Seen a few of these, but none match exact to issue. Roo 233 plugged into 30 AMP service. Fridge and WT running on Propane. With AC running the breaker pops with little or no other load (no microwaves or hair dryers), maybe a cell charger plugged in or coffee maker.
If Fridge is running off electric service the AC Breaker will pop everytime after 15 or 20 mins of use.
Any thoughts. Only option I have come up with is to replace breaker.
Coffee makers use a lot of current. Is the water strictly on propane, or electric also? Are you tripping the camp ground breaker, or the one in the trailer? If in the trailer, the MAIN or the AC one?
