1. An electric device comprising:
- a plurality of loads;
an arc fault detection device to output arc signal detection information when an arc signal has been input from a wire harness connected to the plurality of loads; and
a controller to detect, when the arc signal detection information has been input from the arc fault detection device, a load at which an arc fault has occurred from among the plurality of loads while performing a control operation to sequentially supply Alternating Current (AC) power to each of the plurality of loads.

Abstract
An electric device includes a plurality of loads and an arc fault detection device to output arc signal detection information when an arc signal has been input from a wire harness connected to the plurality of loads. A method includes sequentially supplying, when the arc signal detection information has been input from the arc fault detection device, Alternating Current (AC) power to each of the plurality of loads during a preset time, and detecting a load at which an arc fault has occurred from among the plurality of loads. Thus, a location (load) at which an arc fault has occurred is correctly detected, thereby appropriately coping with (repairing) the arc fault.
