There is NO amperage protection (only visual monitoring and display) of the amperage load. If you exceed the amperage, it's the circuit breaker, NOT the EMS, that trips to protect the circuitry. So, whether it's a 100 amp, a 50 amp or a 30 amp EMS, it does, as you say, protect against brownouts, surges, spikes, ground issues, hot neutrals, but it does NOT protect against amperage consumption. That's entirely left up to the power panel in the trailer (for trailer distribution) and to the campground circuit breaker for "upstream protection".

So if I’m understanding correctly, the trailer’s circuit breakers will protect the trailer from an amperage overload, the EMS will protect from a voltage overload (and all of the other above mentioned problems). That makes sense.
