The embodiment of the utility provides a system for monitoring electric current in electrical equipment, and the system comprises a household terminal and a plurality of intelligent sockets. The household is in wireless connection with the plurality of intelligent sockets. The plurality of intelligent sockets is respectively connected with the electrical equipment. After the household terminal receives a startup instruction from to-be-started electrical equipment, the startup instruction is sent to the intelligent sockets in the condition that the sum of the electric current in the to-be-started electrical equipment and the actual operating electric current of already-started electrical equipment provided by the intelligent sockets does not exceed breaking capacity. The electrical equipment is only started in the above condition, which, thereby, protects the total operating electric current from exceeding the breaking capacity after new electrical equipment is started and solves the problem that the total operating electric current exceeds the breaking capacity.
