If only the AC (air conditioner) breaker is tripping it is not because you are exceeding the 30 amp limit. It could be that the AC is drawing a high current because the voltage to it is too low. Maybe a loose wire, or the breaker may be failing.

It's not just the AC. The whole TT goes out.

You need to verify that the incoming line is going to the 30 amp breaker and the AC unit is connected to the 20 amp breaker. Sounds like it could be miss wired.

Any time 'any' breaker trips I ALWAYS shut all breakers off and then back on again. Some of these get tired and they don't trip all the way and creates resistance and trips again. Not to mention it can start a fire. Don't ask me how I know this.

Also the GFI that the micro is attached to wears out real quick and even though the buttons are in it still can be tripped and it's time to replace it.

I bet if you reset all the breakers you should be fine. When you do this you will also 'feel' which ones are loose and don't hard snap back and should be replaced.

DITTO! And if the humidity is real high and the AC ices up it will also trip the breaker. For this case you need to run the fan on continuous (not auto) and high fan.

zackyboys3rs, are you at a campground or at home? If you are at home and using an extension cord to power your RV that could be the problem. If you are using an extension cord, how long is it and what size wire is it made of? Inadequate extension cords are notorious for causing problems.

Terryallen wrote that the whole TT goes off. I understood you to say that the AC breaker trips. Could you clarify this?

Yes, just the AC breaker trips. Sometimes the GFI trips separtly. I am at home now. Camper is stored at campground.

Not much has been said about the GFI tripping. I doubt that the GFI problem is related to the AC. GFIs are prone to trip due to moisture in any of the receptacles that they are connected to. You might want to check the outdoor receptacles to see if water has gotten into them. If not that, you could replace it and see if that stops the problem.

For the AC problem, if you have a voltmeter, check the voltage with the AC on.
