†Details of other multicore designs are available upon request.
*The tabulated rating is as a two core cable and may be used where the number of cores carrying current does not exceed the square root of the total number of cores.
Installation methods for current rating in accordance with BS7671/IEE Wiring Regulations.
The tabulated ratings are based upon a 30°C ambient temperature and 90°C operating temperature. For other ambient temperatures or where cables are grouped together, the appropriate rating
factors should be applied.
