PROBLEM TO BE SOLVED: To provide a power use condition and power selling condition control device with which a power consumer can judge what degree of power is consumed at present or in the future, and where electric devices in use do not consume wasteful power, and which can save power consumption and promote the introduction of a private power generator. SOLUTION: A power use condition display device is structured so that first indirect current detection means 3 (3-1, 3-2, 3-3,...) capable of indirectly detecting power in use are mounted on at least one part 2 of an indoor side wiring part in a distribution panel 1, and the output values from the indirect current detection means 3 are converted into digital values through an analog/ digital conversion means 4. Using the digital values a power (watt number) for the overall load currently in use indoors is calculated by a proper calculation means 5, and the calculated values are displayed on a proper display means 6 installed separately from the distribution panel. |
