First you have not one protection device but two.
First is a circuit breaker. this is what worries about the "Amps" if it's a 15 amp breaker a 20 amp load = the click of darkness (Tripped)
Then you have the GFCI. it does not care about amps. it carries about mA (Thousands of an ampere or amp/1000) if the difference between the current on the black and white wires is more than a few mA different.. you get the click of darkeness.
many RV's do not play well with GFCI.. I know how to cheat and make them play nice but... cheating is not without danger so.. Sorry. I will not tell.
But any current leakage to the GREEN wire (Safety ground) or any other path to ground (Such as your body) trips the GFCI.
Finally.. GFCI's are required by law for 15 amp outlets in areas where there is a moisture danger.. Kitchen, bath, outdoors, garage, and so on.
