Juat purchased a new MH and will be using a 50/30 amp adapter occasionally. the 30amp plug has 3 blades, the 50 amp plug has 4 blades.
How are they wired internally so as to maintain 120 VAC??
With the 50 having two hot legs of opposite potential and thereby supplying 240vac to the coach, only one of these legs is connected to the hot side of the 30amp receptacle end. The neutral connections are the same, as is the ground.
With my 30amp service, I've replaced the plug with a 50amp model and obviously use only one hot connection. I like the heavier blades in general and now carry a 30/50 converter cord instead. The 30/50 converter jumps the two 50amp blades together and in my case one of them goes nowhere. With a 50amp coach, a 30/50 cord supplies both sides of the breaker box, even though of the same potential, which results in the loss of any 240v requirements.
