The table shows the maximum number of conductors depending on the cable size and pennitted
current for the above mentioned enclosure.
"Conductor" means every conductor entering the enclosure and every internal connecting
conductor. Any cross connections or earth terminals are not counted.

In this area you can add as many
terminals as physically possible.
Maximum physical terminal conten! depends on the terminal dimension and
the maximum pennissible coole size used.
Note:
Maximum pennissible rated current of the applied terminals and cables must be taken
into account. Cables used intemally must be suitable for a temperature between 70° and 80°C.
For larger cables, the number of conductors must be advised by the manufacturer ( with Power
Dissipation Test Report ).
When using the table above, de-rating factors or nominal rated currents in accordance with
IEC 439 should be used.
Different types of tenninals can be used together by utilising the tabular values proportionaJly.
