Marinco ParkPower RV Power Inlets: 15A, 20A or 30A?
A small shore-power inlet is not interchangeable with every other covered inlet. Marinco's 15-amp and 20-amp designs use straight-blade power connections, while its 30-amp detachable-cord model uses a locking connection. Compare the exact part numbers below before replacing a damaged inlet or planning a new installation.
Identify the cord connection first
15A / 125V — straight blade
Look for a standard 15-amp grounded straight-blade plug and matching inlet. Marinco's black and white options are 150BBI.RV and 150BBIW.RV.
20A / 125V — straight blade
The 20-amp format uses a different matching plug configuration. The corresponding variants are 200BBI.RV and 200BBIW.RV.
30A / 125V — locking
The 301ELRV family is a separate detachable-cord inlet using a matching 30-amp locking connector. Select white 301ELRV or black 301ELRV.BLK.
Amperage and voltage are both part of the connection specification. A straight-blade 15A/125V plug, a straight-blade 20A/125V plug, and a 30A/125V locking cord end are distinct designs. Colour alone does not establish electrical or physical compatibility.
Safety and fit: These are power inlets, not adapters that change a campground's available current. Match the complete plug-and-inlet configuration, existing circuit protection, mounting dimensions, wire termination and grounding. Shore-power wiring should be installed or inspected by a qualified professional using the manufacturer's exact instructions.
Marinco RV power inlet comparison by MPN
All six listings are covered 125-volt inlet assemblies. This chart distinguishes the published nominal electrical rating, connection style and housing colour; it does not imply that the mounting cutout or internal wiring is identical across models.
| Manufacturer part number | Nominal rating | Cord-end style | Cover colour |
|---|---|---|---|
| 150BBI.RV | 15A / 125V | Straight-blade | Black |
| 150BBIW.RV | 15A / 125V | Straight-blade | White |
| 200BBI.RV | 20A / 125V | Straight-blade | Black |
| 200BBIW.RV | 20A / 125V | Straight-blade | White |
| 301ELRV | 30A / 125V | Locking | White |
| 301ELRV.BLK | 30A / 125V | Locking | Black |
What to verify on the old inlet
Match the original identifier. Check the part number or electrical rating on the original inlet, then compare the actual mating face to your shore-power cord. A similar outside cover can conceal a different blade arrangement.
Measure the installed housing. Check opening diameter, flange shape, fastening locations, access behind the wall and room for the rear enclosure. Never enlarge an opening or move fasteners based solely on the nominal amperage.
Inspect the complete circuit. Burn marks, heat-discoloured contacts, a cracked cap or loose terminals are signs to have the inlet and mating cord end checked. The replacement must not bypass existing overcurrent or ground-fault protection.

View inlet detailsHow these fit into an RV shore-power system
The inlet is only one piece of the power connection. A complete installation may also include a detachable cordset, correct protective devices, a distribution panel and, in some systems, a transfer switch. See the RV shore-power and electrical protection guide for the bigger picture.
For other connector families, including 30A and 50A detachable systems, compare the SmartPlug and Marinco shore-power identification guide. To recognize common campground plugs, use the NEMA 5-15, TT-30 and 14-50 plug reference.
Common inlet-selection questions
Can I plug a 20-amp cord into a 15-amp inlet?
Do not assume so. The 15A and 20A configurations differ. Match the exact mating connector, electrical rating and manufacturer requirements.
Is a Marinco 301ELRV a standard household power inlet?
No. It belongs to the 30A/125V locking shore-power connection family. Use the proper compatible cord end and installation components.
Will a black model fit where a white model was installed?
The same series may offer a different colour, but still verify the exact inlet number, original mounting footprint and connector configuration. Do not select by colour alone.
Do these inlets provide built-in GFCI protection?
No integrated GFCI device is listed for these six product records. Any required circuit or ground-fault protection must be provided by the appropriate electrical equipment for the installation.
