Using A/C and Electric Water Heater

[Paul]

I was at my seasonal site over the weekend and while I was using my A/C + my Electric Water heater the campground breaker tripped. This happened twice. Once I switched Water heater to propane I was fine.  On a 30A circuit I should be able to use my Water Heater on Electric at the same time than my A/C?

Edit: Forgot to mention that I had my refrigerator on electric too

Paul,
You should be able to run the AC and the electric WH simutaneously on a 30A circuit. The WH is rated at 1440 Watts or 12A. The AC is something less than 15A after startup. The fridge is only a few Amps so the total is close but should not exceed 30A. The other item to check is the converter. If your battery was low the converter may be trying to recharge it. Since the main 30A breaker in your camper did not trip it may be the breaker on the campground pedestal is weak. They do get old and tired.
