There are a few different 50 amp style connectors. The ones for RV applications use the 240 volt twist lock style of 50 amp outlet (NEMA L6-50) a lot which has three prongs whereas the 120 volt style of 50 amp connector you are thinking of that has 4 prongs is the NEMA 14-50 and is commonly seen for electric ovens.
