ABSTRACT:
An identifying apparatus for an arrangement of an alternating current (AC) power supply includes a detecting circuit and a control circuit. The AC power supply includes a hot line and a neutral line. The detecting circuit is electrically coupled to the hot line and the neutral line of the AC power supply. The AC power supply supplies power to an electronic device via the control circuit. The detecting circuit detects connection status of the hot line and the neutral line of the AC power supply and generates a detection signal to the control circuit. If the hot line and the neutral line are swapped, the control circuit prevents the AC power supply from supplying power to the electronic device.
