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...

The 30/15 is a split breaker. The 30 is the main and the 15 is a branch circuit.
I would check the neutral(white) wires in the back of the 120 volt distribution panel. A loose connection causes increase in resistance and voltage drop.
Pick up some electrical grease from your local hardware store.
Disconnect from electrical source
Disconnect each of the neutrals one at a time and inspect for dark coloration of the wire.
Apply a liberal amount of the electrical grease(de-oxidation) to the conductors.
Re-connect wire.
Do this to your branch wires and incoming wires that are attached to the breakers.
DO ONE AT A TIME!
Don't forget to disconnect from electrical supply!
