1mm Twin And Earth Current Carrying Capacity
The table below shows the current carrying capacity of 1mm twin and earth cable, referred to as 1mm cable rating. This cable is mainly used for domestic lighting circuits rated at 6 AMP. 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 embedded into a wall.
If you’re looking for a twin and earth with a higher current rating, check out our 2.5mm twin and earth cable. This cable is perfect for your switches and sockets as well as higher power lighting circuits and floodlights.
