On the way home from our weekend we lost house power.
When we got home I check the gen and found one of the breakers tripped.
I reset and house power was restored.
Anyone have experience with this and do you know the cause ?

Excess current.If you do not have an energy management system on the generator conductors you will have to do your own manually.

This has happen to me on rare occasions, never tracked it down to a cause, just reset and moved on. Couple of potential causes could be if you had recently checked oil in the generator and accidently hit the breaker but did not fully trip, hard bounce in the motorhome.

I would be surprised if it was excess current draw unless the generator is woefully underpowered. To exercise mine hard I turn on both air, microwave, toaster oven and whatever else I can and never tripped the breaker. Mine is 7500 watt which translates to ~62 amps

I have tripped the low side breaker on my 5500 watt genset a few times. Having too much load, ie microwave, cube heater, and toaster all running at same time will trip it. I have two roof A/C units, they are wired only one per each of the two circuit breakers of the genset. Rear A/C unit and microwave share a circuit from the genset, and will sometimes cause breaker to iterupt service on a hot day, if both used at the same time for an extended period of time.

On my Hurricane with an Onan 5500, It will trip the 20 amp breaker if I run the rear A/C and the electric water heater at the same time. I have to remember to switch to propane water heater when running the generator.

happened to my 6k in my Palazzo -
racked my brain to try to find out why
running the gen was not charging the
batteries!

I think/hope you nailed it. I have just had the generator serviced and did travel a rough stretch of road on the way home.
It's a 7500 that comes standard with the Allegro Open roads and we didn't have any more load than usual.

We've had it happen a couple times. Once on a 6.3Kw propane air cooled unit that overheated and then the 8.0Kw liquid cooled diesel in the Dutch Star. Never did figure out why.
The Magna has a 12.5 Kw constant speed gen and so far it's not happened to it, but we only put a few hours on it so far.

The breaker tripped because you had too much load on that circuit of the genset.

The front roof AC and the electric heating element for the water heater were both on the same circuit in the motorhome we had previously. One of the 2 breakers on the generator tripped every time we ran the roof AC if I forgot to turn off the switch for the water heater.

Might be easier to make a list of class A owners who have used the Generator and NOT had that happen.

THe Generator breaker can trip from a combination of load and VIBRATION...and it lives in a high vibration enviorment. Has happend to me many times.

Do not worry about it.. Just reset it.
