AC vs Microwave Use
I have a Jayco MBH23 and we love it but when we use the microwave we have to turn off the AC as the both of them pull too much power when used together. Is there anything that can be added or corrected to get the 2 to work at the same time? We are totally new at this but love this trailer.

I can run the A/C and the microwave at the same time. However if the water heater is set for electric and it comes on that will trip the breaker. Other things that could put you over 30 amps if they were on at the same time would be a toaster, hair dryer, coffee pot, electric space heater, large fan connected to an outside outlet or your battery is low and charging heavily.

Is it tripping the breaker in the rv or where you're plugged into, or on generator?
Another item to add to the above list is refrigerator. We sometimes switch ours over to gas to run other electric appliances, then back to auto.

It is tripping the breaker in the RV not at the main power box.

Even though our 5er is only 30amp service, I use a 50amp pigtail and plug into the 50amp service on the pedestal when available. That seems to have helped a lot. I also have a voltage booster device that can boost park voltages when needed. Between the two I have drastically cut popped ckt breakers.

What type of voltage booster do you use? That makes a lot of sense.

The 50 amp outlet will not help adelldu4's situation as he is tripping the RV breaker, which is a 30 amp, not the pedestal breaker. The voltage booster should only be used if the supply voltage drops and stays below 110V.

The 50 amp outlet helps me...using the 30amp by itself the ckt breaker would pop on the pedestal. Having to go outside to reset. Using the 50amp outlet, the breaker pops in the rv itself...save me the trip of having to go outside to reset.

Here is another voltage booster.

This will not help in this situation that adelldu4 is encountering. It is in the TT's main breaker box, not the power coming from the shore power pedestal. If it were AC source problem, the pedestal AC breaker would open first. These types of units mount before the TT's fuse panel.
Nice unit though
Just my thoughts,
Don

Does not exactly cover the topic...but, another thing that helps prevents popped ckt breakers. Most pedestals have a plug for 120v service. I always run an extension cord from the pedestal a power strip for external 120v use, such as ice maker, fans, broiler ovens, griddles, etc. etc. etc.

Just as a reference, I use the 30 to 50 amp adapter all the time. Although my reason is because most of the 30amp outlets in the pedestals are abused, worn out or loose, since the 50 amp breakers get less use they are in much better shape.
Just my thoughts,
Don

Have not thought of that...but, makes sense!

but still
Back to the original issue. I've managed to trip the power at the post if I try to draw too much, but never in the rv. To avoid having to walk over and reset the breaker we try to remember to shut off aircon while using large draw appliances like the microwave.
Maybe the outlet you're connecting to is just a hair slower than the breaker inside.

you are possibly putting your shore power cord at risk. If a short was to happen between the pedestal and your break box inside, your cord, which is sized for 30 amps, could pull up to 50 amps, before tripping the pedestal breaker. This could result in a complete failure of the power cord. Plugging into a 50 amp breaker does nothing to get you more or more reliable power to your rig. If you have an issue with the 30 amp tripping on the pedestal and not in your rig, then I would alert the campground so that breaker can be changed, they can weaken over time. Breakers are there to prevent issues in your rig, they are designed as the weak link in the system, to prevent problems.

OP, we have that same issue. There really is nothing you can do to remedy the issue. Both the ac and microwave pull a lot of power when cycling on. Now we use turn the ac off or flip it to fan for the few minutes we use the microwave. In general you will not see a temperature change inside the unit.

You can probably use the AC and microwave at the same time if you run both the refrigerator and water heater on electric.

Don't you mean "run both the refrigerator and water heater on propane"?
