Im looking at a service that was designed and installed and not to old.
Right now the LCD logic board on the main has burned out. The three cooling fans for the trans coils never had fuses installed and looks like everthing is getting hot. I am not in charge of doing any thing here. I am just curious. I only have minor numbers on loads.
I know the Trane chiller is about 320 amp @ 480 and the Other Chiller is 320 or so. This seems all fused from a 900 amp Breaker. From a 750 KVA trans. Service I am curious is max already, Or over. Plus the fact. What happens when fire pump kicks in ?? Please any polite input.
