The utility model discloses an alarm type electric energy metering combined junction box comprising a body, in which are disposed a plurality of groups of voltage loop modules, current loop modules, and a zero line module, which are alternately arranged. The top surface of the body is provided with an isolation layer, and the isolation layer is provided with an alarm circuit which is connected with the voltage loop module and the current loop module. The alarm circuit comprises a divider resistor and a light-emitting diode, and the light-emitting diode is connected with the divider resistor inseries. According to the utility model, the light emitting diodes are additionally arranged on the voltage loop and the current loop of the existing electric energy metering combined junction box respectively; faults in the wiring process of all phases of circuits can be visually and preliminarily judged on site through the brightness of the diodes, an alarm function is achieved, personal safetyand equipment safety are prevented from being endangered, faults can be found and solved as soon as possible, electric quantity loss is reduced, the structure is simple, and practicability is high.
