My house has a 10 gauge wire leading to a 50 amp breaker. My understanding is this is not allowed and the conversation should end there.
However, this circuit is for the AC unit which specifies a minimum circuit amps of 33 amp and a maximum breaker of 50 amp. HVAC folks are telling me the 10 gauge wire is fine in this case. Why is it acceptable to seemingly violate the normal code specifically for an AC unit?
