General
When selecting the conductor cross-section, other criteria may have to be taken into account, such as requirements for protection against electric shock (see DIN VDE 0100-410), for protection against thermal influences (see DIN VDE 0100-420), for protection against overcurrent (see DIN VDE 0100-430), the voltage drop (see DIN VDE 0100-520) and for the limit temperatures of terminals to which the conductors are connected.
The rated currents listed in the tables are recommended values for uninterrupted operation.
They apply to operation with alternating or three-phase current with a frequency of 50 Hz to 60 Hz and with direct current.
