In accordance with Regulation 543-01-03 of BS 7671, two methods may be used to size earthing conductors or circuit protective conductors …
EARTHING
electrical.theiet.orgBS 7671 provides two methods for sizing protective conductors including earthing conductors (see also Table 54A). The easier method is to determine the protective conductor size from Table 54G but this may produce a larger size than is strictly necessary, since it employs a simple relationship to the cross-sectional area of the phase conductor(s).
