WebMar 16, 2000 · The first approach would be to apply a SPD with an AIC rating of 42,000 amperes or greater. Even though the circuit breaker proceeding the SPD is greater than the SPD, the maximum short-circuit current available at the panel is 42,000 amperes. Therefore, the SPD has an AIC rating equal to the power distribution system at that point. WebNo. Standard relays do not carry an AIC rating because they are not overcurrent protection devices. A Lutron relay panel has an SCCR, but not an AIC rating. AIC ratings are only for overcurrent protection devices. Standard Lutron switching panels use branch circuit breakers with an AIC rating of 10 kA (120 V panels) or 18 kA (277 V panels).
