I really ought to already know the answer ... but I'd like to see your take on this issue.
An air conditioner is being installed. The A/C specifies that the circuit have a minimum ampacity of 28 amps, and a maximum OCPD (breaker) of 40 Amps.
The engineer has specified the 40 amp breaker, #8 wire, and a 30 amp disconnect.
In this situation - where the NEC allows for a larger breaker than usual - is it allowed to place a 30 amp disconnect on a circuit protected by a 40 amp breaker?
