excel windsor 120/240v confusion

[lightmind]

Hi,
I am working on a friend's excel rv. It has a label on the electrical receptacle that says "this connection is for 110/125 volt ac, 60hz 50 ampere supply". There is a double Pole 50 breaker inside wired with two hot legs and a neutral. I can wire for 240v 50a but am hesitant because of the label saying 110-125v, anybody know why it would say 110-125v instead of 240v? Seems that the 110-125 would be only 30a max....
