55225 Adapter, 15/30 A, 125 V

Converts a standard NEMA 5-15R duplex receptacle to a single TT-30 receptacle. It allows a 30 A RV to be plugged into a 15 A outlet - ideal for both residential and generator use. The adapter reduces receptacle overheating by using both receptacles of a duplex outlet. This allows cooler operation during peak loads. The top 15 A plug adjusts to fit both standard and GFCI receptacles. This product features two (5-15P)/TT-30R connection and is rated for 125 V/1875 W.
