Going to my son's and he has had a 50 amp plug put in for us. I am a little concerned about whether he has attached it to a 220 line or 110. The breaker has two 50 switches. Can't afford to fry my 5th...
I agree on testing but I would have more concerns if a 30amp had been installed, way too many home RV 30 amps wired as 220/240 instead of 110 by so called electricians.
