Electric cables. Calculation of the current rating. Thermal resistance - A method for calculating reduction factors for groups of cables in free air, protected from solar radiation Ingestion-build-89079 BS 6891 gives you comprehensive1 Scope The method described in this International Standard is applicable to any type of cable and group running horizontally, provided that the cables are of equal diameter and emit equal losses. Information is provided on the reduction in permissible current when cables are mounted adjacent to each other. It is limited to the following cases: a) a maximum of nine cables in a square formation, see Figure 1, and b) a maximum of six circuits each
