Basically three type of fault develop in the circuits
1, open circuits
2, short circuits
3,loose conection
4,body short

first three electrical fault are directly not distrub humen
and apparatus and last one (body shor) fault is directly
distrub humen and apparatus
so , body short fault time current is to discharge to
