Breaker keeps tripping

[DonYargeau]

Hi,
We have a 2018 Thor windsport 29m, we have it plugged in to house power, 20 amp breaker. The breaker trips at odd times , eg; wife went to bed everything , electric heater lights tv etc working fine, woke up turned on Only a tv and circuit pops. Last week she flushed the toilet, nothing on and it popped.
I’m suspecting batteries or inverter. Anyone have any suggestions or other things to look at ?

Thx, Don

Is the breaker tripping as a ground fault or overload?

20 amps isn’t much. Especially if you are running a space heater in your coach. You’re probably drawing close to the max sometimes and a random set of events may trip the breaker. For example if your heater happens to turn on just as your converter switches out of float mode the spike might do it. And if it’s an old breaker on a circuit with other things in your house it gets even trickier. If you plan to keep your unit at home and plugged in it would make sense to upgrade or add a 30A outlet dedicated to it.

are you tripping the GFI outlet or a breaker? GFI outlet will not trip on overload.
