Current-Carrying Capacity And Derating Factors For Power Cables And Signal Cables - Siemens S120 Manual

10.6.3 Current-carrying capacity and derating factors for power cables and signal
cables
The current-carrying capacity of PVC/PUR-insulated copper cables is specified for routing
types B1, B2 and C under continuous operating conditions in the table with reference to an
ambient air temperature of 40 °C. For other ambient temperatures, the values must be
corrected by the factors listed in the "Derating factors for deviating ambient temperatures"
table.
