roof A/C TRIPS 20 AMP BREAKER
WORKING ON ROOF A/C it runs and is cold for about 15 to 20 minutes and then it trips the 20amp breaker that it is connected to. trailer breaker box. I was thinking possibly I should use a 30 amp break...

Possibly a "poor" starting capacitor. On the initial start, the system pressure is likely low / lower and allows the unit to start within the current rating. Probably after a bit, the A/C has cycled off and then attempts to restart. The increase in "head pressure" potentially causes an increase in current required tripping the breaker. Just a guess... as others suggest, try replacing the breaker and see if things change and go from there.
