CALCULATION OF CURRENT CONDITION: BUILDING WIRE L.V.; 80°C

CURRENT CAPACITY VALUES AND CURRENT CALCULATION CONDITIONS BASED ON IEC 60364-5-52:2009 :

TABLE B.52.2 (METHOD A1: Two single-core cables in conduit in a thermally insulated wall).
TABLE B.52.10 (METHOD F: Two single-core cables in the air in flat formation and in contact).
Maximum conductor temperature : 80°C.
Ambient air temperature : 30°C.

The above values were corrected with a correction factor for the operating temperature of 80°C.
