Yesterday I commented that there was almost no detail in the question and the answer referred to a 2. d) The connection must be made using clamps ( to BS 951) and be suitably protested against corrosion at the point of contact. Earth cables offer protection against accidental electric shock by providing a route for current that would otherwise pass through a person, by limiting the increase in voltage that can occur in a device. b) Bonding connections to incoming metal services should be made as near as practicable to the point of entry of the services into the premises, but on the consumer’s side of any insulating section. is a non standard size protective conductor size, so the next size up is 10mm2 is acceptable, which saves money installing a 16mm2.Remember BS7671 is not a legal document so everything is "interpretation" and even using the on-site guide it is not "legally" binding and generally is written way way to the safe side of the regs. a) Only copper conductors should be used: copper covered aluminium conductors or aluminium conductors or structural steel can only be used is special precautions outside the scope of the Wiring Guide are taken. c) Where practicable, the connection to the gas, water, oil, etc service should be within 600mm of the service meter, or a point of entry to the building if the service meter is external and must be on the consumer’s side before and branch pipework and after any insulating section in the service. The distributor may require a minimum size of earth conductor at the origin of the supply of 16mm² copper or greater for TN-S and TN-C-S supplies.

Would I consider sizing it to half of the combined area of the 3 (240mm2) size as in half of 720 mm2 or half of each 240mm2 .A qualified electrician will understand the Adiabatic is the last part of any electrical calculation. Guidance on earth conductor and protective bonding conductor cross-sectional areas is given in the guide to the wiring regulations BS7671. In the situation, you describe the calculation would need to be completed to determine whether the earthing conductor is adequate. Also used in connection to meters • Blue, inner core • Compliant with BS EN 6004 • Temperature rating: -15°C to +70°C • Min.

If your doing one or two runs and the cost isn't important then fair enough, use the standard size in the wiring regs as a guide. This 16mm² Single Core Earth Cable is suitable for power and lighting circuits, building wiring, use in conduits and closed installation ducts and internal appliance wiring. The fault current is the electrical current which flows through a circuit during an electrical fault condition. Earthing is a safety measure to prevent electric shock, whereas bonding is a term used for connecting together all the metallic parts that are not supposed to be carrying electric current .The adiabatic equation is based on the assumption the earth fault current is so short that none of the heat energy produced in the protective conductor escapes before the protective device operates.
