Hi...NEC 110.9 and 110.10 require that certain parts of an electrical installation be rated for the available fault current (110.9) and have the ability to clear a fault condition without damaging the "electrical components of the circuit" (110.10). Does this mean that every device connected to the power system, such as HVAC control panels, UPS's, Inverters, along with breaker panels (breaker panels always have an AIC rating), etc. that is UL listed must have an AIC rating from the OEM? Or is it limited to only some types of electrical equipment? Thanks.
