OK, I'm an EE, retired.
Circuit breakers will trip just in time to protect themselves and burn out anything down stream.
If all you needed is the circuit breakers then why buy a surge protector?
In a proper electrical circuit everything must be sized and rated as required.
The surge protector is there to guard against Brown Outs, high voltage and spikes. Spikes, you know, what you get in a poorly designed campground when someone or a bunch of someones connect or disconnect.
Look, size devices for need not wishes.
But then RV salesman say my Silverado can pull a 32" camper.
