Answer Posted / jasjit singh
If the electrical system is very efficiently earthed and all
protection are in place then we go for earthed cables and if
you have any doubt about the system earthing and its
protection then we go for unearthed cables. Basically its
the system earthing with which we choose earthed or
unearthed cables. I cannot say which is commonly used
because as I have mentioned earlier it will depend upon your
system earthing. But in few cases even if all protection are
in place and system is properly earthed we still go for
unearthed cables just to have extra safety margins.
