30 amp to 50amp Adapter
Can a camper with 30amp plug in to 50amp service with a adapter? what would happen? Its still only receiving 120volt right? or No.

In reviewing the response from RoyB note that the 50A service is 240 single phase AC with two hot legs at 180 degree opposite phase .at the 30 A end (see his sketch ) only one of the hot phases is connected ( 120v and neutral ). Accordingly, only the breakers in the RV Load Center connected to that phase can be operated. Breakers in the Load Center connected to the other phase bus bar are thus not powered and their connected loads will not receive power per the sketch.
Look again. The 50 is the male and the 30 is the female. The 30 male mate for it has a breaker box with all the breakers connected to this one hot leg.
If it were the opposite like you're thinking, then there would be a jumper across the hot legs of the 50amp female and thereby providing power to both legs in the box, even though of the same potential and limiting usable power to 50%.
