Valterra 50 Amp Male X 30 Amp Female RV Adapter Plug

The Valterra A10-5030A adapter plug is a compact 50 amp to 30 amp RV adapter. It features a 50 amp 14-50 male plug on one end and a 30 amp TT-30 female receptacle on the other, without an additional cord section. This allows a 30 amp RV cord to connect directly to a 50 amp pedestal outlet in a very small form factor.

Because there is no dogbone cord, this style is easier to store but places more mechanical load on the receptacle. It is best used where the pedestal outlet is in good condition and you need a quick, compact adapter.

FAQ

Q: Why choose this instead of a dogbone adapter?
A: Choose this when space is tight and you want the most compact adapter possible, and the pedestal outlet is robust enough for the extra mechanical load.

Q: Does this change my RV from 30 amp to 50 amp?
A: No. Your RV remains a 30 amp system. The adapter only changes the plug style and lets you use a 50 amp outlet.
