Answer Posted / engineer
Right cable size Sellection depends on 3 factors:
1- Load Current.current(I) = 50kW /(1.732*415*0.85
(p.f)) =139A
2- Distance(From feeder to your load)
3- Allawable Voltage droop in your system (Should be less
than 5% )
As experience you can use 10sqrmm for 40A,for 120meter.
