Re: AIC ratings
Neither the designer nor the builder calculates the aic of the equipment. That information comes from the manufacturer. What must be calculated is the aic available at the equipment.
110.9 Interrupting Rating.
Equipment intended to interrupt current at fault levels shall have an interrupting rating sufficient for the nominal circuit voltage and the current that is available at the line terminals of the equipment.
Equipment intended to interrupt current at other than fault levels shall have an interrupting rating at nominal circuit voltage sufficient for the current that must be interrupted.
