Connect your RV or any appliance having a NEMA 14-50 plug, to an L14-30 twist-lock outlet using this adapter. Fully molded adapter with electroplated terminals for use in any environment indoors or outdoors. Although L14-30 outlets are typically rated for 30 amps, we made this adapter with ultra-heavy-duty 6 AWG pure copper wires which can handle up to 50 amps – this adapter is super-rugged and built to last. Includes 3-year warranty.
