How to find the right RV Plugs, Inlets & Receptacles AI guide

What the AI looks for in RV Plugs, Inlets & Receptacles
- NEMA configuration
- Identify your rig: TT-30 for 30A 120V, NEMA 14-50 for 50A 120/240V, or 5-15/5-20 for 15/20A household. Replacement plugs and receptacles must match exactly. Wrong configurations either won't mate or can deliver the wrong voltage.
- Inlet type and fit
- Match the existing inlet's amperage, locking style (standard or twist-lock/smart-plug style) and flange or cutout size. Shore cord heads are specific to the inlet system, and a different flange won't seal the existing hole.
- Wire termination range
- Confirm the plug or inlet accepts your cord's conductor gauge: 10 AWG for 30A, 6/8 AWG for 50A. Loose or undersized terminations are the most common cause of melted plugs.
- Weather sealing
- Prefer inlets with gasketed, spring-closed covers. Water intrusion corrodes contacts and causes heat.
- Listing
- The part should carry a UL or ETL listing. These parts carry continuous high current.
Brands that matter
- Marinco: Widely used locking inlets and replacement plug heads.
- Furrion: OEM-installed inlets on many towables. Buy matching Furrion heads.
- SmartPlug: Locking, weather-sealed plug and inlet system sold as a retrofit set.
- Camco: Common replacement plugs and receptacles in standard RV configurations.
- Hubbell: Electrical-grade NEMA receptacles for pedestal or home RV outlets.
What to avoid
- Wiring a home RV outlet with a dryer (10-30/14-30) receptacle in place of a TT-30
- Reusing a plug whose contacts are discolored or blackened
- Installing a home pedestal yourself without confirming TT-30 is wired 120V
Questions
Is a TT-30 outlet 240 volts?
No. TT-30 is 120V only. It is a 240V miswiring that destroys RV electronics.
