RGordon is absoulty right! I have been an Industrial Maintenance Supervisor for 10 + years. All it is 220 single phase its only two 110 legs with a ground wire where it ties on a buss bar in the box that is also a tie point for your nuteral on a 110 v circut. The AMP rating is how much draw it it can handel while working 30 AMP is normal for a house.
What isn't being mentioned when we discuss two 110 V legs is they have to be out of phase to create 220V service. My understanding is that the 50 Amp service we hook into at RV Resort/Park pedestals, the two 110V 50 amp legs are not out of phase and therefore 220V is never present inside the RV.
