The invention discloses a residential user distribution box having a voltage deviation indication function. The residential user distribution box is internally equipped with various control components, and a monitoring circuit board is arranged in a box door of the residential user distribution box at an upper part; the monitoring circuit board comprises a diode, a voltage stabilizing diode, a first bidirectional trigger diode, a second bidirectional trigger diode, a first resistor, a second resistor, a third resistor, a first potentiometer, a second potentiometer, a first indicator light, a second indicator light and a third indicator light, and light-emitting ends of the indicator lights are exposed to the outside the box door; and two input ends of the monitoring circuit board are connected with a power input end in the residential user distribution box. The residential user distribution box having the voltage deviation indication function is reasonable in design, simple in structure and easy to manufacture, and can automatically monitor supply voltage, and when a deviation of the supply voltage occurs, light-emitting indication is automatically made, thereby reminding people to turn off electrical appliances in time, and guaranteeing using safety of household appliances.
