the connector saves the cost of a whole 25 or 50-foot cordset.

The four-wire configuration with three blade openings matches standard 50A 125/250V service. It mates with a compatible inlet or plug rather than mounting as a fixed receptacle, which is the distinction from the dockside parts in this range.

Corrosion-resistant materials handle repeated dockside exposure while maintaining a secure connection. It should be fitted using correctly sized marine-grade cable and proper wiring practice, and Marinco backs it with a five-year warranty. Explore more shore power connectors.
