WebJul 28, 2024 · Unfortunately we must follow BS7671, and this says that - for copper - the minimum csa of a buried earthing conductor connected to an electrode is: - 2.5mm if protected against corrosion and mechanical damage. - 16mm if protected against corrosion but not mech damage and - 25mm if not protected against corrosion or damage. WebJun 9, 2024 · A cpc can be either sized to table 54.7 in bs7671 or calculated using the adiabatic equation. An equal sized cpc to the line conductors is rarely required, especially when current limiting ocpd’s such circuit breakers and fuses are used.
