Could somebody please put me on track.
Main bonding conductors are sized relevant to earthing conductor (TN-S / TT) or PEN conductor (TN-C-S).
On a large installation (Industrial / Commercial) with multiple buildings containing Extraneous parts should ALL the bonding conductors be sized the same throughout according to origin or sized accordingly with supply to that specific building??
