EARTH CABLE GREEN & YELLOW 6491X PER METER SIZE 16MM
About this deal
d) The connection must be made using clamps ( to BS 951) and be suitably protested against corrosion at the point of contact. 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. 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.
16mm Earth Cables | CPC UK
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.Guidance on earth conductor and protective bonding conductor cross-sectional areas is given in the guide to the wiring regulations BS7671. The fault current is the electrical current which flows through a circuit during an electrical fault condition. Yesterday I commented that there was almost no detail in the question and the answer referred to a 2.

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.A qualified electrician will understand the Adiabatic is the last part of any electrical calculation. 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. Also used in connection to meters • Brown, 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. 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 . Protective conductors (including earth and bonding conductors) of 10mm² cross-sectional area or less shall be of copper.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.
