If an RV's detachable shore-power cord has a damaged connector, missing retaining ring or worn cover, it is important to identify the cord end, inlet and locking system separately. Marinco's 30A 305CRV and 50A 6364CRV families are different. The 103RV and 103ELRV accessories also use different retaining-ring designs. Compare exact part numbers and catalog photographs before ordering.
Identify the connector at the RV, not just the pedestal plug
A detachable shore-power cord may have one connector for the power pedestal and a separate female connector at the RV inlet. Matching a shore-power component requires the correct nominal electrical rating, connector face, retaining hardware and cable details.

Marinco 305CRV: 30A female cord-end connectors
The 305CRV is a yellow/white female cord-end connector for a compatible 30A RV inlet. The 305CRV.VPK is its separately packaged retail version. Before ordering either, compare the label and contact orientation on the original cord end rather than treating every 30A locking connector as a universal fit.
103RV vs 103ELRV: protective covers and locking rings
Marinco 103RV is a 30A vinyl connector cover with a threaded locking ring. 103ELRV uses the Easy Lock retaining-ring arrangement. Both are catalogued for the 305CRV family, but ring engagement depends on the mating inlet. These accessories help retain and shield a compatible connection; they are not a cure for damaged contacts or overheated terminals.
Marinco 6364CRV: a separate 50A cord-end family
Marinco 6364CRV and retail-packed 6364CRV.VPK are 50A female cord-end connectors. Their mating arrangement differs from the 305CRV 30A family. The connector's rating alone does not guarantee it fits a 50A inlet of another make or another locking design.
Replacement inlets, conversion kits and full cords
Marinco 301ELRV is a white covered 125V-class power inlet; 303SSEL-BRV uses a stainless-steel housing. The correct replacement depends on the original inlet's amperage, inlet pins, housing size, mounting opening and weather cover.
Marinco 30ARVKIT is a 30A hardwired-cord-to-detachable conversion kit with an electrical box, connector and cover. It is not a simple plug replacement. Changing the shore inlet or converting a hardwired cord requires qualified electrical installation.
A complete cord may be preferable when a conductor, sheath or molded connection is damaged. Select the length and shore/inlet ends of 30SPP.RV or 6152SPPRV2 by their exact specification, rather than length alone.
