Current Ratings
The table below lists the full Thermal current ratings which will raise the Conductor temperature to 85 °C when one cable is installed in free air at an Ambient temperature of 45 °C.
These ratings are applicable for installations which ensure that the operation of the protective device is not greater than 1.45 times the continuous current carrying capacity of the cable.
Where protection is by means of semi-enclosed fuses to BS 3036 the rating must be multiplied by a factor of 0.76.
Note:Sizes 150.0mm², 185.0mm² and 240.0mm², 300.0mm² & 400mm² are classed as dual Rated and are manufactured to UL & BS 6231 only.
