The present invention discloses a current detection and precaution alarm device consisting of a current sensing device, a current voltage converter, an alarm device, a selection adjusting button and an illumination device, and primarily used in a current loop of an electric power system for detecting a current signal of the current loop without changing any original power circuit of the electric power system or preparing an operating power supply. If the detected current quantity exceeds a default setting, sound and light alarm signals will be generated to remind users to reduce the power consumption and prevent a possible risk or a sudden power failure caused by a current overload, so as to improve the practical value and electric safety of a product.
