I guess an update is needed. Had trane guy out twice. The install manual leaves some to interpertation. The factory also doesn't seem to support the product anymore. It was offered as a low cost solution versus updating the panel. We got the machine to roll over and start /transition ok. Could not throw a load on it. We downrated the max. amps from 610 to 'bouts 585.(We had the sparky supervisor with us and confirmed max. hi volts he has seen - 500, machine rated at 460). Most we could get the machine to ramp to was 340. We'll have to wait till summer of 2010 to see the net results.
Thank you for all your replies, guys.
