PROBLEM TO BE SOLVED: To provide an incorrect wiring detecting device capable of determining whether a compressor and a compressor control board corresponding thereto are correctly connected or not. SOLUTION: This device detects the incorrect wiring between the compressor and the compressor control board in an outdoor unit 10 including the plurality of compressors 1, 2 and the compressor control boards 4, 5 corresponding to each of the compressors. This device includes a detecting means 20 for detecting a physical amount changed by an operation of one of the plurality of compressors, a comparing means for comparing the physical amount or the change of physical amount detected by the detecting means and a prescribed threshold value, and a determining means for determining whether the plurality of compressors and the compressor control board corresponding to each compressor are correctly connected or not on the basis of a result of the comparison by the comparing means.
