Abstract:
1. A load electric current evaluating device, comprising: a load electric current calculating section that calculates a load electric current flowing through a predetermined part of electric wiring including a load part, a protecting part for the load part, an electric wire and an electric power source at a normal operating time; a storing section that stores load part information showing electric characteristics of the load part and protecting part information showing electric characteristics and a rated value of the protecting part; an information reading section that reads the load part information and the protecting part information from the storing section; an evaluation reference providing section that provides an evaluation reference for evaluating adaptability of the load electric current flowing through the predetermined part at the normal operating time with reference to the load part information and the protecting part information; an evaluating section that evaluates the adaptability of the calculated load electric current on the basis of the evaluation reference; and an output section that outputs an evaluation result provided by the evaluating section, wherein the evaluation reference is constructed by a comparison formula in which the load electric current is multiplied by a predetermined coefficient together with the rated value of the protecting part.
