A relay module includes: power supply lines; main relay; sub relay with different current capacities. The first power supply line is connected to a main battery, the second power supply line is connected to a sub battery, and the third power supply line is connected to a load. The main relay is between the first and third power supply lines. The sub relay is between the second and third power supply lines. The main relay disconnects when a ground fault occurs in the first power supply line, and connects when a ground fault occurs in the second power supply line. The sub relay disconnects with a ground fault in the second power supply line, and connects with a ground fault in the first power supply line. Whichever one of the main relay and the sub relay has a larger current capacity becomes electrically connected, and the other becomes electrically disconnected.
