Ampere interrupting capacity (AIC) rating is the OCPDs ability to withstand current and still open (disconnect) a circuit. This rating is typically hundreds of times the current rating of the breaker with a typical 15 A household breaker having an AIC rating of 10,0000 A. AIC ratings are typically not relevant in the case of off-grid PV systems.
