Does anyone know of a database or published study on the number of overurrent device failures due to improperly applied AIC ratings and non-compliance with 110.9 of the NEC?
I am curious to how often failures have occurred or how likely a failure would to occur if devices with insufficient AIC rating are installed on systems with higher available fault currents.
