why we generally use 3.5 core cable or in other word 1/2
core for neutral and also confirm me that in balance
conditiob(3 phase)current in neutral will zero

Answer Posted / sangekar vaijnath
Generally it depend on load, If cable is used for inductive
load e.g.motor, if there is any fault then 1/2 core is
sufficient to carry fault current due to lagging power
factor. However, in resistive load we are using 4 core
cable since there is no power factor.

I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
