When you say it "pops" are you referring to the circuit breaker feeding the home outlet to which you are connected?
Sounds like you've got a load on that you don't realize.
Water heater? Engine block heater? Water bay heater? Something plugged in and left one that you didn't realize?
If you're plugging in at home, and tripping the breaker in the house's panel, the first thing to consider is whether you have something else plugged into the same circuit (in the house, not in the coach) that when combined with the load of the coach it becomes just too much. So don't forget to consider everything else that may be on the circuit, don't focus only on your coach.
If you have all of the "home" loads disconnected except the coach, and you're still tripping the breaker, try this sequence:
- Unplug
- Go into the rig's AC breaker panel and shut off every breaker, including the main breaker.
- Plug in, leave all of the breakers off. Does the problem breaker trip?
- Turn on just the main breaker. Does the problem breaker trip?
- Turn on the first individual branch breaker -- just the one. Does the problem breaker trip?
- Turn off the previous breaker and turn on the next one -- repeat for each breaker. Do any of them trip the problem breaker?
The idea is to divide and conquer. Start with everything off, and turn things on one by one. Give more than your troublesome 10 seconds to see if it will trip the breaker before you go on to the next one. At some point, turning on a breaker should cause your troublesome circuit breaker to trip -- that will be the circuit that has the excessive load. See what is on that circuit that is drawing too much power.
Of course, it's possible that you could get through all of the circuits one at a time, and not end up tripping your troublesome breaker. In that case, it's not that one circuit is drawing too much, it's a combination of circuits that add up to too much.
