    摘要: An air conditioner includes an air conditioning unit, and three wiring lines for supplying power to the air conditioning unit. The three wiring lines are a pair of single phase AC power lines and an earth line which are to be connected to three source lines. The three source lines are a pair of single phase AC source lines and a ground line. The air conditioner also includes a detection unit including a detecting device that detects voltages between each of the AC power lines and the earth line, a conversion device that converts the voltages detected by the detecting device into logic level signals, a comparator that determines presence or absence of faulty connection between the three wiring lines and the three source lines by comparing the logic level signals obtained by the conversion device with reference logic level signals, and an output device that shows a result of determination made by the comparator.
