Answer Posted / nbsubrahmanyam
In 3phase ac system ,In the case of link in neutral, we
should not use fuse.
(neutral is using at distribution level for getting single
phase or 3 phase 3wire 4wire system to supply the power to
the some loads),
Suppose we use the fuse in the neutral line,if any fault
or break occur in the neutral line, but current flows from
phase/line to load and come to neutral wire where it has
break,there will be a chance to shock to human
beings/workers who will do the works regarding the repairs.
we generally putting fuse in phase/line for protecting
the equipment/device from high voltages/currents.if any
fault occur in the phase/line ,current will not flows from
fuse,only it will come fuse hence there is no problem. but
in the case of neutral, the current flows through out
equipment that may lead to creat some problms as mentioned
above.
that's why we w should put only link for neutral in three
phase ac system.
