1.5mm Twin And Earth Current Carrying Capacity
The table below shows the current carrying capacity of 1.5mm twin and earth cable. This cable is mainly used for larger domestic lighting circuits rated at 10 AMP, This is also a common cable to use in shop and office lighting. As you can see the amount of current the cable can take depends on how the cable is installed, Clipped direct is the larger current rating as it allows the cable to cool and dissipate the heat out better than when its buried into a wall. This table also covers the rating of 1.5mm twin and earth.
