Single phase 240V - what happens if one plugs an RV into 2 phase power?

[Gary RV_Wizard]

The Tiffins I mentioned above include their mid-range diesel pusher, so not exactly a "high end" coach.

As the popularity of "all-electric" coach designs with induction cooking and electric dryers increases, you can expect to see more coaches offering the possibility of 240v appliances. Including gas chassis models.  There is nothing inherently expensive or high end about it; once you have 50A service you have the capability and the appliances don't cost any more.    From there, it's mostly just a matter of market demand. Those who want to retain max flexibility for off-grid camping will probably stick with 120v/propane hybirds, but the increasing number of RV travelers who stick to full hook-up campgrounds makes all-electric rigs a popular and viable choice.

just a point of clarification house electric is usually single phase meaning 2 hot legs one neutral and one ground so in your house, you get 120v by using one of the hots a neutral and a ground for safety.  To get 220 you use the two hots and a ground no neutral.  3 phase is usually found in a commercial setting there are two types y and delta.  y is 3 120 legs a neutral and a ground. Delta is usually found in a factory and does not have a neutral so no 120 v. Electricity can be very trickey always check with a meter because if you make a mistake it can be deadly or at the very least you will find out that electro shock therapy works

You would need a 4wire plug to be able to have a neutral and ground
