Web11 de feb. de 2024 · Short-Circuit Current Rating (SCCR) A short-circuit current rating applies to a meter socket or a meter main whether it has a disconnect in it or not. (Learn more about what a disconnect is and the purpose it serves.) The breaker in a meter main has an AIC rating, and that breaker limits its SCCR. WebShort-Circuit Current Rating, n. 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
