50 amp rv outlet wiring

50 amp RV wiring is different than say a 50 amp clothes dryer outlet or an older stove outlet. 50 amp RVwiring is four-wire (ground, neutral, hot, hot) and uses a 14-50R receptacle. The older 50 amp clothesdryer outlet is three wire (neutral, hot, hot) and uses a 10-50R receptacle. Older stoves use a three-wire10-50R receptacle while newer stoves will use the very same four-wire 14-50R receptacle the RV uses. Thedifference (and improvement) of the 14-50R receptacle over the 10-50R is the addition of the ground wireand note that it is not special or unique for RVs.
