If Ze is established by enquiry or calculation, it might also be essential to acquire a determined value to verify that the desired ways of earthing is both present and of the anticipated value. Verifying that the earthing conductor is of adequate cross sectional location. Establishing, figuring out or conrming the presence and competence of circuit protective conductors for both the nal circuit(s) and any kind of distribution circuit(s) developing part of the addition or modification.
