3.5 CORE CABLES ARE USED FOR BALANCE LOAD. IN BALANCE LOAD
THERE IS 0 CURRENT OR VERY LESS CURRENT IN NEUTRUAL WIRE.

Answer / ganesh v

3.5sqmm means the neutral conductor dia will be half of the
main conductor (mechanically weak). In 4 core cables, by
matching phase conductor dia for neutral conductor,
mechanical strength is maintained.
