2.5mm Twin And Earth Current Carrying Capacity
The table below shows the current carrying capacity for 2.5mm twin and earth cable. This cable is mainly used for 32A ring mains and 16A radial socket circuits in domestic houses and offices. As you can see the amount of current the cable can take changes depending on how the cable is installed, Clipped direct is the larger figure as it allows the cable to cool and dissipate the heat out better than when its inside the wall.
