A 50 amp rig uses 240v with 4 prong plug - hot, hot, neutral, ground.
Which plug is on your rig.
Adapters are available in both directions to safely plug into the opposite socket...
A 50a to 30a adapter will plug into the 50a 240v, and connect only one hot lead thru to the 30a socket.
A 30a to 50a adapter will plug into the 30a 110v, and bridge the single hot lead to both hot leads on the 50a socket. (Doesnít truly give 240v, but most of our rigs donít truly USE 240v...
I canít speak to what is used in Mexico though...
