Before choosing a replacement RV power cord, decide whether you need a new male pedestal plug, a female cord connector, a locking vehicle-end connector, or the complete cord. RV cords with similar amperage ratings may terminate in different ways. This parts-reference guide compares practical examples from AP Products, Valterra and Marinco and explains why 30A extension, detachable and hardwired cords are not interchangeable.
Three cord configurations that solve different problems
Extension cord
Valterra A10-3025E
Detachable RV cord
Valterra A10-3025ED
Hardwired RV cord
Valterra A10-3025END
30A male and female replacement cord ends
AP Products 16-00580 and 16-00581 are separate male and female 30A plug ends. Valterra A10-P30VP is a 30A male plug with a grip handle, while A10-R30VP is its separately catalogued female connector. Select using the full original pattern and the cord manufacturer's requirements, not the black housing or handle alone.




50A replacement cord ends
AP Products 16-00578 and 16-00579 are separate male and female 50A cord-end records. Valterra A10-P50VP and A10-R50VP are likewise male and female replacement parts. A 50A plug or receptacle must match the four-wire supply arrangement and its listed mating configuration; do not assume it is interchangeable with a 50A locking RV connector.




Complete cord: extension, detachable or hardwired?
Valterra A10-3025E is a 25-ft 30A extension with TT-30P and TT-30R ends. A10-3025ED is the 25-ft 30A detachable cord with TT-30P and L5-30R ends. A10-3025END is a 25-ft 30A cord with a TT-30P source plug and a vehicle-side end intended for permanent installation. These cord types are not substitutes without confirming the RV's original connection.



Before deciding to replace a damaged molded end, check the whole cable, outer jacket, strain relief, mating inlet and signs of heating. Replacing a plug alone cannot correct a loose or heat-damaged inlet contact. Have an appropriate technician inspect the assembly.
RV-side locking connectors and rings
Valterra A10-30FDTVP and A10-50FDTVP are separately catalogued 30A and 50A twist-locking RV cord connectors with rings. Marinco 6364CRV belongs to a traditional 50A locking connector family. Choose the exact mating profile and retaining hardware; the electrical rating alone does not make a SmartPlug, a Marinco connector and another twist-lock connector physically interchangeable.

Replacement shore-power cord ends and hardwired connections involve hazardous voltages and require the manufacturer's approved terminals, strain relief and cable ratings. Use a qualified electrical technician for connection work and inspection.
