Abstract
An electrical apparatus is connected to a power supply and changes operation in accordance with variation of a power supply voltage of the power supply in accordance with drive of another electrical apparatus connected to the same power supply. The electrical apparatus includes a drive unit driven by the power supply, a voltage detection unit, a current detection unit, and a control unit which sets a threshold value with which a circuit breaker which breaks the power supply is not driven, based on (i) a power supply voltage of the power supply detected by the voltage detection unit when the drive unit is driven, (ii) a power supply voltage of the power supply detected by the voltage detection unit when the drive unit is not driven, and (iii) a current detected by the current detection unit when the drive unit is driven.
