EARTH CABLE GREEN & YELLOW 6491X PER METER SIZE 16MM

Product Information

Protective conductors (including earth and bonding conductors) of 10mm² cross-sectional area or less shall be of copper. 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 . is a non standard size protective conductor size, so the next size up is 10mm2 is acceptable, which saves money installing a 16mm2. 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. 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.

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 . In the situation, you describe the calculation would need to be completed to determine whether the earthing conductor is adequate. Cable size selection is based on 3 main factors: Current carrying capacity, Voltage regulation, Short circuit rating.

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. A qualified electrician will understand the Adiabatic is the last part of any electrical calculation.

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. 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. Yesterday I commented that there was almost no detail in the question and the answer referred to a 2. Guidance on earth conductor and protective bonding conductor cross-sectional areas is given in the guide to the wiring regulations BS7671.

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. Also used in connection to meters • Brown, inner core • Compliant with BS EN 6004 • Temperature rating: -15°C to +70°C • Min. Aside from the ones needed to make our site work properly we use Google Analytics to monitor how the site performs. 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. The fault current is the electrical current which flows through a circuit during an electrical fault condition.
