2.5mm Armoured Cable Current Carrying Capacity – Below is a list of specifications relating to the 2.5mm Armoured Cable. This cable is mainly designed for powering 32A ring mains and 16A radial circuits.
The method of installation will affect the current carrying capacity of the cable. Clipped direct provides the largest current rating as it allows for the cable dissipate heat as opposed to when the cable is installed into a wall or structure.
