Unhappy Shumacher 55A converter breaker issues

Brand new to site! I own a Winnebago view 2013 24V bought used and owned for 1.5 years. When connected to shore power 30A in cold weather daytime 55, night close to freezing, the 20 A breaker labeled microwave trips causing electric heat to go off. Main never trips. Fridge & wtr heater on LP. Could it be bad breaker? Loose connection at breaker? This also happens when using MV with heat or air on hotter days ~90. If breaker is suspect where can I find replacement breakers for this unit?

Shumacher 55A converter breaker issues

I'm having a hard time trying to figure out what you are saying. 24v??? 30 amp??? 55 amp converter? Each one is a different fruit. You need to compare apples to apples. What does your converter have to do with anything other than it can be a huge draw on AC.


Is your RV 30 amp or 50 amp?
Is your shore power really 30 amp or a 20 amp you plug in to with your RV cord and an adapter?
Are your circuits properly labeled?
What is the amperage of your main circuit beaker?

The circuit beakers can be found at any home improvement store, they are not unique to RV's.

Electric heater and microwave on 30 amp circuit oops possible. On 20 amp circuit definite oops. Plugging into 20 amps definite oops.

Find out what you have for AC. Label each circuit using a circuit tester. Add up your wattages of devices you use.

If you have a 30 amp system you can usually only run one major AC appliance at once.
If you are plugged into a 20 amp outlet you might find certain AC appliances won't work, they will pop circuits. If you have 2 or more major AC appliances on a single circuit and use both circuit breakers will pop.
