newby here - help with a/c 
Hi all,

Just moved into a camper i bought to live in while i build my house. Having A/C trouble that I can't figure out. A/C will run for a while but then kick the breaker. It seems to cool the 30ft camper just fine for a while then the breaker kicks. It seems to last longer when the days are not so hot or when i turn the thermostat up to 75 or so. It has run as long as 5 days without kicking but has also kicked after a few hours. The power flashed last night then came right back on. I heard the air kick on, then an audible "buzzing" sound, then the breaker kicked. I flipped it back on and it's been running ever since. It's on a 20 amp breaker in the panel in the camper. I've switched out the breaker (twice) but that had no impact. I had an A/C man come out but he couldn't find anything wrong with it and stated it's not pulling high amperage or anything. He did state that his specialty is home HVAC units and he doesn't really have experience with camper units or wiring.

Is a 20 amp breaker normal for the A/C? I'm reluctant to switch out to a 30 amp.
Any ideas as to why this is happening? It's a duo therm unit. The camper is old, '96 model. I'm not sure if this is the original unit that came on the camper or not. I really hate to invest in a new unit since this is being used as a temporary residence.

Any advice would be greatly appreciated. It's only going to get hotter in Tennessee the next couple months. I could be in for a long summer if i can't get this figured out.

thanks!
