FLC (Full Load Current) Incoming = outgoing current at full load
Self Induction A coil induces voltage in itself when current
changes
Mutual Induction Two coils induce voltage on each other
Turns Ratio Voltage ratio = turns ratio
Fuse Sizing KVA/3=Fuse Size; Fusing should be 200-250% of
expected load current
Fault Current FLC/Z=Fault Current
