Customer complaint
What the customer noticed
Turning on the air conditioner immediately tripped both the camper's breaker and the breaker supplying power from the customer's barn.
Diagnostic findings
What inspection and testing revealed
Electrical testing showed that the camper had been connected to 240 volts instead of the required 120-volt, 30-amp RV supply. The incorrect voltage damaged the converter. Testing of the remaining 120-volt and 12-volt systems did not reveal additional damage.
Work performed or recommended
What Sunset did or recommended
Sunset traced the repeated breaker trips to the incorrect power supply, tested the camper's electrical systems, and identified the converter as the damaged component.
Outcome and next step
Where the service call stands
The cause was confirmed and the owner was advised that the failed converter required replacement. The remaining tested systems checked out correctly.
