Help, Shore Power CB Keeps Tripping

Why does the shore power 30 amp circuit breaker keep tripping? I'm running my refrigerator, water heater, and air conditioner, along with one TV at the same time. Is that enough to trip the 30 amp circuit breaker?

We have had the same thing happen 4 or 5 times since we've had the 2015 Flying Cloud. I thing that the electric water heater function is the culprit. We had over 1,500 nights in our 2005 Safari, and it never happened. In the 2005 the water heater was gas only.

These are current draws as measured by my surge protector:
AC 13-14 amps depending on size
Water heater 11 amps
Refrigerator 2 amps
Converter -- dependent upon state of battery charge

Hope this helps you.

My guess is water heater the load culprit, our 2012 did this. Our 50 AMP 2015 has not, with both AC running and everything else on including microwave and a hair dryer.

Try not leaving WH on all the time and see if it helps would be my suggestion.

Our mpg was a 30A rig, and our Foretravel is 50A. When we have to use 30A we have to carefully monitor power use. 30A is ~3600 watts. I'd suggest that you run the hot water heater on propane when you are running the a/c. Turn the a/c off when you run the microwave or coffee maker.

Simple answer is yes.
When in our MH I try to "manage" my power. We always leave the water heater off unless getting ready to do dishes or shower. We turn off other devices when not needed as well.
Best to do a survey and try to get a list of the appliances and their power draw. After you have that list this will all make better sense.

Did you try switching the water heater to propane?

Some breakers are weak and others get that way over time. If making a bad connection they can run hot and trip easy. Also if in a hot environment they can trip at a lower current. Feel the breaker to see if it runs hot. Try turning the water heater off when not needed. Would be nice to know the voltage and amps you are drawing when problem occurs.

An important thing that many people don't realize is that you should not use more then 80% of a circuit breakers rated capacity for en extended amount of time. This means you should keep the load on a 30amp breaker below 24amps.

At least that is what I have been told by a couple of electricians.
