Not sure how to work out earth fault on this supply. It's only a supply that is being worked out and no where has stated what is being used on the supply

As this is 5 core SWA then all conductors are the same size so easy to work out R1+R2.
If they haven't given you a Ze or earthing type you could assume TNC-S and work out from there.
