Tbe table shows the maximum number of conduclors depending on the cable size and permitted
currenl for the above menlioned enc1osure.
"Conductor" means every conductor entering the enc10sure and every internal connecting
conductor. Any cross connections or earth terminals are not counted.

Maximum physical terminal content depends on the terminal dimension and
the maximum pennissible cable size used.
Note:
Maximum permissible raled current of the applied terminals and cables must be taken
into account. Cables used intemally must be suitable for a temperature between 70° and gO°C.
For targer cables, the number of conductors must be advised by the manufacturer ( with Power
Dissipation Test Repon ).
When using the table above, de-rating factors or nominal rated currents in accordance with
IEC 439 should be used.
Different types of terminals can be used together by utilising the tabular values proportionally.
