Input current, fuse and cable size ratings
The input current is affected by the supply voltage and impedance.
Typical input current
The values of typical input current are given to aid calculations for power flow and power loss.
The values of typical input current are stated for a balanced supply.
Maximum continuous input current
The values of maximum continuous input current are given to aid the selection of cables and fuses.
These values are stated for the worst case condition with the unusual combination of stiff supply with
bad balance. The value stated for the maximum continuous input current would only be seen in one
of the input phases. The current in the other two phases would be significantly lower.
The values of maximum input current are stated for a supply with a 2 % negative phase-sequence
imbalance and rated at the maximum supply fault current of 100kA.
