Yes, it is a 240v outlet, with a ground and a neutral (4 connections total). The RV appliances will draw 120v from either side of the outlet (L1 or L2), depending on the circuit breaker arrangement in your load panel inside the coach.
This diagram might help:
Whoa, whoa, whoa folks, lets stop the panic here. This above is the correct way to wire the RV outlet. Yes this is a 220v plug, however the cable from the RV to the plug and the RV wiring system is designed to only pull 110v off either side of the 220v outlet. ALL, repeat ALL RV's are 110v and pull 110v from one of two 110v legs on a 220v outlet. Usually, one leg goes to all your 110v outlets in the camper and the other leg goes to the AC.
The wiring size of #10 is too small, I used #6 wire. I wired my 50amp outlet two different times myself. Once a few years back and most recently as a result of installing a new 40X42 building. I had a Journeyman Electrician check my wiring and is was just as it should be. I've run both my AC's off of this outlet with no problems and have not fried anything.
Electricians with NO RV experience do not realize the (2) separate 110V busses are independent and cannot be ganged to make a 220 outlet as in a residential breaker box.
