SOURCE: Breaker trips on roof top RV A/C

check your breaker is it hot to the touch?
check the wire tightness at the breaker?
remove the circuit breaker and inspect the terminals on the breaker and in the panel and the breaker itself for signs of overheating and discoloration due to the fact
check the connections at the unit itself
check that you have proper voltage to your unit
find the nameplate and look for FLA full load amp draw
is the breaker properly sized for the unit and is the wire size correct for the breaker?
(Check nameplate on unit)
buy a clamp on amp meter and see if it is under or over the nameplate rating when unit is running
take great care when you venture into electric,if you arent comfortable find someone who is.
you may have a weak breaker if all the above pass?
Replace it

SOURCE: air conditioner will trip breaker when trying to cycle back on

The compressor motor , once warm is grounding out due to wear and is going bad.Have the compressor replace while it is still clean is cheeper and easier that doing it after a burn out,which  will eventually happen,if the compressor is tripping the brreaker as I suspect..

The problem is that when u add up the electrical draw from all of these appliances running full bore, your draw exceeds your available amperage. Now you are doing the math and saying no...... Let me tell you why. It is rare to find a situation where a 100 amp service actually porovides 100 amps. You almost always have voltage dropo. And when you are adding extension cords to the mix the drop is even more. That said, When you are using the AC try to minimize the use of other appliances, especially the microwave which is a big draw too.

when the coils are dirty there is not a good heat transfer and there is little condensation of the refrigerant gas, the pressure in the condenser coil builds up too high and the compressor takes more amps, having the risk of geting burnt. Either the protector inside the compressor stops the compressor or the braker at the generator electrical wiring.
You have to make sure the coils are perfectly clean and try your ac checking the amps it takes when it is running, with dirty coils and with clean coils. and check the rated amps of the compressor at full load FLA

Either your fan is stuck due to age or grime or is shot

if the fan does not provide cooling then the unit goes into thermal protection mode and shuts down
