Its must for the capacitors. If the frequency of charging &
discharging is increased it will take & deliever a huge
current at all the charging & discharging cycles. So the
cable will get hot quickly, if it is not reated properly.

In a 3 phase 4-wire system. For a 3.5 core cable if all loads are single phase and balanced, what will be neutral current? will it be sum of all phase currents? Or it will be zero? And if loads are unbalanced what will be neutral current?
