Hi I am new to this forum.

We do a lot of work with a local HVAC company. For the above A/C installation we would run 8 wire with a 40 amp breaker, then fuse it down to 35 amps. In our experience in dealing with the service department with this company doing this has reduced service calls. For this A/C unit 10 wire with a 30 amp breaker will work for the distance mentioned, but if there is a small deviation in voltage drop the breaker WILL trip. The manufacturer of the condenser (york) even reccommends running the max size mentioned in the nameplate and fusing it to the proper size.
