I want to Thank jamawieb for His wisdom, The Idiot award for today go's to Ding, Ding, Ding "MYSELF" I got myself into trouble again assuming my 10Kw Gen was complete with only 40 hours on It and had the correct 10Kw AC box. I got to thinking about what jamawieb said about the CVT1's being different on the 5Kw and the !0Kw so this morning I checked my 10Kw to see the wraps on the CVT1 and It was staring right at me, I had a 5Kw AC box on a 10Kw Gen. No wonder my breaker was tripping. Now I have a brand new breaker for a paper weight. It just go's into Parts Stock? The moral of this story Is, If your Breaker Is Tripping when It shouldn't be, check you AC Box first.
