If we tell 60 sq.mm. 3-1/2 core cable,then what does it mean
?
1) Each core section in the whole cable is of 60 sq. mm.
2) The whole cable is of 60 sq. mm. which is sub-divided
into 3-1/2 core.
Answer Posted / binod
3cores are 60 sq.mm & 1/2 is less than 60 sq.mm this type
of specification is meant for cable size(3phase and one
neutral)

why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?
