Hi all, Got a call from a customer that they had to reset the front 500 amp breaker on a 2010 RTAC. I arrived at the job and the unit was running as normal. I got them to swap the unit over to a stand by to start checking it out. It was running at full capacity when I arrived. I started checking resistance and megging out things and noticed some odd readings on one of the compressors. I opened up the pecker head on the compressor and the terminals were just dripping wet. The shorting bars had an 1/8" of water standing on them and it was running down the studs. The meg reading was about 5 meg and when i dried it up it went to over 20?
Has anyone else noticed this on their units? I don't know for sure if this was the cause but it seems very odd to me. I know Trane had issues on the old GP screws back in the day with straight top studs like this pooling water when you shut them down but thought they corrected it. Any ideas?
