Hi,
I have had a electrician look and confirm that what I saw in junction box in A/C is #14 wire to unit (not #12) and it is a 15 amp breaker. I have sent two emails to Tiffin to ask about there recommendation for replacement A/C and have not heard back yet. I am not upset, I really enjoy and like my motorhome, I understands it takes a few days sometime to respond. As I previously posted, I just looking for a answer to what is the replacement unit for the "High-Effency Brisk-Air" 15 amp unit from installed on my unit; and possibly if anyone has tried to repull wire to A/C unit.
Are you the original owner? I have seen where the OEM installed the AC unit on a 15 amp breaker, when the correct 20 amp was in the breaker box. You just move it over. As to the 14 versus 12 gauge. There is NO PROBLEM running a roof AC on a 14 gauge wire. The AMP ratings on the various model AC/HP units just vary no more than 3 amps max (11.5 to 14.5). You CANNOT "pull" a new wire threw the existing wire cavity. The Minimum wire size stated by the AC makers is 12 gauge, but having/using 14 gauge is OK. I just find it hard to believe you have 14 gauge FROM Tiffin AND on 15 amp breakers if you are the original owner. Doug (Tiffin dealer Tech for 34 years)
