inverter problems

Have shut them all off but still have the same problem. all of the receptacles work fine when plugged into my house receptacle but not into the inverter

Would cutting all your breakers first help isolate the issue? Is it possible it's an overload, like the WH is on?

Been there and done that. When I use the ground fault circuit, all the plugs work but when I use any of the others or my shore power cord I get a shut down fault. My inverter dos not like something in this new trailer wiring for some reason. I could live with it except my ground fault circuit is at the back and outside so not very practical. Still trying!

What gives you the error
The inverter
Or something in the TT ?

Also sound like you are using a back feed , suicide cord system
Since you said plugged into one of the Tt outlets

Since you are using one outlet
Try turning off all the the other circuit breakers
Then turn them on one at a time, see which circuit created the fault
My best guess would be fridge or water heater
Something with a heating element shorting out
I assume, you already turned off the converter

You could also check the breaker panel
Maybe somebody bonded the neutral to ground and the inverter don't like that

This is very common. Same as plugging it into a generator.

Is that what you're doing now? You can (and should) plug your shore cord into it.

Sorry, to clarify my problem I have always connected my inverter to one of the 120 receptacles in my trailer when dry camping. That way most of the receptacles have 120 power for my use without having extension cords to use my small appliances. It just makes life easier. For some reason the only receptacle that will work without faulting my inverter is the ground fault one which makes me think about the difference between Canadian and American rv wiring. Does that explain what I am doing?

Motormaster 3000 is an MSW. Something in your new RV doesn't "like" that. I fear you are back to using a dedicated inverter outlet and forgoing powering the "whole house".

I use two golf cart batteries to power an inverter when dry camping.*no power source available* Plugging the trailer into the inverter gives me power to run tv, toaster,blender etc.

Confused? Why would youlug your trailer into an inverter? Trailers are serup to plug into either a 30 or 50A receptacle. Inverters change 12VDC to 120VAC so you can run a few household appliances off grid. So please restate your question.
