The following table explains the methods cited above. The way it is installed can have a significant effect on this ability. The current carrying capacity of any cable is dictated by its maximum conductor temperature, and this in turn will be affected by its ability to dissipate heat. 4mm², 6mm², 10mm², 16mm² and higher have stranded conductorsĬurrent carrying capacity (A) for various reference methods (see table below).1mm² 1.5mm² & 2.5mm² have solid (non-stranded) conductors.Not suitable for unprotected use outside (outer sheath materials are vulnerable to attack by UV radiation). ![]() There is an overall sheath of grey PVC (BS 6004), or white for low smoke compound ( BS 7211).Live and neutral are individually insulated, and the Circuit Protective Conductor (CPC) (aka earth) is bare. ![]() This is the most common cable used for domestic wiring today. ![]()
