Man, I don't know how everyone else is set up but we use our microwave and A/C at the same time without any problem. Our new Wildcat has a 15K A/C. We also didn't have any problems with our old 2004 Wildcat and the two are not on the same breaker. Look for other usage that might be causing the problem. Were you using the hot water heater on the electric side? Did you have the TV on and the coffee pot running while using the A/C and Microwave?

I just sold our 2006 Wildcat 29RLBS. Would trip the internal breaker all the time with AC and Micro IF hot water and/or frig was also on AC and happened to be running. Our solution was to dump off refer to gas and hot water AC off. Then we did not trip breaker. Just because you have 30 amps coming in does not mean that everything can run on AC at same time. Conversion to 50 AMP is a really big deal after the fact and limits you to two separate 25 amp systems. You still have to manage how much power you consume at any given time.

If you're tripping the 30 amp breaker, you probably have the water heater on electric too. If it is just a breaker inside the trailer, it is possible the air cond and microwave are on the same breaker and the advice to add a breaker should solve the problem. By the way, a 50 amp service is two 50 amp circuits; not two 25 amp circuits.

We bought a Voltage Meter at Camping World and keep a close eye on the voltage to make sure that it's safe to run our electrical items.
We have camped at a couple of older campgrounds that do have 30 AMP service, but the voltage was way too low to run either the microwave or AC by themselves, let alone both of them at the same time.
One place we camped the voltage was so low that we couldn't even run the coffee pot! We had to kept the frig and the hot water heater on propane our entire stay.
You need to get a voltage meter and keep an eye on the voltage before you turn on any electrical items.

Keep in mind that one of the most overlooked culprits of using too many amps is running your hot water heater on electric. For years, hot water heaters didn't have the electric feature on a 30 amp coach. Ever wonder why?
Our KZ is 50 amp and I have yet to use the hot water heater on electric. We have a 12 gallon hot water heater and when we need hot water, we flip the propane switch on and within 5 minutes or so, we have hot water. When we're done, we flip it back off. No need to run it constantly in my opinion.
Hot water heaters use way too many amps and are very often forgotten about when switched on electric.
Just my 2 cents...

Just think of it as doing your part to "Going Green". You have to watch your power consumption, water-consumption, Waste management, etc. I know it seems a little annoying if you are used to your house with a 150Amp service panel, endless water supply, and permanent sewer connection. But remember your house ain't on wheels.

And some basic knowledge of how electricity works AND how to wire up a new panel. For instance, why would you connect the two 50 amp legs (100 amps) to a 60 amp panel? If a person doesn't even know why his CB is tripping I doubt he would know how to wire a box.

It was mentioned in this thread "welcome to power management". I couldn't agree more. A 30A supply isn't really sufficient to supply all the appliances that can be used on a trailer. The very first thing everyone needs to remember is that your power converter, consumes about 5 amps of current continuously. That leaves about 25 amps of useable current for all the other devices. A 13.5K A/c unit draws about 15 amps, the water heater draws about 10 amps, the fridge draws about 3 amps and the microwave about 10 amps.
I make compromises by putting the fridge and the waterheater on gas, that way I have about 12 or 13 amps of current available or other uses. Our 5vr has a 15K A/c unit and it draws close to 20 amps of current so having our waterheater and fridge makes sense, because I still have some current capacity available for other uses.

We don't have any trouble with ours. Our fridge is a residential fridge so it's always on electric. We run our AC, microwave, sometimes 3 televisions, and several other appliances at the same time without any issues. The only thing we cannot do is run both AC units at the same time, but our coach has a systam that will alternate power between the 2 units so they both run just not at the same time. The only time we have any power issue is when we plug into 15 or 20 amp. When this is the case we just have to turn off AC when we use the microwave.

Which breaker? If you are connected to the house on a 20 amp circuit, you will not support the A/C and MW at the same time. If it is in the trailer, found out why they wired the MW and A/C to the same circuit. Not the right way to do things.
Out old trailer has the wiring separated such that we can run the A/C and MW on separate circuits and keep cool while cooking.
