Phil is right, from a technical standpoint. The wiring is not rated for 80 amps. But assuming a system will use 80 amps isn't right either. Unless you have something wrong (like you parked too close to a tree), the pump should not draw anything near 80 amps. I suspect a 55 amp breaker would probably cure most people's problems but there is no such animal that I'm aware of. We need to also keep in mind that a momentary sticking point in the system that causes the pump to draw more amps isn't going to burn the trailer down. The wire will get warm, but again, unless you are against the aforementioned tree, it won't get red hot, melt and start a fire.
