I really need to get off my butt and get another one.I have a 30amp one from our last tt but since getting this 50 amp fiver a yr ago I havent had one due to the fact I like having all 50 amps available to use.I know I spent some serious coin on the 30 amp one.What is the difference between the very expensive outdoor ones and inexpensive outdoor ones.The joule rating?All of them will protect from low voltage correct?
