I have a 50amp/220V outlet in my garage at home. When I plug in at home, I use the adapter shown below. It utilizes only one of the two 220v hot wires. Given my 50amp circuit in the garage works off two 25amp circuit breakers in the house, it is easy to concluded that it provides 25amp service to my PC.
.....two 25amp 110V breakers ganged together will provide one 25amp 220V outlet, not 50amp.

Correct me when I got my story wrong. I am no authority on this stuff. I thought 25a/110v + 25a/110v = 50a/220v. But you say it goes 25a/110v + 25a/110v = 25a/220v.I will have to study what I have in my main breaker box more closely. I thought I had two 25 amp breakers. Maybe I got it mixed up as to what I have in the house. I do recall the fellow who initially wired my garage had a different style 220v receptacle in there, later switched to this style to accomodate the RV adaptor. Do the different style receptacles have different power ratings?
So Bob, if both a 30 Amp and 50 Amp are available, it's safer to use the 30 Amp outlet rather than the 50 Amp with an adapter?
