Current-carrying capacity for power and signal cables
The current carrying capacity of PVC/PUR-insulated copper cables is speci󹪝ed for routing types
B1, B2, C and E 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 table of derating factors.
