I recently had an engineer ask me about AIC rating on a standard low voltage relay panel used for switching fixtures on & off. My understanding of the code is the relay is not considered a circuit protection device, like the circuit breaker, but a component of the circuit such as a toggle switch or time clock. I also was told by the factory I rep there really is no UL requirement or guidlines for switching relays to have an AIC rating. Does anyone have any insight into this?
