An electrical device is provided to prevent a fire due to a heat of a terminal by always monitoring temperature of the terminal according to a light emitting color of a LED. An electrical device includes a plurality of terminals and a safe cover. The safe cover prevents exposure of the terminal. A PCB is mounted in the safe cover. The PCB includes a sensor part(310), an A/D converter(340), and a MPU(Micro Processor Unit)(350). The sensor part includes a temperature sensor for measuring the temperature of the terminal. The A/D converter converts an analog signal of the sensor part into a digital signal. The MPU processes a signal received through the A/D converter. The MPU includes a signal correction part. The signal correction part includes a variable resistor for correcting resistance of the temperature sensor.
