*)Each cable brought in and each internal connecting cable counts as a conductor. Jumpers and earthing conductors are not
counted.
**)When using these table values, account may be taken of the simultaneity factor or load factor to IEC 439. The use of a
mixture of fittings with circuits of different cross-sections is possible by pro rata use of the different table values.
