Ambient temperature rating factor (Ca)

Ambient temperature rating factor used for calculating theminimum required cable size. For cables installed in air, values for this factor are given in BS7671:2018 Table4B1.For ground installations, values are given in Table4B2. Elevating the ambient temperature will result in a lower rating factor Ca.This may result in an increased cable size.
