Standard aic ratings
Webbrating. A standard short-circuit current rating can be determined if all of the individual components in the power circuit have a short-circuit current rating. Essentially the component with the lowest rating sets the rating for the assembly. A higher rating can be given by testing a current-limiting short-circuit interrupt device (e.g., a current- Webb10 nov. 2004 · What is the standard I line Panelboard AIC rating?
