## How do I choose cable size from KW?

To decide 95 Sq.mm cable, cable selection condition should be checked.

1. Cable derating Amp (187 Amp) is higher than full load current of load (139 Amp) = O.K.
2. Cable voltage Drop (2.2%) is less than defined voltage drop (5%) = O.K.
3. Number of cable runs (1) ≥ (139A / 187A = 0.78) = O.K.
