Inspected a 6-yr. old Rheem central A/C unit today. Rheem lists 25 amp max fuse. Panel reveals a 30-amp breaker, dedicated, protecting the circuit. Conductor size is 12 AWG. Should this have been wired with 10 gauge??? Or is this not really an issue?

Look at your data tag again. It will list a minimum circuit ampacity. That is the minimum size the wire should be. Then it will tell you the maximum size the breaker or fuse should be. The breaker will often be larger than the wire - thats OK as long as it is in the parameters of the data tag.


If the data tag says the maximum fuse or breaker should be a 25 AMP and its a 30 AMP its wrong.
