A couple of months ago I posted a topic regarding our PU and the air conditioner popping the curciut breaker on the convert box. Have not used it, but did have the converter box checked and everything looked fine by a friend whom is a mechanic. Changed the plug t the box as well, today after three months of not using the PU my DH plugged in at the campground and when he put the air on High cool it popped within the 15 minute range. But after reseting the breaker, he placed the air on low cool and stayed on for several hours.

Does anyone have any suggestion of what is tripping it? Also several hours later he switched to the heater element and it popped again? Any more suggestions on what is causing the pop of the breaker?
We just had the roof replaced about 9 months ago, and I am wondering if something is touching inside the air conditioner since it was moved from one roof to another..
Need some suggestions and advice. We don't know waht to even look for.
Thanks for your help in advance, will check back tomorrow for suggestions.

Heater strips draw apx 12 amps. If the heat strip alone popped a 20 amp breaker which is the standard breaker for AC use; I'd have to say you have loose connection between the AC and the breaker or the breaker itself is bad and need replacing.

Also check the voltage coming into the pop up less than 220 but more than 120 will pop the 20 amp breaker. Trust me I know
