Though often used as such, “interrupt rating” and “short-circuit current rating” are not interchangeable terms. Unlike the interrupt rating, which defines the performance limit of an overcurrent protection device (e.g., circuit breaker or fuse), the “short-circuit current rating” identifies the mixed color cabinets in kitchen
