Corrected current-carrying capacity curve (derating curve) A corrected current-carrying capacity curve (derating curve), derived from the [. NOTE: practice, usually the case that all terminals are not loaded simultaneously with the maximum permissible current.. In many cases, the individual terminals can carry several times the derated current indicated the derating curve when less than % of the total complement used. 158 ____________________________________________________________ 0 fu3 <u2 tu\ Ambient temperature Fig.g. the size the wire and unequal distribution the loaded circuits..197), shall specified the relevant detail specification.198: Example current-carrying capacity graph The derating factor justified because the current-carrying capacity may be limited further external factors, e. For these cases, general rules cannot established and the limits must determined for each individual case. This curve takes into account variations specimens as well errors temperature measurements the measuring equipment. 4. these factors result current- carrying capacity other than that which may expected due thermal limitations, then revised value shall apply. .] basic curve (see figure 4. recommended that the method described this standard used accordingly these cases
