55 amp at 14v DC charge approx 700w, approx 8 amps 120vac input power
30 amp at 120v , 3600w Max power for RV,
A/C 1400 to 1800 Watts depending on the weather
MW 1000 cooking Watts. 1450 input Watts
RV fridge on electric 340 Watts
It's the power , not the amps , volts * amps equal the Watts power
Two different voltages , comparing apples to oranges
50 amps 120v would not have hurt the RV
I think you mean you plugged to a 230vac socket, either a dryer or welder socket
There have been a number of members who have done that so far this year, a few of them it was the correct socket wired wrong by the electrician
The rest somehow managed to to force the RV plug with round ground pin into the 'L' shaped ground on the dryer plug
If the pins don't look right, don't try using that socket
