Not where I really want to be
Is the built in circuit breaker on an air handler ok to be considered a disconnect within sight?
Do you have to install another disconnect within sight even if the AHU has a built in circuit breaker acting as a disconnect?

Agree, it complies as the means of disconnect within site.
The circuit breaker built into these air handlers do not act as over current protection, only as a disconnect so the size of the breaker is not relevant. It could be a 60A breaker for an AHU that has a maximum OCP of 50. The breaker that feeds this circuit is relevant to size and max ocp. Thanks for answering and participating.
 
I see that as an option on RTU's when specifying the model number. You can usually get them with a unit mounted nonfused disconnect or a unit mounted circuit breaker. Why would you chose one over the other?
