Had a service call today....a customers baling machine at a clothing factory had blown a fuse. The main 600
V 60A fuses at the disconnect were fine. I opened up the control box of the unit and found original factory installed 3 - 600V td dual element 35Amp fuses and one was blown. My question is, the nameplate on the machine says max 21.5amps, why and what protection does 35amp fuses provide? Why didn't the factory use 22-25 amp fuses?
