Hey folks... When we plug the camper into the house power supply, the lights and AC kick on fine, run for 5 to 15 minutes, then it trips the house breaker and a beeeeeeep alarm goes off in the camper. If I switch the breaker, it works again for a while. Any thoughts? BTW the cabinets are disassembled so I thought some wiring may be shorting. Didn't find anything obvious (like a hot wire laying around). Not sure why it would work for a while, then quit- versus just shorting out immediately if it was an actual short.
