Can I use Mike's fault current program to calculate the AIC for a 200A main breaker on the 208v secondary side of a 75 KVA 480v-208v transformer?
I know the fault current of the 75kva transformer, as well as the length and type of feeders from the transformer to the main breaker? The 100A breaker on the primary side is rated @ 30KAIC.
I used the program for the secondary, and it came out less than 10KAIC, which makes sense to me.
Want to check with the experts first.
Thanks in advance
