Final answer:
Before connecting an RV to shore power for a PDI, ensure all circuit breakers are off to prevent damage. Then, observe the power converter's operation to ensure it's working correctly.
Step-by-step explanation:
To avoid unnecessary drain on the RV battery during a Pre-Delivery Inspection (PDI) and to check the condition of the power converter, it is important to connect the shore power cord to a 120 V AC shop receptacle. However, before proceeding, be sure to verify that all circuit breakers are off, including the main breaker, before connecting the RV to shore power. This precaution prevents any electrical surges or shorts that could damage the RV's electrical system or the converter. Once connected, gradually turn on the breakers and observe the operation of the converter, ensuring it is charging the battery properly and efficiently converting shore power to the correct voltage for the RV's systems.
