<p>PURPOSE: A wrong wiring detection device and an air conditioner comprising the same are provided to prevent the damage or the malfunction caused by wrong wiring. CONSTITUTION: A wrong wiring detection device senses the wrong wiring of three-phase power supply by using the current in the neutral line in the three-phase power supply. When the three-phase power supply is applied, the current in the neutral line is sensed and the power is supplied according to the sensed current. The wrong wiring detection device comprises a first switch and a first detection lamp. The first switch is turned on or turned off according to the sensed current to control power supply.</p> |
