    Trane cvhe 800 , 460 volt.

    Looking for solutions, I have a chiller that trips chiller breaker on starter when transitions through generator test at a hospital, generator is sized for chiller. Its a ch530 platform. Chiller runs good and no motor issues. Breaker settings have been adjusted to manufacture recommendations. Any suggestions???

    What type of starter is on the machine? I take it that the main circuit breaker for the chiller is tripping...not just a fault through CH530?

    You might try to change it to an open transition and see what happens. I would love to get to troubleshoot this, I suspect a drop in voltage during transition, time to sell a soft start.

    I would be lying if I said that this didn't bother me. How was it "sized"? If it is sized just for the chiller RLA then the voltage regulator probably isn't big enough to handle the large transition spike.

    Does that mean the additional load of the chiller or just the chiller by itself ?

    Good friend was with JCI but they sold out to CBRE so he's there now. Oversees the AT&T account. Boy did I get an eye opener when I walked thru one of those buildings.
