Current-carrying capacity for power 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 from the "Derating factors" table.
