I have been tasked with the sizing of a large service to a building. My question is about the AIC rating of the needed devices. We will be having approximately 21-70 amp welder outlets, 1-100 amp aircompressor, approximately 30-120v receptacle circuits, 8-20 amp HID lighting circuits, and about 10 other 3P circuits 20-50 amps. This will all be fed out of a indoor 480/208/120 3Phase transformer.
1? AIC rating of individual devices
2? Derating of total connected load
