The SCCR originates from changes enacted by the National Electric Code and is represented as UL508A. SCCR ensures proper documentation of the maximum short circuit current a component, assembly or equipment can safely withstand when protected by a specific overcurrent protective device. For instance, a control cabinet’s SCCR is the same as that of a component in the cabinet’s electrical distribution path with the lowest SCCR. Wago Corp.www.wago.us800.346.7245
