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 NOTE 2: BS EN 1992-4

NOTE 2: BS EN 1992-4 is published in conjunction with a UK National Annex as well as three accompanying Technical Reports (TR):

In Annex B (normative) specifications for the opening of the coupler have been added

BS EN 16602-70-39 can also be used for weld activities on space-related ground equipment and development models for flight hardware

BS EN 50395:2005 contains the electrical test methods required for the testing of harmonized low voltage energy cables

ISO 9994 specifies requirements for lighters to ensure a reasonable degree of safety for normal use or reasonably foreseeable misuse of such lighters by users

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 NOTE 2: BS EN 1992-41 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
