ELECTRIC CURRENT DISPLAY

PROBLEM TO BE SOLVED: To provide information about a current flowing in a main breaker in a place using an electric appliance temporarily to prevent electric supply from being interrupted fully caused by the overuse of electricity. SOLUTION: This display comprises a main equipment and a sub-equipment used in parallel with the breaker for breaking an electric passage automatically when exceeding a rated current, for setting a monitoring current in response to the rated current of the breaker, and for detecting an electrification current of the breaker to display information about a margin of the electrification current of the breaker with respect to the monitoring current. The main equipment is provided with an electrification current detecting part, a radio reception part and a radio transmission part, the sub-equipment is provided with a radio reception part, a signal processing part and an information display part, the main equipment or the sub-equipment has a means for setting a monitoring current level in response to the rated current of the breaker, and a means for computing a condition of the electrification current with respect to the monitoring current level, and an electric power source of the sub-equipment is supplied from a plug socket in a loading side of the breaker via a plug provided in the sub-equipment, or from a battery, so as to make the place of the sub-equipment movable.
