Could you please help me to solve these 2 questions; I did try different ways and got different answers, just want to find where is my mistake:
1) Service panel served from 100 KVA, 1ph, 2% impedance with 1/0 AWG conductor, 50' away, what is the max fault current at panel?
2) 1000A switchboard rated 480V, 3ph, 60 Hz, served from 1000KVA, 3ph, 5% padmounted xfrm, using 3 sets of 400 kcmil copper in non-metallic conduit, 100' away. What is the max fault current at Panel?
Thank you in advance.
