Gidday feather,
Welcome to the group.
The reasoning behind that is on-going inspection, it's looking at things like potentially loose connections, wires that are overheating, just things like that.
Surfin,
Fault currents are getting higher, because the lines feeding installations and transformers are getting bigger.
Bigger wire size equals less impedance equals higher available fault current.
Ipscc = Vsource/System Impedance.
