Tripping Breakers !!

I have a 2011 298 BHD Crusader. We have camped at least once a month in it since new in July of last year. In that time frame the 30 AMP main breaker has tripped at least six times. And sometime the 20 AMP A/C will trip. This past week we were in it from Thurs-Sun. Fri afternoon the main tripped. Flipped it back on no more probs. Sat afternoon the A/C trips off. Flipped it back on no more problems. Granted it was well over a 100 degrees outside both days. I was plugged into a 50 AMP service using a adapter to plug my 30 AMP shore power in. It has done this at many differnt RV parks all over the place, with the temp being anywhere from 80-103 outside. It makes no difference if I am plugged into a 30 AMP, or 50 AMP. I am affraid to go off for any leanth of time and leave my dogs inside.

What other items are running?
Your close to 30 amp with a/c's alone.
Search "normal appliance draws" here on frf To track down you total amp draws.

Please find this issue! We seen a few months back a guy kept tripping his breaker and it was found to be bad and almost ready to catch on fire!
I'm sure herk has a pic

Regardless whether you're plugged into 50 or 30A, your camper has only 30A available to use. The 13.5K A/C uses 12A alone to run...the 15K A/C more yet. Add the WH at 10A, any other appliance and the 30A is maxed pretty easily. You perhaps need a amp load readout as I have on my hard-wired surge protector to know where your consumption is and avoid the trips.

You might take a look at the campground voltage at your site. If it's hot out, there's going to be lots of campers with A/C units going that will drag the voltage down. Then you can have trouble with your A/C starting and even tripping either the 20A, or the 30A main if you have other heavy loads running at the same time (micro or coffee maker or toaster, etc).

You could use either an inexpensive multimeter or get one of the plug-in voltage monitors (Camping World, eg.).

We just left a c/g where the voltage got down to 104V during the day. Not very good.

We took ours out for the first time this weekend and it was doing the same thing. I had to use gas for the WH.

The low voltage was causing your problem.
We covered this at length back in July.

I will track down the thread.

Low voltage and air conditioning

Do you use a Power Surge Protector?

As voltage is reduced from heavy usage in park your amperage goes up in oposite and equal proportion. So yes that can easily trip your 20 or 30 amp breakers quickly.

Ohms Law E=I X R

You have your AC on and you have 2 refrigerators?

Sorry but I must ask if the 2 fridges are built in or ?

Thanks
I still believe it is a low voltage problem.
