Electrical equipment is mounted in a vehicle. A ground terminal (first connection unit) is connected to a body of the vehicle. An equipment connector (second connection unit) is connected to a switch device (external equipment). A connection switch is connected between the ground terminal and the equipment connector. When the connection switch is on, a current flows through the equipment connector, the connection switch, and the ground terminal in this order. A switching circuit switches the connection switch from on to off when a voltage between the ground terminal and the equipment connector is greater than or equal to a predetermined voltage.
